The AirTAC SC50 Standard Cylinder SC50X900H is a genuine double-acting standard air cylinder with a Ø50mm bore and 900mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X900H is a double-acting single-rod pneumatic cylinder engineered for high-temperature duty, with a 50 mm bore and 900 mm stroke. Its Viton (FKM) seals shift the operating temperature range to 0–150 °C, making it suitable for autoclaves, drying ovens, and foundry equipment where standard polyurethane would degrade. At 0.5 MPa air pressure the cylinder delivers 982 N of push force, and at the maximum operating pressure of 0.9 MPa it generates 1767 N.
This model uses a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The adjustable air cushion at each end (21 mm cushion length) decelerates the piston smoothly, reducing end-of-stroke impact. The body length A is 150 mm, giving a total extended length of approximately 1050 mm. As a tie-rod cylinder, the SC50 is shorter than an equivalent ISO 15552 profile cylinder and is not dimensionally interchangeable with that standard.

Operates reliably in autoclave lid actuation, drying oven door control, and hot stamping presses where ambient temperatures reach 150 °C, thanks to the Viton (FKM) seal package.
The 900 mm stroke pushes or pulls parts across wide conveyor gaps or between process stations, delivering 1767 N of force at 0.9 MPa to move heavy tooling or workpieces.
Withstands radiant heat and aggressive airborne contaminants in foundry shakeout, glass forming, and ceramic kiln machinery, maintaining seal integrity where standard NBR or TPU would fail.
Choose the SC50X900H when your application demands a 900 mm stroke and continuous exposure to temperatures up to 150 °C. If the 982 N push force at 0.5 MPa is marginal, stepping up to the 63 mm bore (SC63 series) provides 1559 N at the same pressure, while the 40 mm bore (SC40) offers 628 N for lighter, more compact installations. The 900 mm stroke is within the 1200 mm maximum standard stroke for the 50 mm bore.
For a 900 mm stroke, the long unsupported piston rod is vulnerable to bending under side loads. Always guide the load externally with linear rails or rods, or consider an AirTAC guided-cylinder assembly, to protect the rod bearing and piston seals from premature wear. When replacing an existing cylinder, match five points: 50 mm bore, 900 mm stroke, PT1/4 port thread, basic (no mounting accessory), and the high-temperature Viton seal designation (H).
Quick checklist
At 0.7 MPa operating pressure, the SC50X900H produces 1374 N of push force on the piston and 825 N of pull force on the retract stroke. The maximum push force at 0.9 MPa is 1767 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. Match it only with another AirTAC SC50 tie-rod cylinder of the same bore, stroke, port thread, and seal material.
