A workhorse pneumatic cylinder featuring dual adjustable cushions for smooth end-of-stroke deceleration. The hard-anodized barrel resists wear in high-cycle applications (up to 3 million cycles @1m/s). Optional magnetic piston version (SI40X225-M) available for position sensing. Requires filtered air (5-50μm) with ISO VG32 lubricator oil mist recommended.
- Automatic door actuation in cleanroom environments
- Clamping fixtures for CNC machining centers
- Material transfer systems in conveyor setups
- Packaging machine ejector mechanisms
- Printing press paper feed units
Installation tip:
Align cylinder axis within ±0.2° angular misalignment for optimal seal life.
Use flexible couplings when connecting to guided mechanisms.
Allow 25mm clearance behind end covers for cushion adjustment.
