Does not apply to bearings with specific ILM instructions – for replacement
deliveries it is essential to get into contact with the machine manufacturer
regarding installation, lubrication and maintenance.
Relubrication of the raceway system
The bearing should be rotated during relubrication until
a fresh collar of grease is seen to form around the whole
circumference of the bearing gaps and lip seals. It is the
responsibility of the maintenance personnel to ensure that
the correct amounts of grease at individual regular inter-
vals are administered to the bearing, determined by
regular monitoring of the lubricated condition of both
the bearing raceway and gear. The amount of lubrication
will need to be increased and the lubrication intervals
shortened in extreme conditions, e.g. in the tropics, where
humidity levels (moisture) are raised, exposure to dust and
dirt is high, and extreme temperature fluctuations prevail.
Bogie bearings for railway and tram vehicles as well as
bearings for wind energy turbines are subject to special
requirements, and ThyssenKrupp Rothe Erde should be
contacted in such cases.
In the case of partially assembled bearings, or if there
is a long period between bearing installation and equip-
ment commissioning, then appropriate maintenance
procedures will be required, e.g. relubrication under
rotation or ade quate slewing after no more than three
months and there after every three months. Relubrication
is absolutely essential before and after prolonged
shutdown of the equipment.
Cleaning the equipment
When cleaning the equipment, care must be taken to
prevent cleaning agents or water from damaging the
seals or penetrating into the raceways.

Lubrication intervals for the gear
We recommend automatic gear lubrication. This is because
the tooth flanks should always have sufficient grease
applied relative to both the application and the duty. It is
the responsibility of the maintenance personnel to ensure
that the correct amounts of grease at individual regular
intervals are administered to the gearing, determined by
regular monitoring of the lubricated condition.
Note Effective lubrication is essential for the raceway
system and the gearing. This is the only way to achieve
a satisfactory service life.
Advantage Optimum use of lubricant and intervals
increase the availability of the system.
Examination of bolts
The bolted connection must be capable of maintaining
a pre-designated preload during the entire life of the
bearing. Experience has shown that it is advisable to check
the bolt torques on a regular basis and to retighten the
bolts to compensate for any settlement phenomena.
