Due to the various influencing factors it is not possible to predict the service life.
Therefore the oil seals must be inspected regularly. Note the respective inspection
and maintenance intervals in chapters Inspection/maintenance intervals (

The couplings used in the AM, AL, AQ. and EWH adapters are designed to be posi-
tive, puncture-proof and low-maintenance claw couplings. They have a an impact and
vibration-absorbing cam ring (AM, EWH) or coupling ring (AQ., AL). The service life of
cam ring/coupling ring is influenced by various factors, such as:
• Ambient conditions (temperature, chemicals, radiation)
• Operational conditions (starting frequency, impact characteristics)
