The SCJ50X40-20S features a space-saving design with anodized aluminum construction for corrosion resistance. Its dual cushioning system minimizes impact noise while maintaining precise end-position control. The cylinder body incorporates wear-resistant stainless steel guide sleeves and a chrome-plated piston rod (hardness HRC 45-55) for extended service life. Compatible with both automated lubrication systems and oil-free pneumatic setups.
- Clamping mechanisms in CNC machining centers
- Part ejection systems in injection molding machines
- Conveyor gate actuators in packaging lines
- Material handling in cleanroom environments
- Automated door locking systems
Installation recommendation:
For vertical installations exceeding 45° angle, use a locking nut (M14×1.5) on the piston rod thread.
Maintain 0.3-1.0 MPa air pressure during initial 30-minute run-in period.
Lubricate every 3,000 km stroke distance under normal operating conditions.
