A robust ISO-standard pneumatic cylinder featuring precision-machined components and dual cushioning system. The chrome-plated piston rod resists scoring while the anodized barrel provides corrosion resistance. Designed for medium-load applications requiring consistent thrust (max 785N at 0.6MPa). Requires ISO VG32 hydraulic oil mist lubrication for optimal seal life.
- Packaging machine clamping mechanisms
- Conveyor gate actuators
- Automated welding fixture positioning
- Textile machinery tension control
- Automotive part ejection systems
Installation note:
Maintain 0.5mm minimum alignment tolerance between rod and load.
Use flexible couplings for angular misalignment exceeding 0.2°.
Lubricate through air line lubricator (oil mist ratio 1:3000 recommended).
