High-force industrial cylinder designed for heavy-duty linear motion applications. Features double-acting operation with corrosion-resistant construction and precision honed tube. Requires minimum 40μm filtered air with lubrication (ISO VG32 recommended). Maximum side load capacity: 850N at mid-stroke.
- Automotive production line clamping systems
- Steel coil handling equipment
- Injection molding machine ejectors
- Large-scale material sorting gates
- Paper mill roller positioning
Installation note:
Requires rigid mounting with alignment couplers for strokes >1000mm.
Maintain 0.5–1.5 mm/m parallelism tolerance between cylinder axis and load movement.
Lubricator required if using non-lubricated air supply.
Critical parameters:
Maximum permissible kinetic energy: 5.8 J (cushion adjusted)
Allowable lateral force: ≤1% of maximum thrust
Do NOT use as vertical load support without external guides
