The AirTAC SC50 Standard Cylinder SC50X750TC 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 AirTAC SC50X750TC is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and a 20 mm diameter piston rod featuring M16x1.5 male threads, this actuator is built for robust linear motion tasks.
Configured with a centre trunnion (TC) mount, the cylinder is supplied complete with the TCM1 bracket (F-SC50TC), allowing it to pivot freely to accommodate angular misalignment in swinging loads. The 750 mm stroke is well within the 1200 mm maximum standard stroke for this bore size, and the adjustable air cushion at each end provides smooth deceleration over a 21 mm cushion length.

The pivoting action of the trunnion mount combined with 1767 N of clamping force at 0.9 MPa makes this cylinder suitable for welding fixtures and assembly jigs that require the actuator to swing clear for part loading.
Ideal for actuating diverter gates on material handling lines. The trunnion mount absorbs the arc of motion, while the 750 mm stroke provides ample reach to redirect packages or product flow.
Provides reliable linear actuation for chute controls and bin gates on harvesters or spreaders. The centre pivot mounting handles the constant vibration and angular movement common in mobile equipment.
Selecting the SC50X750TC means matching a specific mounting requirement. The centre trunnion allows the cylinder body to pivot, making it ideal for applications where the load moves through an arc. If your application involves a purely linear push with no angular movement, consider stepping down to a basic or foot-mounted SC50 variant. For higher force requirements, the SC63 bore provides 1559 N of push at 0.5 MPa.
For a 750 mm stroke, ensure the rod is adequately supported against side loads. While the 20 mm rod is robust, long extensions under lateral force can cause bending or uneven seal wear. If the load is not guided externally, consider adding an external guide rail or switching to a guided cylinder to protect the rod bearings and seals.
Quick checklist
At the standard operating pressure of 0.5 MPa (approx. 73 psi), the cylinder pushes with 982 N. At the maximum rated pressure of 0.9 MPa, the extending force is 1767 N. The retracting (pull) force at 0.5 MPa is 825 N due to the area occupied by the 20 mm rod.
No, the AirTAC SC series is a tie-rod design and is physically shorter than a standard ISO 15552 profile cylinder. Direct interchangeability is only guaranteed with another AirTAC SC tie-rod cylinder of matching 50 mm bore, 750 mm stroke, PT port thread, and TC centre trunnion mount.
