High-precision industrial cylinder with extended stroke capability, featuring wear-resistant construction and dual-position magnetic sensor slots (sensor not included). The chrome-plated piston rod undergoes multi-stage polishing for smooth operation. Special buffer design reduces end-impact noise to below 75dB. Requires ISO VG32 hydraulic oil mist lubrication for optimal performance.
- Automated palletizing systems in logistics
- Long-stroke press machine operations
- Automotive assembly line positioning
- Plastic injection molding ejectors
- Textile machinery tension control
Installation guidelines:
Maintain 0.5mm minimum alignment tolerance between rod and load.
For vertical mounting, use counterbalance valves. Lubricate every
3 months under normal operation (100 cycles/hour). Avoid side load
exceeding 30N·m.
Critical note:
Stroke length exceeding 1500mm requires additional mid-support
brackets (sold separately). Maximum allowable rod-end play: ±1.2°
