The AirTAC Airtac SC40 Standard Cylinder SC40X210 is a genuine double-acting standard air cylinder with a Ø40mm bore and 210mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X210 is a double-acting tie-rod cylinder delivering 628 N of push force when supplied with 0.5 MPa air pressure. With a 40 mm bore and 210 mm stroke, it uses a 16 mm diameter piston rod and PT1/4 ports for straightforward pneumatic integration.
At the maximum operating pressure of 0.9 MPa, this cylinder generates 1130 N of thrust. The body length A is 142 mm, giving a total extended length of approximately 352 mm. Its adjustable air cushion softens end-of-stroke impact, protecting machinery during high-cycle operation.

Provides the 628 N push force needed to raise and lower stop gates on light-duty package conveyors, reliably halting totes and cartons at sorting stations.
Used in woodworking and light metalworking jigs where a 210 mm stroke and 16 mm rod provide ample reach and clamping force for securing workpieces during drilling or routing.
Operates louvre dampers in agricultural ventilation systems, using its double-acting control to precisely modulate airflow in livestock or greenhouse environments.
For applications needing more force, stepping up to the 50 mm bore SC50 series provides 982 N of push at 0.5 MPa. If space is a constraint and less force is acceptable, the 32 mm bore SC32 offers 402 N at the same pressure. This 210 mm stroke is within the 1200 mm maximum standard stroke for the 40 mm bore.
When replacing an existing cylinder, match five key points: 40 mm bore, 210 mm stroke, PT1/4 port thread, basic (no mounting accessory) configuration, and no built-in magnet. This model is a standard SC tie-rod cylinder and is dimensionally interchangeable only with another AirTAC SC40 of the same stroke and port type.
Quick checklist
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, push force increases to 879 N. The maximum operating push force at 0.9 MPa is 1130 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable with ISO 15552 types. It directly replaces another AirTAC SC40 cylinder with the same stroke, port thread, and mounting configuration.
