- Press machine overstroke protection
- Automated warehouse shuttle deceleration
- Packaging line conveyor emergency stops
- CNC tool changer positioning buffers
Installation note:
Pre-lubricate rod end before installation. For vertical mounting,
maintain oil port orientation within ±30° from vertical. Perform
10-15 test cycles before full operation. Replace desiccant cartridge
every 50,000 cycles in humid environments.
- Automatic oil replenishment compensates for minor leakage
- Visual oil level indicator with MIN/MAX markers
- Impact force reduction up to 92% compared to mechanical stops
