The AirTAC SC50 Standard Cylinder SC50X280SH is a genuine double-acting standard air cylinder with a Ø50mm bore and 280mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X280SH is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa, scaling to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and 280 mm stroke, it uses a 20 mm diameter piston rod with M16x1.5 male threads, and its 21 mm adjustable air cushion extends service life by decelerating the piston smoothly at each end of travel.
This model is configured with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and Viton (FKM) seals (-H) that shift the operating temperature range to 0 to +150 °C, making it suitable for high-temperature or chemically aggressive environments. The body length A is 150 mm, giving a total extended length of approximately 430 mm, and it uses standard PT1/4 ports.

Related variants: SCD (double rod), SCJ (adjustable stroke), SCT (multi-position). Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
With Viton seals rated to 150°C, this cylinder is ideal for clamping, pressing, or ejecting parts in ovens, autoclaves, and foundry equipment where standard seals would degrade.
The built-in magnet allows CMSG or DMSG sensors to clamp directly onto the tie-rod barrel, providing reliable piston position feedback for automated sorting gates or material stops.
Generating up to 1767 N at 0.9 MPa, the SC50X280SH handles medium-duty pressing, riveting, or forming tasks in automated assembly cells where heat and cycle speed are factors.
For applications needing more force, stepping up to the 63 mm bore SC63 series provides 1559 N at 0.5 MPa. If space is a constraint, the 40 mm bore delivers 628 N at the same pressure. This 280 mm stroke is within the 1200 mm maximum standard stroke for bore 50. To ensure a direct replacement, match five key points: 50 mm bore, 280 mm stroke, PT port thread, the built-in magnet sensor capability, and the basic mounting style. For strokes over 300 mm, consider an external guide to protect the rod from bending under side load.
Quick checklist
At the standard operating pressure of 0.7 MPa, the push force is 1374 N and the pull force is 1155 N. The maximum push force at 0.9 MPa is 1767 N. These values are based on the 50 mm bore and 20 mm rod diameter.
No. The SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is a direct match only for another AirTAC SC50 tie-rod cylinder with the same stroke, PT ports, magnet option, and basic mounting.
