The SI80X350 industrial cylinder features triple sealing (rod, piston, end cover) with wear-resistant guide rings. Its chrome-plated piston rod (hardness HRC 45-55) ensures corrosion resistance in harsh environments. The 20μm hard oxidation barrel surface treatment prevents abrasive wear. Includes magnetic piston option (add "-M" suffix) for position sensing.
- Plastic injection molding machine ejectors
- Automotive assembly line clamping devices
- Steel coil cutting equipment actuators
- Paper processing machine tension control
- Foundry mold press mechanisms
Installation protocol:
Lubricate with ISO VG32 hydraulic oil before initial use. Maintain 0.3–0.5mm
alignment tolerance during mounting. For vertical installations exceeding 45° angle,
use locknut (AN8) on piston rod thread to prevent unscrewing.
