Ultra-slim profile cylinder with stroke adjustment mechanism (75S suffix indicates built-in stroke lock nut). Features low-friction seals for smooth operation under 0.1m/s~1.5m/s piston speeds. The 75S variant includes dual-position sensor slots for magnetic proximity switch installation. Optimal for applications requiring precise stroke adjustment without disassembly.
- PCB handling robots in electronics manufacturing
- Precision clamping fixtures for CNC machining centers
- Variable height positioning in pharmaceutical packaging lines
- Automated shutter control in cleanroom environments
- Material feeding mechanisms with adjustable push lengths
Installation note:
For maximum accuracy, perform stroke adjustment at 0.3MPa air pressure.
Locknut requires 1.2N·m tightening torque. Avoid side load exceeding 15N.
Use with 40μm filtered air and install downstream lubricator if continuous operation exceeds 2 cycles/second.
