1General Information
1.1 Introduction
■This manual contains important information on how to safely use and operate TwinSpin® reducers and
how to properly install, maintain and dispose of them.
■In the following, TwinSpin® reducers of all series are referred to as "reducers" or "product"
■The operator must ensure that the instructions in this manual have been read and understood by
anyone who will install, operate or maintain the reducer.
■This manual must be kept close to the equipment in which the reducer is installed and used and must
be easily accessible when needed.
■The original of this document has been prepared in Slovak; all the other language versions are
translations of this document. The document is subject to change and may be changed without prior
notice.
1.2 Use of the reducer
■The TwinSpin reducer was designed as a speed reduction and torque transfer device with integrated output
bearing.
■Do not use reducer for any purpose other than that for which it was designed. Do not use the reducer
outside the specified parameter range. Do not modify the reducer or any part of it.
■The manufacturer of the equipment in which the TwinSpin reducer is used is responsible for ensuring
that the TwinSpin reducer is used in accordance with the purpose for which it was designed and must
take into account all possible risks arising from its use and ensure that its unexpected movement does
not cause injury to persons or damage to property.

and understood these instructions. Furthermore, all persons working with reducers must have the
qualifications required for working with this type of equipment.
■Responsible persons (managers, supervisors, foremen) must not allow any person to work with reducers
who does not understand and know the reducer as a mechanical device.
■If the end-user of the product works in the defence industry, or if the product is to be used for the
production of weapons, the product may be subject to trade controls and export regulations. Therefore,
before exporting the product, check the export and trade control conditions and take the required steps.
■If equipment failure or product malfunction can directly endanger human lives, or if the product is used in
equipment that can harm human health (nuclear, space, medical equipment, safety systems, etc.), it is
essential to check it regularly. In this case, contact your sales representative or the nearest dealer.
■If it is to be used in machinery which, in the event of a breakdown, may seriously endanger human life or
damage equipment, appropriate safety precautions must be taken.
■Comply with all laws, regulations and ordinances for this type of product applicable in the country where
the reducer will be used.
2.2 Installation of the reducer
■Installation of reducers must only be carried out by trained persons with specialist knowledge of drive
systems and mechanics.
■Be careful that the reducer does not fall to the ground or hit a metal or hard object during
handling/transport. Damage to internal components and failure of the reducer may result.
■The reducer should not be subjected to high vibrations during assembly as they may cause damage to
internal components.

5
■Before installation, check that the reducer or any part of it is not damaged.
■Do not strike any part of the reducer with any tool, e.g., a hammer, this may cause damage to internal
components and failure of the reducer.
■Do not use a hammer or any impact causing device to mount the reducer in its final position, this may
damage internal surfaces/components and cause the reducer to fail.
■Never install the reducer if it is visibly damaged or has been damaged during shipping and handling.
2.3 Operation of the reducer
■Do not touch the reducer while it is running.
■The reducer heats up in operation. Be careful not to touch its surface shortly after stopping the reducer.
Risk of burns.
■Before changing the lubricant, performing any inspection or making any repairs, make sure that the reducer
with the drive connected is turned off and cooled down.
■Immediately discontinue operation of a reducer that has been unduly overloaded due to improper use or
if the machine has had an accident. If the machine crashes, we recommend replacing the reducer even if
there are no visible signs of damage.
■During maintenance, inspection or repair, make sure that the reducer or any connected components do
not rotate or move and that the reducer drive is switched off.
■Do not expose the reducer to open flames or use it near substances that are flammable or explosive.
■Reducers in the standard version are not surface protected with paint or anti-corrosion coating.
■Do not operate the reducer in wet or corrosive environments, this may lead to damage.
■Do not operate the reducer outside the specified technical parameters listed in the product catalog.
■Do not continue operation if the reducer is damaged or if the surface temperature has suddenly exceeded
60 °C. If your application requires higher operating temperatures and the surface heats up to more than 60
°C, contact the manufacturer.
■Check the reducer for leaks. In some cases, lubricant may cause a small leak from the space between the
dust lip and the sealing lip on the output seal. Remove the excess lubricant and observe if the lubricant
leakage continues.
■Check the noise level during break-in and when the reducer is running. In case of increased noise level
compared to the normal condition, do not continue to operate the reducer. Increased noise levels may
indicate wear or damage to the reducer.

