About the Airtac SC50 Standard Cylinder SC50X250CA
The SC50X250CA is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering 982 N of push force and 825 N of pull force when operated at 0.5 MPa. With a 50 mm bore and a 250 mm stroke, this model is configured with a rear single clevis (CA) mount, allowing the cylinder body to pivot during actuation for applications with angular movement.
This cylinder uses a 20 mm diameter piston rod with an M16x1.5 thread and PT1/4 port connections. The total extended body length is approximately 400 mm, based on a body length A of 150 mm plus the 250 mm stroke. It features an adjustable air cushion of 21 mm at each end to decelerate the piston smoothly, and operates within a standard temperature range of -20 to +70 °C with its default TPU seals.

Where the Airtac SC50 Standard Cylinder SC50X250CA Is Used
Agricultural Machinery
The pivoting rear clevis mount and 982 N force suit the angular movements required in tractor hitch adjustments, chute diverters, and harvesting equipment linkages.
Clamping & Fixturing
Delivers a controlled 250 mm stroke for part clamping in welding jigs or assembly fixtures, where the clevis mount allows the cylinder to self-align with the clamp arm.
Conveyor Diverter Gates
Actuates pivoting diverter gates on material handling lines. The 825 N pull force at 0.5 MPa reliably retracts the gate against product back-pressure.
Is the Airtac SC50 Standard Cylinder SC50X250CA the Right Cylinder?
For applications requiring more force, stepping up to the 63 mm bore SC63 series provides 1559 N of push force at 0.5 MPa. If a lower force and a more compact body are acceptable, the 40 mm bore SC40 series offers 628 N. The rear clevis mount (F-SC50CA) is ideal for pivoting applications, but ensure the load is guided to prevent side loading on the rod, especially at this 250 mm stroke. For direct replacement, match the 50 mm bore, 250 mm stroke, PT1/4 port thread, CA clevis mounting, and the absence of a magnet sensor option.
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 SC50X250CA FAQ
At 0.7 MPa operating pressure, the push force is 1374 N and the pull force is approximately 1155 N (calculated from the 0.5 MPa pull ratio). The maximum theoretical push force at the 1.0 MPa limit is 1767 N.
No, the AirTAC SC series is a tie-rod cylinder and is physically shorter than a standard ISO 15552 profile cylinder, so mounting dimensions and body length will not match. This model is a direct replacement only for another AirTAC SC50 tie-rod cylinder with the same 250 mm stroke, PT ports, and CA rear clevis mount.
