High-precision industrial cylinder with extended stroke capability, featuring corrosion-resistant construction and precision ground piston rod. Designed for heavy-duty linear motion applications requiring long travel distances. Requires 40μm filtered air and ISO VG32 hydraulic oil lubrication (optional).
- Automated assembly line transfer systems
- Plastic injection molding machine ejectors
- Paper processing equipment actuators
- Automotive welding fixture positioning
- Large-format CNC machine tool clamps
Installation note:
Requires alignment within ±0.2mm/m to prevent side load. For strokes over 500mm,
recommend using intermediate support brackets. Lubricate through air port with 1-2 drops
of ISO VG32 oil every 500,000 cycles.
Avoid applications with lateral forces exceeding 30N.
When used in vertical orientation, install an emergency brake valve for fail-safe operation.
