The AirTAC SC50 Standard Cylinder SC50X55H is a genuine double-acting standard air cylinder with a Ø50mm bore and 55mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X55H is a double-acting tie-rod cylinder engineered for high-temperature duty, using Viton (FKM) seals to operate reliably from 0 to +150 °C. With a 50 mm bore and 55 mm stroke, it generates 982 N of push force at 0.5 MPa and up to 1767 N at 0.9 MPa, driven by a 20 mm diameter piston rod.
This model features a body length A of 150 mm, yielding a compact extended length of approximately 205 mm. The adjustable pneumatic cushion (21 mm) decelerates the piston smoothly at stroke end, and the PT1/4 port thread ensures straightforward pneumatic connection. This is a genuine AirTAC cylinder built for hot or aggressive environments.

Related variants: SCD (double rod), SCJ (adjustable stroke), SCT (multi-position). Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
Viton seals allow this cylinder to function in ovens, autoclaves, or near heat sources up to 150 °C, where standard seals would degrade.
Delivers 1767 N at 0.9 MPa for holding molds or tooling in heated presses and injection molding auxiliary equipment.
Suitable for environmental test chambers and lab automation requiring consistent pneumatic force under elevated temperatures.
Choose the SC50X55H when your application demands a heat-resistant actuator with moderate force. If you need higher force, stepping up to the 63 mm bore provides 1559 N push at 0.5 MPa; for lighter, faster moves, the 40 mm bore offers 628 N. Always match replacement cylinders on five points: bore, stroke, port thread (PT), mounting accessory, and magnet option.
For strokes above 300 mm, side-load bending on the rod bearing becomes a concern—consider an external guide or a guided cylinder. This 55 mm stroke is well within standard range and does not require additional rod support for axial loads.
Quick checklist
At 0.5 MPa, 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 ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC tie-rod cylinder with matching bore, stroke, PT port, and basic mounting.
