The AirTAC Airtac SC50 Standard Cylinder SC50X920TC is a genuine double-acting standard air cylinder with a Ø50mm bore and 920mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X920TC is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1767 N at the 0.9 MPa maximum operating pressure). Its 50 mm bore and 920 mm stroke suit medium-force linear tasks where the cylinder body must pivot during operation, thanks to the factory-fitted centre trunnion mount.
This model uses a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The 21 mm adjustable air cushion at each end decelerates the piston smoothly, and the total extended body length is approximately 1070 mm (150 mm body length A plus the 920 mm stroke). The cylinder operates on 40 µm filtered compressed air from 0.15 to 1.0 MPa and is rated for -20 to +70 °C with its standard TPU seals.

The centre trunnion mount lets the cylinder body swing as it opens and closes a material diverter gate on a packaging conveyor line.
Delivers 1767 N of clamping force at 0.9 MPa for welding fixtures or assembly jigs, with the trunnion absorbing misalignment during the clamping arc.
Operates a pivoting chute or hopper door on a planter or spreader, tolerating dusty conditions with its robust tie-rod construction and filtered air supply.
Choose the SC50 bore when your application needs roughly 980–1770 N of push force. If you require more force, step up to the SC63 bore (1559 N at 0.5 MPa); for a lighter, more compact solution, the SC40 bore provides 628 N at 0.5 MPa. The 920 mm stroke is within the 1200 mm maximum standard stroke for this bore.
At 920 mm stroke, the extended rod is long and can be damaged by side loads. Always guide the load externally with linear rails or rods, or consider a guided cylinder if side forces are unavoidable. For a direct replacement, match five points: 50 mm bore, 920 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting with the TCM1 bracket, and the absence of a magnet. The TC mount (accessory code F-SC50TC, supplied with the TCM1 bracket) allows the cylinder body to pivot, preventing rod bending in swinging applications.
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. The theoretical maximum force at 1.0 MPa is 200 kgf.
Yes, if your existing cylinder is an AirTAC SC50 tie-rod type with a 920 mm stroke, PT1/4 ports, centre trunnion (TC) mount, and no magnet. This model is not dimensionally interchangeable with ISO 15552 cylinders, so verify the body length (150 mm + stroke) and trunnion position before ordering.
