A heavy-duty industrial cylinder designed for high-force linear motion applications. Features precision honed tubing and multi-layered sealing system for smooth operation in continuous cycle environments. The chrome-plated piston rod incorporates a hardened subsurface layer (0.05-0.25mm) for wear resistance.
- Automotive production line clamping fixtures
- Press machinery for metal forming
- Plastic injection molding machine ejectors
- Heavy material handling systems (palletizers/conveyors)
- Paper processing equipment actuators
Installation advisory:
For full-stroke applications exceeding 500mm, recommend using intermediate rod support brackets.
Lubricate piston rod weekly with ISO VG32 hydraulic oil in high-cycle (>500,000 cycles/year) operations.
Maximum side load capacity: 350N at mid-stroke.
