- Press machine overstroke protection
- Robotic arm end effector stabilization
- Packaging equipment cam follower damping
- Elevator car override shock mitigation
Installation note:
Mount with M25×1.5 thread (30mm engagement minimum). Perform 20-30 test cycles
after installation to activate automatic oil distribution. Maintain 50mm clearance
behind buffer for heat dissipation.
