High-precision ISO 15552 compliant cylinder featuring wear-resistant construction and multiple mounting configurations. The built-in magnetic piston enables position feedback when paired with sensors. Anti-rotation design maintains stability during long-stroke operations, with adjustable cushions preventing end-impact damage. Requires 40μm filtered air and regular lubrication (ISO VG32 recommended).
- Automated assembly line clamping mechanisms
- Plastic injection molding machine ejectors
- CNC fixture positioning systems
- Packaging machine pusher arms
- Printing press paper feed systems
Installation note:
Maintain 0.5-1mm alignment tolerance during mounting. For vertical installations exceeding 45° angle,
use external guides. Lubricate through air ports monthly in high-cycle applications (＞500k cycles/year).
