The AirTAC Airtac SC40 Standard Cylinder SC40X75CA 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 SC40X75CA is a tie-rod double-acting pneumatic cylinder with a 40 mm bore and 75 mm stroke, factory-configured with a rear single clevis (CA) mount for pivoting applications. At 0.5 MPa air pressure it generates 628 N of push force and 528 N pull force, making it a capable mid-range actuator for medium-duty linear tasks.
This model uses a 16 mm diameter piston rod with an M12x1.25 rod thread and PT1/4 pneumatic ports. The adjustable air cushion at both ends (21 mm cushion length) decelerates the piston smoothly, reducing end-of-stroke impact. The body length A is 142 mm, giving a total extended length of approximately 217 mm. Operating pressure is 0.15-1.0 MPa with a standard speed range of 30-800 mm/s.

The 628 N push force at 0.5 MPa provides ample clamping pressure for workholding jigs, welding fixtures, and assembly stations where the cylinder body pivots on a rear clevis.
With a rear clevis mount, this cylinder can pivot to actuate diverter gates on packaging or sorting conveyors, directing parts between lanes with a 75 mm stroke.
Ideal for agricultural machinery linkages and lever mechanisms where a clevis-mounted cylinder must swing freely. The TPU seals handle dusty environments within the -20 to +70 °C range.
The SC40X75CA suits applications needing a pivoting cylinder body, thanks to the rear single clevis (part code F-SC40CA) which allows the cylinder to swing through an arc. If your load requires higher force, step up to the SC50 bore (982 N push at 0.5 MPa); for a lighter, more compact solution, the SC32 bore provides 402 N.
To replace an existing cylinder, match five points: 40 mm bore, 75 mm stroke, PT1/4 port thread, rear CA clevis mounting, and no magnet. This tie-rod cylinder is shorter than an ISO 15552 profile cylinder and is not dimensionally interchangeable with that standard.
Quick checklist
At 0.5 MPa (5 bar) it produces 628 N pushing and 528 N pulling. At the maximum operating pressure of 0.9 MPa, push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
The CA suffix means this cylinder ships with a rear single clevis bracket (F-SC40CA). You can remove it for basic tie-rod mounting, or order the base model SC40X75 if a clevis is not required. The clevis allows the cylinder body to pivot during operation.
