The AirTAC SC50 Standard Cylinder SC50X750STC is a genuine double-acting standard air cylinder with a Ø50mm bore and 750mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X750STC is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and a 750 mm stroke, this model features a 20 mm diameter piston rod and an adjustable air cushion of 21 mm to decelerate the piston smoothly at the end of travel.
This configuration includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for non-contact position sensing. The TC suffix designates a centre trunnion mount, supplied with the TCM1 bracket (F-SC50TC), which enables the cylinder to pivot for swinging load applications. The body length A is 150 mm, making the total extended length approximately 900 mm.

The pivoting action of the centre trunnion mount and the 750 mm stroke make this cylinder ideal for actuating diverter gates on conveyor systems, with magnetic sensors confirming gate position.
Provides consistent clamping force up to 1767 N for holding parts in welding fixtures. The built-in magnet allows for sensor feedback to ensure the clamp is fully engaged before the cycle starts.
Suitable for push-off or sorting mechanisms in warehouses, where the trunnion mount allows the cylinder to follow the arc of a pusher arm, reducing stress on the rod.
For applications requiring slightly less force, consider stepping down to the 40 mm bore SC40 series, which provides 628 N of push force at 0.5 MPa. If higher force is needed, the 63 mm bore SC63 series offers 1559 N at the same pressure. For this 750 mm stroke, ensure that side loads are managed; long, unsupported strokes with a 20 mm rod are susceptible to bending under lateral forces. An external guide or a guided cylinder should be used to protect the rod bearings and seals. When replacing this cylinder, match the 50 mm bore, 750 mm stroke, PT port thread, centre trunnion (TC) mount with the F-SC50TC bracket, and the integrated magnet for sensors.
Quick checklist
The theoretical push force is 982 N at 0.5 MPa, 1374 N at 0.7 MPa, and 1767 N at 0.9 MPa. The pull force on the return stroke is 825 N at 0.5 MPa due to the 20 mm piston rod area. These forces are based on a standard operating pressure range of 0.15–1.0 MPa.
No. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than an ISO 15552 profile cylinder and is not dimensionally interchangeable. A direct replacement must be another AirTAC SC50 tie-rod cylinder with a 750 mm stroke, PT ports, centre trunnion mount, and a magnetic piston.
