The AirTAC SC50 Standard Cylinder SC50X55STC is a genuine double-acting standard air cylinder with a Ø50mm bore and 55mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X55STC is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at 0.9 MPa. With a 50 mm bore and 55 mm stroke, it features a 20 mm diameter piston rod and an adjustable air cushion for smooth deceleration.
This configuration includes a built-in magnet (-S) for mounting CMSG/DMSG/EMSG sensors directly on the tie-rod barrel, and a centre trunnion mount (TC) with the TCM1 bracket for pivoting applications. The standard PT ports and TPU seals suit operating temperatures from -20 to +70 °C.

The 55 mm stroke and 982 N force at 0.5 MPa provide secure, repeatable clamping for machining and assembly fixtures.
The centre trunnion mount allows the cylinder body to pivot, making it suitable for actuating diverter gates on conveyor lines.
With the built-in magnet for end-of-stroke sensing, this cylinder reliably drives pivoting linkages in automated machinery.
For higher force, step up to the 63 mm bore (1559 N at 0.5 MPa); for a lighter, more compact build, the 40 mm bore offers 628 N. The centre trunnion mount allows the cylinder to pivot during operation, ideal for swinging loads. For a direct replacement, match the 50 mm bore, 55 mm stroke, PT port thread, TC mount with TCM1 bracket, and the built-in magnet for sensor compatibility.
Quick checklist
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N.
Yes, the -S suffix indicates a built-in magnet, so you can directly clamp CMSG, DMSG, or EMSG reed or solid-state sensors onto the cylinder barrel for position feedback.
