High-force industrial cylinder with precision-bored aluminum barrel and chrome-plated piston rod. Features dual adjustable pneumatic cushions for smooth end-of-stroke deceleration. The wear-resistant design incorporates dual piston seals and integrated wiper ring for extended service life. Requires filtered air (≤40μm particles) with recommended ISO VG32 lubricator oil.
- Metal stamping press ejection systems
- Automotive welding fixture positioning
- Packaging machine compression units
- Foundry equipment material handling
- Plastic injection molding machine core pulls
Installation guidelines:
Allow minimum 3mm thermal expansion clearance between cylinder and mounting surface.
Lubricate rod weekly with ISO VG32 equivalent grease. Avoid side loads exceeding 15% of
maximum thrust capacity. Use rod-end spherical bearings in misalignment-prone applications.
