Precision stroke-adjustable cylinder featuring a unique dual-locking mechanism for position stability. The through-rod design allows external stroke adjustment without disassembly. Built-in magnetic piston enables position sensing compatibility (sensor sold separately). Includes wear-resistant guide bushings for side load resistance.
- Precision clamping fixtures in CNC machining centers
- Position control in semiconductor handling robots
- Variable stroke applications in packaging machinery
- Automated test equipment with space constraints
- Printing press paper feed mechanisms
Installation notes:
- Align cylinder axis within ±0.5° to prevent binding
- Use flexible couplings when mounting to moving structures
- Lubricate with ISO VG32 turbine oil if operating below -10℃
- Max side load: 15N at full extension
Maintenance:
Replace buffer seals every 500,000 cycles in high-speed applications. Avoid using silicone-based lubricants which may degrade NBR seals.
