- CNC machine tool automatic door mechanisms
- Automated packaging line impact absorption
- Press brake tooling protection systems
- Lithium battery production conveyor stops
Installation guidelines:
Mount vertically with rod facing downward for optimal oil distribution.
Allow 15mm clearance around housing for heat dissipation. Perform initial
50 test cycles at 50% rated speed before full operation. Check oil level
window monthly - green indicator = normal, red = requires maintenance.
