Replace the motor
Bosch Rexroth AG
R911347581, Edition 05
The service lives of motor components, such as
seals and bearings, may vary depending on the
operating conditions, such as operation mode,
speed, vibration and shock load, and frequent
reverse mode. We recommend to change the
bearing after 30,000 operating hours. Shorter
replacement intervals may be necessary; cf.
checks during operation . We recommend reg-
ular visual inspections on shaft sealing rings.
Depending on operating conditions, signs of wear
may appear after 5,000 operating hours. If nec-
essary, replace the shaft sealing rings.
