The AirTAC SC50 Standard Cylinder SC50X275TC is a genuine double-acting standard air cylinder with a Ø50mm bore and 275mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X275TC is a double-acting tie-rod cylinder delivering a push force of 982 N at 0.5 MPa (up to 1767 N at 0.9 MPa). Its 275 mm stroke is paired with a 20 mm diameter piston rod and PT1/4 ports, making it a capable mid-range actuator for general industrial automation.
This model features a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC50TC), allowing the cylinder to pivot as it strokes. The adjustable air cushion (21 mm length) decelerates the piston smoothly at end-of-travel, reducing impact stress. Operating pressure is 0.15-1.0 MPa with a speed range of 30-800 mm/s.

The centre trunnion mount allows the cylinder body to pivot, ideal for actuating diverter gates on conveyor lines where the cylinder must swing through an arc.
With 982 N of force at standard shop air, this cylinder provides consistent, repeatable clamping pressure for welding jigs and assembly fixtures.
The 275 mm stroke and pivoting trunnion mount suit linear actuation of quarter-turn or gate valves in water treatment and chemical dosing skids.
For applications needing more force, stepping up to the 63 mm bore provides 1559 N push at 0.5 MPa. For lighter, faster loads, the 40 mm bore delivers 628 N. With a 275 mm stroke, ensure the rod is not subjected to significant side loads; if lateral forces are present, an external linear guide or a guided cylinder should be used to prevent rod bearing damage and ensure reliable sealing.
This SC50X275TC is a direct replacement only for another AirTAC SC50 tie-rod cylinder with the same 275 mm stroke, PT1/4 ports, and centre trunnion mount. It is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa (5 bar), 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 at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an equivalent ISO 15552 cylinder. It is only a direct dimensional replacement for another AirTAC SC50 tie-rod cylinder with matching bore, stroke, port thread (PT), and centre trunnion mount.
