High-torque industrial cylinder featuring triple sealing system (rod seal, buffer seal, wiper seal) with corrosion-resistant construction. The diamond-textured rod surface enhances seal longevity. Designed for heavy-duty cycles (5 million+ @1m/s) with optional magnetic piston for position sensing. Requires 40μm filtered lubricated air (ISO 8573-1 class 4).
- Press machine ejection systems
- Automotive welding fixture clamping
- Foundry mold core pulling mechanisms
- Paper roll handling equipment
- Shipbuilding plate bending machines
Installation guidelines:
Lubricate rod with ISO VG32 hydraulic oil before initial use.
Allow 50mm clearance behind end cover for cushion adjustment.
Use flexible couplings for misalignment >0.5°.
Replace wiper seals every 3,000km of cumulative stroke.
