The AirTAC Airtac SC50 Standard Cylinder SC50X950SH is a genuine double-acting standard air cylinder with a Ø50mm bore and 950mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X950SH is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and a long 950 mm stroke, it features a 20 mm diameter piston rod and an adjustable air cushion of 21 mm to decelerate the piston smoothly at the end of travel.
This model is configured with a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and high-temperature Viton seals (-H suffix) that shift the operating range to 0 to +150 °C. The body length A is 150 mm, giving a total extended length of approximately 1100 mm. Ports are standard PT1/4.

Related variants: SCD (double rod), SCJ (adjustable stroke), SCT (multi-position). Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
The Viton seals withstand ambient temperatures up to 150 °C, making this cylinder ideal for actuating platens or ejector mechanisms in heated laminating and forming presses.
With a 950 mm stroke and sensor-ready magnet, it accurately pushes or pulls components across wide conveyor gaps, with end-of-stroke confirmation via reed switches.
Operates reliably in high-temperature environments to open and close small sliding gates or dampers, where standard seals would degrade quickly.
For a 50 mm bore at 0.5 MPa, the 982 N push force suits medium automation tasks. If your load requires more force, stepping up to a 63 mm bore provides 1559 N at the same pressure. For lighter, faster cycles, the 40 mm bore delivers 628 N. At a 950 mm stroke, the 20 mm rod is long and unsupported; any side load will cause bending stress on the rod bearing. Use an external linear guide or a guided cylinder to protect the rod and seals from premature wear.
This genuine AirTAC SC cylinder is a direct replacement only for another AirTAC SC50 tie-rod cylinder with matching 950 mm stroke, PT1/4 ports, a built-in magnet, and Viton seals. It is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.7 MPa (7 bar) supply pressure, the theoretical push force on the 50 mm bore piston is 1374 N. The pull force on the retract stroke is 825 N at 0.5 MPa, reduced by the 20 mm rod area.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder of the same bore and stroke. It is not dimensionally interchangeable. It is a direct match only for another AirTAC SC50 tie-rod cylinder with the same stroke, port thread, magnet, and Viton seal configuration.
