The AirTAC SC50 Standard Cylinder SC50X80STC is a genuine double-acting standard air cylinder with a Ø50mm bore and 80mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X80STC is a double-acting pneumatic cylinder delivering a push force of 982 N at 0.5 MPa (1767 N at the 0.9 MPa maximum operating pressure). Its 50 mm bore and 80 mm stroke suit medium-force clamping, pressing, and transfer tasks where a compact tie-rod body is preferred.
This model includes a built-in magnet (-S) for mounting CMSG/DMSG/EMSG sensors directly on the barrel, plus a centre trunnion mount (TC) with the TCM1 bracket (F-SC50TC) that lets the cylinder pivot during actuation. The 20 mm diameter rod, PT1/4 ports, and 21 mm adjustable air cushion provide reliable deceleration without external shock absorbers.

The 80 mm stroke and 982 N push force move tote bins or product diverters on packaging lines, with the TC trunnion mount allowing the cylinder to swing as the transfer arm arcs.
Ideal for pneumatic clamping in machining or welding fixtures. The built-in magnet enables end-of-stroke confirmation via reed sensors to interlock with the machine cycle.
Provides the linear thrust needed to open or close medium-sized quarter-turn valves when paired with a scotch-yoke or rack-and-pinion actuator, with the centre trunnion absorbing reaction torque.
For higher force at the same pressure, step up to the 63 mm bore SC63 series (1559 N push at 0.5 MPa); for a lighter, faster actuator, the 40 mm bore SC40 delivers 628 N. Always match replacement cylinders on all five key points: 50 mm bore, 80 mm stroke, PT port thread, TC centre-trunnion mounting with magnet (-S), and tie-rod body style.
At 80 mm stroke, side loading is typically minimal, but ensure the rod is aligned with the load path. If the application involves off-axis forces, an external guide rail is recommended to protect the rod bearing and piston seals from premature wear.
Quick checklist
At the standard 0.5 MPa operating pressure, it generates 982 N extending (push) and 825 N retracting (pull). At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder, so mounting dimensions are not interchangeable. This model directly replaces another AirTAC SC50X80 with a centre trunnion and magnet, provided the port thread (PT) matches.
