Industrial-grade steel cylinder designed for heavy-duty linear motion applications. Features precision-ground honed tube (Ra≤0.2μm) and dual anti-rotation guides for enhanced lateral load capacity. The 75° adjustable cushioning mechanism minimizes end-impact noise (≤75dB(A)) while maintaining positioning accuracy (±0.5mm repeatability). Requires 5-40μm filtered air with 1-2 drops of ISO VG32 oil per cycle for optimal lubrication.
- Plastic injection molding machine ejectors
- Automotive welding fixture positioning
- Paper roll handling systems
- Hydraulic press auxiliary actuation
- Shipbuilding alignment jigs
Installation note:
Maintain 0.05mm/m alignment tolerance during mounting. For vertical installations,
use M25 locknut (not included) to prevent piston rod rotation. Lubricate weekly
through air line using 10-15cc oil mist for continuous operation.
