About the Airtac SC50 Standard Cylinder SC50X100STCN
The SC50X100STCN is a double-acting pneumatic cylinder delivering 982 N of push force and 825 N of pull force when operated at 0.5 MPa. With a 100 mm stroke and a 20 mm diameter piston rod, this model is well-suited for medium-duty clamping, pressing, and material handling tasks that require consistent linear motion.
This configuration includes a built-in magnet for mounting CMSG/DMSG/EMSG sensors directly onto the tie-rod barrel, enabling precise end-of-stroke detection. The centre trunnion mount (TC) with the included TCM1 bracket allows the cylinder to pivot during operation, making it ideal for swinging or articulating loads. NBR seals are fitted, and the body length A is 150 mm.

Where the Airtac SC50 Standard Cylinder SC50X100STCN Is Used
Part Diverting
The pivoting trunnion mount and sensor-ready design make this cylinder a reliable choice for actuating gates or diverters on conveyor lines, where end-of-stroke feedback is required for sequencing.
Clamping Fixtures
Delivers nearly 1000 N of clamping force at standard shop air pressure, ideal for holding workpieces in CNC machining centres or welding jigs where the cylinder body needs to swing clear for loading.
Agricultural Equipment
The NBR seals and robust tie-rod construction handle dusty conditions, while the trunnion mount allows for the angular movement needed in chute controls or linkage actuation on farm machinery.
Is the Airtac SC50 Standard Cylinder SC50X100STCN the Right Cylinder?
For applications needing more force, stepping up to a 63 mm bore provides 1559 N of push force at the same 0.5 MPa pressure. If space is a constraint and less force is acceptable, the 40 mm bore offers 628 N. For this 100 mm stroke, side loading is a primary concern; always guide the load externally if lateral forces are present to prevent premature rod bearing wear and seal failure.
When replacing this cylinder, match five key points: the 50 mm bore, 100 mm stroke, PT port thread, centre trunnion (TC) mounting accessory, and the built-in magnet (-S) for sensor compatibility. This ensures a direct dimensional and functional swap.

- ✓ 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 SC50X100STCN FAQ
At the standard operating pressure of 0.7 MPa, the push force is 1374 N and the pull force is 1155 N. The maximum theoretical force at 1.0 MPa is 200 kgf (1960 N). Always apply a safety factor for dynamic loads.
Yes. The 'TC' suffix indicates it is supplied with a centre trunnion mount and the TCM1 bracket (accessory code F-SC50TC). This allows the cylinder body to pivot, which is essential for applications where the load follows an arc. The trunnion pin is the centre of rotation.
