High-precision ISO cylinder with compact structure and corrosion-resistant design. Features dual adjustable cushions for smooth end-of-stroke deceleration. The wear-resistant rod guide bushing ensures stable linear motion, while the multi-lip seal design minimizes internal leakage. Requires filtered air (25μm+5μm filtration recommended).
- Press machine clamping mechanisms
- Conveyor system pusher assemblies
- Automated packaging equipment
- Plastic injection molding ejectors
- CNC machine tool positioning
Installation tip:
For vertical mounting, add a rod-end locknut to prevent piston rod rotation.
Lubricate through air supply (ISO VG32 turbine oil recommended) for optimal seal life.
Critical note:
Avoid side load exceeding 30N. Use guide units for applications with
significant lateral forces. Maximum permissible rod eccentricity: ±0.5mm.
