The JSI40X25S features a space-saving design with dual cushioning system for smooth end-stroke deceleration. Its hard-coated barrel resists scoring while maintaining precise air sealing. The cylinder operates effectively in high-cycle applications (up to 3 cycles/sec) when properly lubricated with ISO VG32 turbine oil.
- Clamping fixtures in CNC machining centers
- Paper feed mechanisms in printing equipment
- Actuation of small conveyor gates
- Positioning stages in semiconductor handlers
- Valve switching in cleanroom environments
Installation note:
For vertical mounting, use rod-end support brackets to prevent side load.
Lubricate through air supply (oil mist type) at 1-2 drops/m³. Avoid using in
environments with phosphate ester-based lubricants.
