Mounting the rolling-contact bearings
Take great care and pay attention to cleanliness when fitting and assembling the bearings.
Make sure that you use the correct components for the rolling-contact bearing type in question.
For information about the rolling-contact bearings installed, please refer to the lubricant plate.
Mounting the rolling-contact bearings
1. Heat the ball bearings or cylindrical-roller bearing's inner rings in oil or air at a temperature
of 100 C.
2. Then push the ball bearings or the inner rings onto the shaft at the inner ring of the bearing,
up to its shoulder. Avoid any heavy blows that might damage the bearing.
3. Fill the bearing to the top with the specified lubricating grease (Page 88).
4. Check that the existing sealing rings still perform their function. Replace the sealing rings
if necessary.
Sealing the bearings
● Before installing new felt rings in the bearing cover, soak them in hot, highly viscous oil at
approximately 100 °C, such as DIN 51517-C100 lubricating oil. They must be dimensioned
such that the shaft can move freely, but is tightly enclosed by the rings.
● When installing external V-rings, the V-ring has reached the correct axial position when the
end face of the bearing cover is flush with the outer edge of the V-ring. Use an appropriate
auxiliary installation disk for this purpose.
● Check whether an additional sheet-metal protecting ring has been inserted in the bearing
cover or bearing shield to protect the V-Ring. If so, pay attention to the following points
during assembly:
– The ring has sufficient pretension.
– One of its two slots coincides with the corresponding water drainage slot provided at
the bottom of the bearing cover seat or bearing shield seat.
● If rotary shaft seals without helical springs are installed, also install the replacement part
without a spring.
Speed sensor
● If you are using a speed sensor with an inner V-ring on the outer bearing cover, the V-ring
must be positioned against the shoulder of the shaft journal.
