About the Airtac SC50 Standard Cylinder SC50X225TC
The SC50X225TC is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (up to 1767 N at 0.9 MPa), built around a 20 mm diameter piston rod. With a 225 mm stroke and a centre trunnion (TC) mount, it is designed to pivot freely as it extends and retracts, making it ideal for articulated machine sections.
The cylinder body measures 150 mm (dimension A), giving an extended length of approximately 375 mm. It features an adjustable air cushion (21 mm length) at both ends to decelerate the piston smoothly, reducing end-of-stroke impact. The standard PT1/4 ports and M16x1.5 rod thread ensure straightforward pneumatic connections and tooling attachment.

Where the Airtac SC50 Standard Cylinder SC50X225TC Is Used
Part Diverter Gates
The centre trunnion mount allows this cylinder to pivot, making it perfect for actuating diverter gates on conveyor lines where a mid-stroke swing is required.
Clamping & Welding Fixtures
Delivers a controlled 982 N clamping force at standard line pressure, with an adjustable cushion to gently close tooling arms without slamming.
Agricultural Implement Control
Provides reliable linear motion for chute controls or linkage actuation on farm machinery, operating within a -20 to +70 °C temperature range with TPU seals.
Is the Airtac SC50 Standard Cylinder SC50X225TC the Right Cylinder?
The SC50 bore sits between the lighter SC40 (628 N at 0.5 MPa) and the more powerful SC63 (1559 N at 0.5 MPa). If your load requires a mid-range force with a pivoting mount, this model is a strong fit. For strokes over 300 mm, consider an external guide to protect the 20 mm rod from side-load bending.
To ensure a direct replacement, match five key points: 50 mm bore, 225 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting style, and the absence of a built-in magnet. The TC mount includes the TCM1 trunnion bracket (order as assembly F-SC50TC) and allows the cylinder body to swing during operation.
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 SC50X225TC FAQ
At 0.5 MPa, the cylinder produces 982 N extending (push) and 825 N retracting (pull). At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N.
No. The SC50X225TC is a double-acting cylinder and will drift or drop if pressure is lost or the directional valve is centred. To hold a position without live pressure, you must add a pilot-operated check valve or an external mechanical rod lock.