6
2.4 Disposal
■Before scrapping, remove all lubricant from the inside of the reducer.
■The reducer must be disposed of in accordance with the industrial waste disposal regulations applicable to
the country where the reducer has been used.
2.5 EU Directive 2006/42/EC
■The reducer is a mechanical component. It is used in machinesand equipment. It istherefore not machinery
or partly completed machinery within the meaning of Directive 2006/42/EC of the European Parliament
and of the Council. A CE declaration of conformity is therefore not necessary for TwinSpin reducers.
■The reducer must not be put into service or operated until it has been ensuredthat the equipment in which
the reducer is installed complies with Directive 2006/42/EC.

■For safe torque transfer, use Loctite 603 adhesive on the friction joints of the bolt threads
■Thoroughly clean and degrease the friction surfaces of the bolted joint before applying the adhesive
4.3 Sealing components for sealed reducers
■SPINEA offers for all sizes of open TwinSpin reducers a set of sealing components necessary for complete
sealing of the reducer from the input and output. Contact the sales department for more information.
■For sealing TwinSpin reducers, we recommend using seals made of fluoropolymers, available under the
trade names VITON, FKM or FPM.
4.4 Permissible input shaft load
■Since the input shaft of the TwinSpin reducers is supported in roller bearings at both ends, it can be loaded
with radial loads as shown in the figure below. The tilting torque as a result of radial loading is calculated
according to the following formula.

4.5 Installation of TwinSpin reducers
■Use protective equipment when installing the reducer.
■Do not sit on the reducer box or place any objects or mounting hardware on the unpacked reducer during
assembly.
■Do not use a hammer or impact tools during installation. The reducer must not be subjected to shock or
vibration during assembly as this may damage the internal components of the reducer.

15
■Never install the reducer if it is visibly damaged or if it has fallen to the floor during handling. Although the
damage may not be visible, the reducer may be damaged in operation.
■The surface of the reducer is treated with a corrosion inhibitor. Remove all corrosion inhibitor from all
surfaces to be connected to the input and output members. Inhibitor residues adversely affect the
coefficient of friction of the clamping and bolted connections. We recommend the use of hydrocarbon-
based solvents applied at room temperature.
■When installing an open reducer, ensure the cleanliness of the installation site and prevent contamination
of the inside of the reducer with dirt. If the inside of the reducer becomes contaminated with dust, dirt or
metal particles, they will significantly reduce the life of the reducer and may adversely affect the operation
of the reducer.
■The assembly procedure of the reducer may differ from the procedures described in this manual if the
customer uses components designed and manufactured by himself.
■To achieve maximum reducer performance, it is important to pay attention to installation, mounting
accuracy, sealing and lubrication. Most motor adapter flanges are available upon request. If you need
further assistance, contact the sales department or your local sales representative.
■The TwinSpin reducer is a single-stage, high-precision, zero backlash gearbox that can only be used when
properly mounted. The reducer can be mounted and operated in both horizontal and vertical positions.

16
4.5.1 Assembly with direct connection to the motor with the keyway
■Ensure that all screw holes and contact surfaces are free of grease and dirt.
■Mount the motor flange on the input side of the reducer, use the prescribed tightening torques.
■If the motor flange is also a sealing flange, i.e., if it is mounted on an open reducer, fit a suitable O-ring in
the flange groove. To facilitate installation, lubricate the O-ring with the same type of lubricant that will be
used to lubricate the reducer in operation.
■Slowly slide the motor with the shaft oriented correctly into the reducer input shaft. Do not use excessive
force or force to bring the motor to its final position.
■Center the motor and tighten the bolts on the motor, using the prescribed tightening torques.
■If the reducer is open on the output side, seal it with a suitable plug with an O-ring fitted or a rubberized
shaft plug of suitable size.

