SC40×50 Standard Pneumatic Air Cylinder – 40mm Bore × 50mm Stroke – Double Acting
The SC40×50 Standard Pneumatic Air Cylinder is a compact and durable double-acting pneumatic actuator designed for industrial automation, conveyor systems, packaging equipment, manufacturing machinery and general pneumatic applications.
Featuring a 40 mm bore and 50 mm stroke, the SC40×50 provides smooth, controlled linear movement while maintaining a relatively compact overall size. Its robust SC-series tie-rod construction uses a durable aluminium cylinder barrel, rigid end covers and external tie rods for reliable operation in industrial environments.
The double-acting design uses compressed air to control both extension and retraction of the piston rod, making it suitable for repetitive pushing, pulling, clamping, positioning and machine automation applications.

Double-Acting Operation
The SC40×50 contains two pneumatic ports, allowing compressed air to control the piston in both directions.
Compressed air supplied to one port causes the piston rod to extend. Supplying air to the opposite port causes the piston rod to retract.
A suitable directional control valve or solenoid valve can be used to control the cylinder, while pneumatic flow-control valves can be fitted to adjust extension and retraction speed.
Theoretical Output Force
With a 40 mm bore, the cylinder provides approximately 62.8 kgf theoretical extension force at 0.5 MPa operating pressure.
Actual available force will be lower depending on operating pressure, friction, piston rod area, load conditions and installation alignment.
Installation Recommendations
For reliable operation:
- Use clean and filtered compressed air.
- Select pneumatic tubing and fittings suitable for the operating pressure.
- Use flow-control valves where speed adjustment is required.
- Keep the piston rod correctly aligned with the load.
- Avoid excessive radial or side loading on the piston rod.
- Select appropriate cylinder mounting brackets for the application.
- Confirm the required force and operating pressure before installation.
