The AirTAC Airtac SC40 Standard Cylinder SC40X90 is a genuine double-acting standard air cylinder with a Ø40mm bore and 90mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X90 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering 628 N of push force at 0.5 MPa and up to 1130 N at 0.9 MPa. With a 40 mm bore and 90 mm stroke, it suits short-to-medium linear moves in clamping, pressing, and ejector stations.
This model features a 16 mm diameter piston rod with M12x1.25 male threads and PT1/4 ports. The body length A is 142 mm, giving a total extended length of approximately 232 mm. An adjustable air cushion softens end-of-stroke impact over the final 21 mm of travel.

628 N at 0.5 MPa provides ample force for pressing bushings, pins, or connectors into housings on automated assembly lines.
Short 90 mm stroke quickly extends a gate or diverter arm to separate conforming and non-conforming parts on a conveyor.
Delivers consistent clamping force for workholding in CNC machining, welding jigs, and test fixtures.
For applications needing more force, the SC50X90 steps up to 982 N push at 0.5 MPa. If a shorter stroke is preferred, the SC40X75 or SC40X80 are standard alternatives. Always match bore, stroke, PT1/4 port thread, and mounting accessory when replacing an existing cylinder.
At 90 mm stroke, side-load risk is low, but if the rod sees off-axis forces, use an external linear guide or switch to a guided cylinder to protect the rod bearing and piston seals.
Quick checklist
At 0.7 MPa (7 bar) the SC40X90 produces 879 N of push force. The pull force on the return stroke is 528 N at 0.5 MPa due to the rod area.
This basic SC40X90 model does not include a built-in magnet. To use CMSG/DMSG/EMSG sensors, order the SC40X90-S variant, which adds a magnetic piston ring.
