The AirTAC Airtac SC50 Standard Cylinder SC50X950TC is a genuine double-acting standard air cylinder with a Ø50mm bore and 950mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X950TC 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 950 mm stroke, this model is suited for long linear movements in material handling and automation where a centre pivot mount is required.
This unit features a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The integrated TC centre trunnion mount (supplied with the TCM1 bracket, order code F-SC50TC) allows the cylinder body to pivot, accommodating swinging loads. The adjustable air cushion at each end, with a 21 mm cushion length, decelerates the piston smoothly to reduce end-of-stroke impact.

Moves components 950 mm between conveyor lines or workstations. The centre trunnion mount allows the cylinder to pivot, aligning with changing pick-and-place trajectories.
Operates a swinging clamp arm in welding or assembly jigs. The 1767 N force at 0.9 MPa provides a firm hold, while the trunnion mount absorbs the rotational movement.
Actuates a diverter gate on a long chute in agricultural processing. The 950 mm stroke provides the necessary travel, and the pivot mount handles the arcing motion of the linkage.
Select the SC50 bore when your application requires between 825 N (pull) and 982 N (push) at 0.5 MPa. If your force requirement is lower, stepping down to the SC40 bore (628 N push at 0.5 MPa) can reduce air consumption. For higher force, the SC63 bore provides 1559 N push at the same pressure. At a 950 mm stroke, ensure the rod is protected from side loading; an external guide or rod support is recommended to prevent bending and premature bearing wear. When replacing this cylinder, match the 50 mm bore, 950 mm stroke, PT port thread, and the TC centre trunnion mounting configuration.
Quick checklist
At the standard operating pressure of 0.5 MPa, this cylinder provides 982 N of force when extending (push) and 825 N when retracting (pull). At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N.
The TC mount is a trunnion pin integrated into the cylinder body. It is supplied with the TCM1 trunnion bracket (order code F-SC50TC) which bolts to your machine frame, allowing the cylinder to pivot freely. This is essential for applications where the load moves through an arc.
