High-precision industrial cylinder with ISO 6432 compatibility, featuring dual adjustable pneumatic cushions for smooth end-of-stroke deceleration. The anodized barrel provides corrosion resistance in humid environments. Requires air filtration of 5-40μm and ISO VG32 hydraulic oil mist lubrication (optional oil-free operation available).
- Automated packaging line pusher mechanisms
- Plastic injection molding machine ejectors
- CNC machine tool clamping devices
- Automotive assembly line positioning systems
- Food processing conveyor gate actuators
Installation guidelines:
Align cylinder axis within 0.2mm perpendicular tolerance. For vertical mounting,
use rod-end support brackets when stroke exceeds 500mm. Lubricate through air supply
(oil mist 1 drop/m³) for optimal seal life. Allow 15mm clearance for cushion adjustment screws.