17
4.5.2 Mounting with adapter (splined or keyway) with smooth shaft motor
■Ensure that all screw holes and contact surfaces are free of grease and dirt.
■If the reducer is open on the output side, first seal it with a suitable O-ring or rubberized shaft plug of the
appropriate size.
■Mount the motor flange on the input side of the reducer, use the prescribed tightening torques.
■If the motor flange is also a sealing flange, i.e., if it is mounted on an open reducer, fit a suitable O-ring in
the flange groove. To facilitate installation, lubricate the O-ring with the same type of lubricant that will be
used to lubricate the reducer in operation.
■If you use a splined shaft with involute splines, make sure it is lubricated with a special lubricant (see chapter
Lubricating the reducer). Failure to do so may result in tribocorrosion, increased backlash and damage to
the splined shaft.
■Slide the adapter onto the motor shaft, put on the clamping collar and tighten it with the correct tightening
torque. Use the tightening torque recommended by the clamping collar manufacturer.
■Slowly insert the motor with the adapter oriented correctly into the input shaft of the reducer. Do not use
excessive force or impact force to bring the motor to the end position. Use gentle motions when sliding the
motor with the adapter to the counter surface.
■Center the motor and tighten the bolts on the motor, using the prescribed tightening torques.

4.5.3 Assembly with coupling
■Ensure that all screw holes and contact surfaces are free of grease and dirt.
■If the reducer is open on the output side, first seal it with a suitable O-ring or rubberized shaft plug of the
appropriate size.
■Fit the sealing flange to the input side of the reducer, using the prescribed tightening torques.
■If the motor flange is also a sealing flange, i.e., if it is mounted on an open reducer, fit a suitable O-ring into
the flange groove. To facilitate installation, lubricate the O-ring with the same type of lubricant that will be
used to lubricate the reducer in operation.
■Fit the couplingto the reducer input shaft. Tightenthe bolts. When mounting the clutch,observe the clutch
manufacturer's mounting instructions and tightening torques.
■Mount the motor flange on the inlet side of the reducer, use the prescribed tightening torques.
■Slide the motor to the other side of the coupling. Do not use excessive or impact force to bring motor to
the final position.
■Center the motor and tighten the screws. Tighten the bolts on the coupling clamp. Observe the tightening
torques prescribed by the coupling manufacturer.

19
4.5.4 Mounting with pulley
■Ensure that all screw holes and contact surfaces are free of grease and dirt.
■If the reducer is open on the output side, first seal it with a suitable O-ring or rubberized shaft plug of the
appropriate size.
■Fit the sealing flange to the input side of the reducer, using the prescribed tightening torques.
■Fit the pulley to the reducer shaft. Tighten the bolts to the prescribed torque. Follow the pulley
manufacturer's instructions when installing the pulley. Slide the pulley on carefully and without applying
shock.
4.5.5 Specific installation warnings
■When installing the G series reducers, all bolts in the carrier body and main ring must be installed and
tightened to the specified torque. Failure to do so may damage the functionality of the reducer.
■When handling and mounting the TS50M, the input shaft of the gearbox must not be subjected to axial or
radial loads to prevent damage to the ball bearings in which the shaft is housed. Such damage to the
gearbox is not covered by the warranty. During installation, it is necessary to eliminate the
compressive/tensile axial load on the shaft by supporting the shaft on the opposite side against the
direction of axial force to prevent damage to the bearings.

5Lubrication of reducers
■Reducers are supplied as standard with Castrol TRIBOL GR 100-0 PD or TRIBOL GR TT 1 PD lubricant.
Alternatively, Castrol OPTIGEAR 150 oil can be used.
■If you have purchased a reducer without lubricant, please contact the sales department for information on
the amount of lubricant required for each size and design of reducer.
■The lubricant change interval depends on the operating conditions. High temperatures, speeds and loads
will reduce lubricant life. In many cases there is no need for relubrication as the reducer is filled with a
lubricant to ensure its long life. If the reducer is oil lubricated, the recommended lubricant change interval
is 20,000 operating hours.
■When changing the lubricant, fill the same volume of new lubricant as you drained from the reducer. For
more detailed information on changing the lubricant, please contact the SPINEA sales department.
■Do not use several types of lubricants in one reducer. Otherwise, the reducer may be damaged.
■If a splined shaft adapter is used to connect the motor to the reducer, always apply lubricant by applying it
to the splined shaft. The lubricant type to be used is KLUEBER Microlube GL 261.
■If the lubricant in the reducer becomes contaminated for any reason, it must be replaced immediately.
Otherwise, there is a risk of damage to the reducer during further operation.
■For more detailed information on lubrication of reducers, please refer to the SPINEA catalogue.
