► The swivel jaws of the SB/SBZ series operate maintenance-free for up to 10 million swiveling cycles.
7. Maintenance
INFORMATION:
The actual service life of the swivel jaws is dependent on many factors:
•Drive with filtered compressed air, dry or lubricated
If operation begins with lubricated air, then the swivel jaws must always be operated
with lubricated air after that
• Operation in one direction, operation with change of direction
• Environmental conditions (humidity, temperature, etc.)
• The performance data for the corresponding use/handling weight
• Shock absorber setting
INFORMATION:
Complete removal of the swivel jaws can only be carried out by Zimmer.
NOTE:
Always ensure that the adjustment screws make contact with the respective limit stop surfaces, so that the shock
absorber does not serve as an end stop.
6.5 End position damping – SBZ series
The following steps should be carried out to adjust the end position damping

moves
► Unscrew the shock absorber by 3-4 turns counterclockwise (decreases damping)
► Loosely attach the locknut
► Remove persons, all tools and other objects from the swivel range of the swivel jaws
► Connect the swivel jaws to the energy supply and fill them with properly prepared air
► Open the adjustment screws of the flow control valves

by a few turns
► Pressurize the swivel jaws with compressed air on alternating sides and check the settings
► If necessary, make adjustments using the adjustment screws of the flow control valves and
by adjusting the shock absorber
► Clamp the shock absorber locknuts
An ideal setting is reached if a uniform swivel movement and an approach to the limit stops with
exhaust air throttling is guaranteed.
