1 Safety
The Assembly and Maintenance Manual is a component element of the
product package, and must always be kept to hand as a reference
source.
The Manual must be passed on if the unit is sold on or given away.
If there is anything in this manual which you do not fully understand,
please be sure to contact the manufacturers.
1.1 Symbols used
This manual employs the following symbols to indicate hazards as well
as other types of symbol:
Indicates immediate danger.
Failure to observe this notice entails risk of death or very serious injury.
Indicates a danger carrying a medium to high risk.
Failure to observe this notice may result in death or serious injury.
Indicates minor risk.
Failure to observe this notice may result in light to moderate injury or
damage to property.
Note
Indicates tips on use of the machine and optimising its efficiency.
1.2 Regulation use
The mechanical linear unit is intended for installation in machines, and
is used solely for manipulating, positioning, transporting, palletising ,
loading, unloading, clamping, clocking, tensioning, testing, measuring,
handling and pushing workpieces or tools.
Pay attention to the basic applications of the linear unit set out in
sections 4 and 3.
In order to comply with the EU Directive governing Electromagnetic
Compatibility (EMC), the mechanical linear unit may only be used in
industrial environments.
Any other use, or use for purposes beyond those stipulated, will be
classed as illegitimate. The manufacturers accept no liability for any
loss thereby incurred. The risk is borne solely by the operators.

1.3 General safety
Preconditions for
operation
The linear unit must not be put into operation until the machine or line
into which it is installed conforms to the following:
•Relevant accident prevention regulations
•Generally accepted safety standards
•EU directives
•Standards governing the electromagnetic compatibility of machinery
•Other applicable standards
•Applicable national legislation.
Safe operation
To ensure safe operation, refer to the following documents:
•This operating manual for the linear unit, particularly the technical
data
•The operating manual for the line into which it is installed
1.4 Use in clean rooms (ISO 14644)
The linear units used in clean rooms are fitted with a vent hole
(generally G1/2“) at the basic profile.
The following guidelines must be observed:
•The linear unit must be subjected to a negative pressure of 0.2 bar.
•The linear unit must be relubricated with a grease suitable for use
in clean rooms (basic lubrication carried out using Klübersynth
BEM 32-34).
1.5 Use in explosive environments
The linear units are suitable for use in potentially explosive
atmospheres, but the supplement to these assembly and maintenance
instructions " FM_319_Use-in-Atex-zones-MuW " must be observed.
The following applies to Beta 100-D-ZSA:
The linear unit is not suitable for use in potentially explosive
atmospheres.

1.7 Modifications to the linear unit
Modifications
The linear unit must not be modified, either in its basic design or in its
safety components, without our written consent. Any such unauthorised
modification will void our liability in respect of the unit.
The operating company may only carry out the maintenance and repair
work detailed in this operating manual. Any other measures, such as to
replace wearing parts and components, may be carried out only in
consultation with our service engineers, by the service engineers
themselves, or by us directly.
Installed safety devices must never be dismantled or disabled.
When fitting special attachments to the unit, follow the fitting
instructions provided by the manufacturers!
1.8 Requirements for personnel
The linear unit has been designed and built in accordance with the
state of the art and accepted safety standards. Hazards may
nevertheless be posed when operating it. Consequently, the unit may
only be installed and operated by trained, competent personnel.
All personnel assigned to install, operate, maintain, repair or dismantle
a linear unit must have read and understood this operating manual, and
in particular section 1, “Safety”.
Work on parts carrying live electrical current may be carried out only by
trained electricians. Such work includes:
•Installing safety limit switches
•Mounting a drive unit
•Checking the direction of rotation of the drive

assigned to install, operate, maintain, repair or dismantle the unit with
appropriate instruction, in particular with regard to safety.
We recommend that companies require their personnel to provide
written confirmation of having received such instruction.
Checking the unit
In accordance with EU Health and Safety Directive 89/655/EEC article

Figure 2: Guide elements
A mechanical linear unit converts rotational motion into linear motion
and is used to move loads quickly, safely and precisely from one
position to another. It consists of an aluminium base profile, a moving
carriage supported by a guide element (recirculating ball bearing or
roller bearing guidance system) and a drive element (screw or timing
belt drive).
Depending on its design, the carriage is able to absorb forces and
moments in all directions, and is positively connected to the guidance
and drive elements by way of the so-called drivers.
The base profile is self-supporting up to a certain length, and is
equipped with grooves for mounting.

As an option, the linear unit can be equipped with accessories such as
a cover, screw supports, inductive or mechanical limit switches and
other fittings(see section 6.3).
The effective range can be flexibly configured. Multiple linear units of
the Alpha, Beta or Delta type can be arranged two-dimensionally (2
axes) or three-dimensionally (3 axes).
Driven linear units can be connected to non-driven units of the same
type by a plate, to be able to take large-area loads for example.

Transportation and storage

5 Transportation and storage
The mechanical linear unit is a precision item. Its mechanism may be
damaged by heavy jolting, resulting in impairment of its functions.
Risk of damage by heavy jolting or bending!
Transport the assembled linear unit only with the transit protection
fitted.
To prevent damage during transportation and storage, protect the linear
unit against shaking and sliding as follows:
•Stow it in a box of sufficient size.
•Use packing.
Section 3 lists the unit weights.
Protect the unit against:
•dirt;
•corrosion;
•water;
•and aggressive atmospheres.

Installation and adjustment

6 Installation and adjustment
The linear unit can be attached by the following methods:
•On mounting rails
•By screws inserted into the sliding blocks
•By screws inserted into the factory-fitted tapped hole rails
Install the linear unit on a flat surface. Unit parallelism < 0.2
mm/1,000 mm.
Mounting by the rails with tapped holes in them is the preferable
solution:
for highly dynamic applications;
where the linear unit has only two attachment points.
6.1 Installing the linear unit by mounting rails
Figure 3: Mounting rails (1)
The recommended maximum spacing between the mounting rails is
700 mm.
Procedure
1. Attach the mounting rails (1) loosely in position (figure 2).
2. Align the linear unit axially.
3. Tighten the mounting rails (1)
(for tightening torques see section 3).
