About the Airtac SC50 Standard Cylinder SC50X100
The AirTAC SC50X100 is a double-acting tie-rod cylinder delivering a push force of 982 N at 0.5 MPa (up to 1767 N at 0.9 MPa). With a 50 mm bore and 100 mm stroke, it fits compact automation tasks where a solid 20 mm diameter piston rod provides good column strength for straight-line pushing.
This model features a 21 mm adjustable air cushion at each end to decelerate the piston smoothly, reducing end-of-stroke impact. The body length A is 150 mm, making the total extended length approximately 250 mm. Ports are PT1/4, and the rod thread is M16x1.5.

Where the Airtac SC50 Standard Cylinder SC50X100 Is Used
Part Stops & Gates
The 982 N push force at 0.5 MPa is ideal for stopping cartons or pallets on a gravity conveyor line, providing a firm, repeatable hold without damaging the product.
Clamping & Pressing
Use the SC50X100 for light-duty clamping fixtures and small assembly presses. The 20 mm rod resists bending under the direct axial load of a press-fit operation.
Diverting & Sorting
Actuate a diverter gate or sorting flap in a material handling system. The adjustable cushion allows for high-speed cycling without a hard mechanical stop at the end of the 100 mm stroke.
Is the Airtac SC50 Standard Cylinder SC50X100 the Right Cylinder?
Choose the SC50X100 when your application needs around 980 N of force at standard shop air. If you require more force, step up to the SC63 bore (1559 N at 0.5 MPa); for a lighter, more compact solution, the SC40 bore provides 628 N. The 100 mm stroke is well-supported by the standard rod bearing, but for any stroke over 300 mm, consider an external guide to protect the rod from side loads.
For a direct replacement, match five key points: 50 mm bore, 100 mm stroke, PT1/4 port thread, basic (no mounting accessory), and no magnet. This ensures dimensional and performance interchangeability with an existing AirTAC SC50X100 tie-rod cylinder.
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 SC50X100 FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
Yes, if your old cylinder is an AirTAC SC tie-rod model with a 50 mm bore, 100 mm stroke, PT1/4 ports, and no magnet or mounting accessories. The SC series is not an ISO 15552 profile cylinder, so it will not interchange dimensionally with ISO 15552 types. Verify the body length A (150 mm) and mounting hole pattern match your existing setup.
