High-precision industrial cylinder engineered for heavy-duty linear motion applications requiring exceptional stability in long-stroke operations. Features corrosion-resistant construction with precision honed tube and multi-layered sealing system. Requires 40μm filtered air and periodic lubrication every 2,000 km of cumulative stroke movement.
- Automated palletizing systems
- Automotive assembly line positioning
- Large-format CNC machine tool changers
- Solar panel cleaning robot actuators
- Warehouse vertical lift mechanisms
Installation note:
Requires lateral support when stroke/piston rod length exceeds 800mm.
Maintain 0.5-1mm alignment tolerance per meter during rail mounting.
Use rigid couplings only for stroke lengths >1000mm.
