Refer to the rating plate or the catalog for the designations of the bearings being used.
Prolonged storage periods reduce the useful lifetime of the bearing grease. For permanently
lubricated bearings, this reduces the bearing service life.
We recommend that the grease is replaced after a storage time of 12 months. Replace
greased bearings also in the case of closed bearings (suffix 2Z or 2 RS). After 4 years in
storage, generally replace all rolling bearings and grease.
Recommended interval after which bearings are to be replaced under normal operating
conditions:

● Do not reuse bearings that have been removed.
● Remove the dirty spent grease from the bearing shield.
● Replace the existing grease with new grease.
● Replace the shaft seals when the bearings are replaced.
● Slightly grease the contact surfaces of the sealing lips.
Note
Special operating conditions
The operating hours are reduced, e.g.
When machines are vertically mounted.
High vibration and surge loads
Frequent reversing operation
Higher ambient temperatures.
