About the Airtac SC50 Standard Cylinder SC50X325STC
The SC50X325STC is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). Its 325 mm stroke and 20 mm diameter piston rod suit medium-reach clamping, pressing, and material-handling tasks where a compact tie-rod design is preferred.
This model includes a built-in magnet (-S) for mounting CMSG/DMSG/EMSG sensors directly on the barrel, plus a centre trunnion (TC) mount with TCM1 bracket for pivoting applications. The body length A is 150 mm, and the adjustable air cushion (21 mm) decelerates the piston quietly at end-of-stroke.

Where the Airtac SC50 Standard Cylinder SC50X325STC Is Used
Part Transfer & Sorting
Pivots a diverter gate on a conveyor line, using the centre trunnion mount to swing the cylinder body while sensors confirm gate position.
Light Assembly Press
Applies up to 1767 N of insertion force at 0.9 MPa for pressing bushings or connectors into housings, with magnetic sensors verifying full stroke.
Clamping Fixture Actuation
Operates a pivoting clamp arm on a welding or machining fixture. The trunnion mount allows the cylinder to follow the clamp's arc, reducing rod side-load.
Is the Airtac SC50 Standard Cylinder SC50X325STC the Right Cylinder?
For higher force, step up to the 63 mm bore (1559 N at 0.5 MPa); for a lighter, faster actuator, the 40 mm bore provides 628 N. This 325 mm stroke is within the 1200 mm maximum standard stroke for bore 50. When replacing an existing unit, match five points: 50 mm bore, 325 mm stroke, PT port thread, centre trunnion (TC) mounting, and the built-in magnet (-S).
At this stroke length, avoid placing side loads on the unsupported rod. If the application applies lateral force, pair the cylinder with an external linear guide or consider a guided cylinder to prevent rod bending and premature bearing wear.
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 SC50X325STC FAQ
At 0.5 MPa the push force is 982 N and pull force is 825 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder, so mounting dimensions and body length are not interchangeable. It is a direct replacement only for another AirTAC SC50 tie-rod cylinder with matching stroke, port, magnet, and centre trunnion mount.
