About the Airtac SC50 Standard Cylinder SC50X260STC
The SC50X260STC is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at the maximum operating pressure of 0.9 MPa). Its 20 mm diameter piston rod and 260 mm stroke make it a solid choice for medium-duty linear tasks where a pivoting mount is required.
This configuration includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and is supplied with a centre trunnion (TC) and TCM1 bracket (F-SC50TC) for swinging loads. The tie-rod construction keeps the overall length compact at 410 mm (150 mm body + 260 mm stroke), and the 21 mm adjustable air cushion at each end ensures quiet, controlled deceleration.

Where the Airtac SC50 Standard Cylinder SC50X260STC Is Used
Part Diverter Gates
The centre trunnion mount allows the cylinder body to pivot, making it ideal for actuating diverter gates on conveyor lines where a 260 mm stroke provides ample travel.
Clamping & Welding Fixtures
With 982 N of clamping force at standard line pressure and sensor confirmation via the built-in magnet, this cylinder reliably secures parts in automated welding and assembly jigs.
Hopper & Chute Control
The 50 mm bore provides robust force to open and close discharge chutes on agricultural hoppers, with the trunnion mount allowing the cylinder to swing freely during actuation.
Is the Airtac SC50 Standard Cylinder SC50X260STC the Right Cylinder?
For applications needing more force, stepping up to the 63 mm bore provides 1559 N at 0.5 MPa. If space is tight and less force is acceptable, the 40 mm bore offers 628 N. When replacing an existing cylinder, match five points: 50 mm bore, 260 mm stroke, PT port thread, centre trunnion (TC) mounting, and the built-in magnet for sensors.
With a 260 mm stroke, side loading on the 20 mm rod is a key consideration. Ensure the load is guided externally or use a guided cylinder variant if significant lateral forces are present, as unsupported rod bending can damage the bearing and seals.
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 SC50X260STC FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. The maximum push force at the 0.9 MPa operating limit is 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No, the SC50X260STC is a double-acting cylinder and will not hold position if pressure is exhausted or the valve is centered. The piston can drift or drop. For load holding without live pressure, you must add a pilot-operated check valve or an external mechanical rod lock.
