High-capacity industrial cylinder designed for heavy-duty linear motion applications. Features precision honed tube with wear-resistant coating and magnetic piston for position sensing compatibility. The extended stroke design accommodates long travel requirements while maintaining stability through dual guide rod reinforcement (optional). Requires 40μm filtered air with 10-20% relative humidity.
- Automotive assembly line clamping systems
- Steel coil handling equipment
- Injection molding machine ejectors
- Paper mill roller positioning
- Shipbuilding fixture actuators
Installation note:
Requires lateral support when stroke/bore ratio exceeds 15:1.
Maintain 0.5mm minimum alignment tolerance between cylinder axis and load movement path.
Use locknuts with 120-150 N·m torque for flange mounting.
