Heavy-duty adjustable stroke cylinder featuring precision-machined aluminum construction with wear-resistant coating. The dual-cushion design minimizes end-impact noise while allowing ±20° rotation adjustment for fine positioning. Includes integrated mounting grooves for sensor installation and anti-rotation guide mechanism.
- Automated assembly line positioning systems
- Plastic injection molding machine ejectors
- Die-casting machine core-pulling mechanisms
- Palletizing robot end-effector adjustment
- Glass processing equipment with variable stroke requirements
Installation note:
Lubricate rod with ISO VG32 hydraulic oil before operation.
For vertical mounting, use rod-down orientation to prevent
piston seizure. Adjust cushion screws in 1/4 turn increments
while monitoring pressure gauge fluctuations.
- Relubricate every 500km of cumulative travel
- Inspect cushion seals every 1 million cycles
- Replace rod wiper seal after 2 years of service
