Prolonged storage periods reduce the useful life of the bearing grease. Check the
condition of the grease if the equipment has been in storage for more than 12
months. If the grease is found to have lost oil content or to be contaminated, the
machine must be immediately relubricated before commissioning. For information on
permanently-greased bearings, please refer to the section titled Bearings (Page 60).
Note
Regreasing
1.
Clean the grease nipples at the drive end and non-drive end.
2. Press in the type and quantity of grease specified (see rating/lubricant plate data).
● Please observe the information on the rating and lubricant plates.
● Regreasing should be carried out when the machine is running (max. 3600 rpm)!
The bearing temperature rises sharply at first, then drops to the normal value again
when the excess grease is displaced out of the bearing.
9.1.2 Cleaning
Cleaning the greasing channels and used grease chambers
The used grease collects outside each bearing in the used grease chamber of the
outer bearing cap. When replacing bearings, remove the used grease.
Note
You have to separate the active parts of the bearings to replace the grease that is in
the greasing channel.
Cleaning the cooling air passages
Regularly clean the cooling air passages through which the ambient air flows,
e.g. using dry compressed air.
Note
Never direct compressed air in the direction of the shaft outlet or machine openings.
In the case of machines with textile fan covers, regularly remove fluff balls, fabric
remnants, and similar types of contamination (particularly at the air passage opening
between the fan cover and cooling fins of the machine enclosure) to ensure that the
cooling air can flow without obstruction.
