About the Airtac SC50 Standard Cylinder SC50X124S
The AirTAC SC50X124S is a double-acting single-rod pneumatic cylinder with a 50 mm bore and 124 mm stroke, delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration, making it a robust actuator for medium-force automation tasks.
This model includes a factory-built magnet (suffix -S), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for non-contact position sensing. The standard TPU seals suit operating temperatures from -20 to +70 °C, and the PT1/4 port thread ensures compatibility with common pneumatic fittings.

Where the Airtac SC50 Standard Cylinder SC50X124S Is Used
Material Handling Pushers
Ideal for diverting or stopping packages on a conveyor line, where the 124 mm stroke provides a clean push and the magnetic piston enables end-of-stroke confirmation.
Clamping & Fixturing
Delivers consistent clamping force for CNC fixtures or welding jigs. The built-in magnet allows sensor-based verification that the part is securely clamped before the cycle starts.
Press-Fit Assembly
Generates up to 1767 N at 0.9 MPa for light press-fit or staking operations. The adjustable cushion tames end-of-stroke shock, protecting tooling.
Is the Airtac SC50 Standard Cylinder SC50X124S the Right Cylinder?
For applications requiring slightly more force, consider stepping up to the 63 mm bore SC63 series, which provides 1559 N at 0.5 MPa. If a shorter, more compact cylinder is acceptable, the 40 mm bore SC40 series offers 628 N. When replacing this cylinder, match five key points: 50 mm bore, 124 mm stroke, PT1/4 port thread, the built-in magnet (-S), and the basic (no bracket) mounting configuration.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC50 Standard Cylinder SC50X124S FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At 0.7 MPa, push force increases to 1374 N. The maximum theoretical force at 1.0 MPa is 200 kgf.
Yes. The -S suffix indicates a built-in magnet, so AirTAC CMSG, DMSG, or EMSG sensors can be directly mounted on the barrel to detect piston position.
