Heavy-duty industrial cylinder with reinforced end caps and corrosion-resistant construction. Features dual adjustable air cushions for smooth deceleration and reduced impact noise. The SH mounting configuration allows ±5° angular misalignment compensation, making it ideal for applications requiring swing motion absorption.
- Press machine ejection systems
- Steel mill material handling arms
- Injection molding machine clamp units
- Automotive assembly line positioning
- Foundry equipment actuation
Installation tip:
Lubricate piston rod with ISO VG32 hydraulic oil before initial operation.
Maintain 0.3–1.0mm clearance between clevis brackets for thermal expansion.
Avoid side loads exceeding 10% of maximum thrust capacity.
Critical note:
Requires 40μm filtration and air dryer when used in high-humidity environments.
Maximum side load: 120N. Not suitable for vertical downward thrust applications without counterbalance.
