The AirTAC Airtac SC40 Standard Cylinder SC40X75H is a genuine double-acting standard air cylinder with a Ø40mm bore and 75mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X75H is a double-acting pneumatic cylinder with a 40 mm bore and 75 mm stroke, factory-fitted with Viton (FKM) seals for reliable operation in high-temperature environments up to 150°C. With a 16 mm diameter piston rod and PT1/4 ports, it delivers a push force of 628 N at 0.5 MPa and can reach 1130 N at 0.9 MPa.
This tie-rod cylinder features an adjustable air cushion (21 mm length) at both ends to decelerate the piston smoothly, reducing end-of-stroke impact. The body length A is 142 mm, giving a total extended length of approximately 217 mm. The SC40X75H is a genuine AirTAC pneumatic component, built for consistent performance in hot or demanding industrial settings.

Viton seals allow this cylinder to operate in ambient temperatures up to 150°C, making it suitable for pressing, drying, or autoclave equipment where standard seals would degrade.
The 75 mm stroke and 628 N push force at 0.5 MPa provide crisp, repeatable motion for diverting parts on a conveyor line, even in warm factory conditions.
Delivers up to 1130 N of clamping force at 0.9 MPa. The double-acting design ensures positive retraction, ideal for automated welding or assembly jigs.
For applications needing more force, the 50 mm bore SC50 series provides 982 N push at 0.5 MPa. If a shorter, lighter actuator is sufficient, the 32 mm bore SC32 offers 402 N. Ensure the replacement cylinder matches all five key points: 40 mm bore, 75 mm stroke, PT1/4 port thread, basic mount (no accessory), and no magnet. The Viton seal variant is essential for ambient temperatures above 70°C.
At 75 mm stroke, the 16 mm rod is well-supported within the standard stroke range, but any side load should still be managed with an external guide to protect the rod bearing and seals from premature wear.
Quick checklist
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
No. The SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 cylinder of the same bore and stroke, so it is not dimensionally interchangeable. It replaces another AirTAC SC40 cylinder with the same bore, stroke, port thread, and mounting.
