General safety guidelines
Usage for the intended
purpose
The purpose of split plummer block housings SES is to support
rolling bearings. The function of the seals and covers available as
accessories is the sealing of the bearing position.
Functionality can be expanded through the connection of systems
for condition monitoring and for automatic relubrication.
Usage for any other purpose is not permissible.
Selection and qualification
of personnel
Mounting of split plummer block housings SES must be carried out
by qualified personnel only.
A person defined as qualified personnel:
■ is authorised to perform mounting of the housings
■ has all the knowledge necessary for mounting of the housings
■ is familiar with the safety regulations
Personal protective equipment Personal protective equipment is intended to protect personnel
against health hazards. This comprises safety shoes, safety gloves
and protective goggles and must be used in the interests of personal
safety.
Depending on the mounting location and on the machine or
equipment in which the housings are to be mounted, it may be
necessary to use additional personal protective equipment.
The applicable regulations relating to occupational safety must
be observed.

Split plummer block housings SES
Safety regulations In order to prevent personal injury or damage to property, the follow-
ing safety regulations must be observed during mounting.
Fundamental specifications Secure heavy components such as upper and lower housing
sections, seals, covers and rolling elements against toppling or
falling. Pay particular attention to limbs when setting down or
fitting heavy components together, in order to prevent crushing.
Mounting and maintenance work of all types should only be
carried out when the machine or equipment is stationary.
Environmental hazards Depending on the ambient conditions, safety risks may be present
at the mounting location that are not associated with the housing
but must be taken into consideration in mounting of the housing.
Consult a local safety engineer before starting mounting work.
Observe all safety regulations that are applicable to the mounting
location and to the machine or equipment affected by the
mounting work.
Seal assembly When fitting O rings, use rounded tools only, such as a screwdriver
with rounded edges. A tool with sharp edges may damage the O ring.
Grease Lubricating greases must not be mixed. Use the same grease for
relubrication as for initial lubrication.
CAUTION
Hazard in case of contact with the skin or eyes, or if swallowed.
The grease contains components that are hazardous to health.
Avoid direct bodily contact and wear protective gloves.
Observe the safety data sheet for the grease. 
Cleaning We recommend using volatile solvents to clean the housing com-
ponents since these allow cleaning without leaving a residue.
In this case, pay attention to the compatibility of the solvent used
with the paint coating of the housing. If compatibility is inadequate,
the paint coating may be damaged with the result that protection
of the housing against corrosion is no longer ensured.
WARNING
Risk of injury due to volatile solvents. Hazard through ignition
of vapours or in the case of skin or eye contact, inhalation or
swallowing.
Avoid direct bodily contact and wear protective gloves.
Observe the safety information provided by the manufacturer. 

Schaeffler Technologies MON 92 5
Disposal Dispose of any cloths soaked with grease or solvents, as well as
excess grease, packaging material and any other waste generated in
connection with mounting, by environmentally acceptable methods,
observing the respective legal regulations.
Transport specifications In order to prevent the occurrence of personal injury or damage
to property during transport, observe the following transport
specifications.
WARNING
Swivelling out or falling apart of rolling bearings. Severe personal
injury or damage to property as a result of falling components.
Before transport, secure rolling bearings against swivelling out or
falling apart.

Lifting of heavy components Use suitable technical accessories to lift heavy components.
Familiarise yourself with correct usage of the accessories and
observe all safety regulations relating to the handling of
suspended loads.
Securing for transport after
prior mounting
When transporting a premounted unit comprising a shaft,
bearings and housing, we recommend using a transport restraint.
The shaft should be radially clamped against the housing.
Securing for transport assists in preventing transport damage
such as standstill marks on the rolling bearing.
Attachment point In the case of housings of size SES524-620 and larger, the upper
housing section has an eye bolt in accordance with DIN 580. This is
intended as an attachment point for mounting and dismounting
the housing. The load carrying capacity of the eye bolt allows the
housing, complete with a bearing fitted in the housing, to be lifted.
WARNING
Rupture of the eye bolt in case of overload. Severe personal injury or
damage to property as a result of falling housing.
Aways screw the eye bolt all the way into the housing.
Only use the eye bolt to lift the housing complete with fitted bearing.
During lifting by means of the eye bolt, no other machine or plant
components should be connected to the housing.

Product description The housings are designed in accordance with a modular concept.
Each housing can be fitted with rolling bearings of various diameter
and width series if they have the correct outside diameter for the
housing.
Depending on their design, the bearings can be located either
directly on the shaft or by means of an adapter sleeve. This gives
different shaft diameters for the same bearing size. The spacings
between the shaft and housing body are compensated by means
of appropriately matched seals.

Preparation for mounting
Preparing the locating surface The locating surface on which the housing will be mounted must
be checked before mounting.
The requirements for the locating surface are as follows:
■ sufficiently robust to withstand the static and dynamic loads
occurring in operation over the long term
■ surface roughness Ra ⬉ 12,5
■ flatness tolerance to IT7, measured across the diagonal
■ free from colouration
■ compensation of differences in level between locating surfaces
Level of mounting surfaces A difference in level between the locating surfaces of bearing
housings will lead to misalignment of the shaft,
Figure 3 .
The seals in SES plummer block housings allow misalignments
of up to 0,5° in both directions.
Differences in level must therefore be compensated such that
the misalignment of the shaft is not greater than 0,5°.
Levelling shims can be used for this purpose.
In addition, it must be ensured that the bearings mounted can
compensate the misalignments present.
␺ = misalignment of the shaft
h = difference in level between
locating surfaces

Schaeffler Technologies MON 92 9
Checking the bearing seats
on the shaft
The bearing seats on the shaft must be free from impact marks
and burrs and must have adequate dimensional and geometrical
accuracy.
The requirements for dimensional and geometrical accuracy
of the bearing seats for a tapered bearing bore and location by
adapter sleeve are as follows:
■ diameter in tolerance class h9
■ cylindricity tolerance within IT5/2
The requirements for dimensional and geometrical accuracy of
the bearing seats for a cylindrical bearing bore and direct seating of
the bearing on the shaft are dependent on the operating conditions.
They are generally defined for the specific application by the
designer.
Checking the requirement
for horizontal location
In addition to the foot screws, horizontal location of the housing is
necessary if one of the following conditions is fulfilled:
■ The load angle is between 55° and 120°, Figure 4 .
■ An axial load is present.
The designer of the machine or equipment should check whether
horizontal location of the housing is necessary.
Horizontal location can be achieved by means of pins or preferably
stops in the load direction.
