The AirTAC SC50 Standard Cylinder SC50X75TC is a genuine double-acting standard air cylinder with a Ø50mm bore and 75mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X75TC is a double-acting pneumatic cylinder with a 50 mm bore and 75 mm stroke, supplied with a centre trunnion (TC) mount for pivoting applications. At 0.5 MPa it generates 982 N of push force and 825 N on the pull stroke, making it a capable mid-range actuator.
This model uses a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The adjustable air cushion is 21 mm long, and the body length A is 150 mm. The TC mount ships with the TCM1 bracket (order F-SC50TC), allowing the cylinder to swing as the load moves through an arc.

The centre trunnion mount lets the cylinder pivot as it actuates a diverter flap on a conveyor line, directing packages to different lanes.
Ideal for swinging a clamp arm into place on a welding or assembly fixture. The 75 mm stroke provides a compact, fast actuation arc.
Operates a discharge gate on a small hopper or chute. The trunnion mount absorbs the angular movement as the gate opens and closes.
Choose the SC50 for tasks needing around 1000 N at standard line pressure; if your load is lighter, the 40 mm bore (628 N push) can reduce air consumption. For heavier loads, step up to the 63 mm bore (1559 N push).
When replacing an existing cylinder, match five points: 50 mm bore, 75 mm stroke, PT1/4 ports, centre trunnion mount, and no magnet. The SC is a tie-rod cylinder with a shorter body than an ISO 15552 profile—do not assume dimensional interchangeability with ISO 15552 cylinders.
Quick checklist
At 0.7 MPa (7 bar) the push force is 1374 N, and the pull force is 1155 N. The maximum operating force at 0.9 MPa is 1767 N push.
Yes, you can remove the trunnion bracket and install an LB foot mount (F-SC50LB) or FA/FB flange mounts. The cylinder barrel is standard; only the mounting accessory changes.
