The AirTAC Airtac SC40 Standard Cylinder SC40X175CA is a genuine double-acting standard air cylinder with a Ø40mm bore and 175mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X175CA is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa and up to 1130 N at the maximum operating pressure of 0.9 MPa. With a 40 mm bore and 175 mm stroke, this model includes a rear single clevis (CA) mount, allowing the cylinder body to pivot during operation for applications requiring angular movement.
This tie-rod cylinder uses a 16 mm diameter piston rod with M12x1.25 male threads and PT1/4 ports. The adjustable air cushion at each end provides a 21 mm deceleration zone, reducing end-of-stroke impact. The total body length is 142 mm, making it a compact solution where a shorter envelope than an ISO 15552 cylinder is needed.

The rear clevis mount allows the SC40X175CA to pivot as it opens and closes small dump gates or chutes on agricultural trailers, handling the 628 N push force needed to move granular materials.
Ideal for pivoting diverter arms on light-duty package conveyors. The 175 mm stroke provides sufficient travel to redirect cartons between lanes, with the clevis absorbing the arc of motion.
Used in welding or assembly fixtures where the cylinder body must swing clear for part loading. The 1130 N maximum force at 0.9 MPa delivers secure clamping pressure for metal fabrication tasks.
For higher force requirements, consider stepping up to the 50 mm bore SC50 series, which provides 982 N of push force at 0.5 MPa. If a lower force and lighter weight are acceptable, the 32 mm bore SC32 series offers 402 N at the same pressure. When replacing an existing cylinder, ensure a match across five critical points: bore (40 mm), stroke (175 mm), PT1/4 port thread, the CA rear clevis mounting style (using accessory F-SC40CA), and the absence of a magnet sensor option. For strokes of 300 mm or longer, evaluate side-load conditions and consider an external guide or guided cylinder to protect the rod bearing from bending moments.
Quick checklist
At the standard 0.5 MPa operating pressure, 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 AirTAC SC series is a tie-rod cylinder with a shorter body length (142 mm body for the 40 mm bore) than an ISO 15552 profile cylinder. It is not dimensionally interchangeable with ISO 15552 standards. It should only replace another AirTAC SC tie-rod cylinder or a compatible tie-rod design matching the exact bore, stroke, port thread, and CA clevis mounting.
