The AirTAC Airtac SC40 Standard Cylinder SC40X400CA is a genuine double-acting standard air cylinder with a Ø40mm bore and 400mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X400CA is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (up to 1130 N at 0.9 MPa), making it a capable mid-range actuator for linear tasks. The 400 mm stroke is paired with a 16 mm diameter piston rod and a 21 mm adjustable air cushion at each end, providing smooth deceleration without external shock absorbers.
This model is configured with a rear single clevis (CA) mount, part F-SC40CA, allowing the cylinder to pivot during operation and simplifying installation in articulated linkages. The standard PT1/4 port thread and TPU seals suit general industrial environments with operating temperatures from -20 to +70 C.

The 400 mm stroke and pivoting CA clevis mount allow this cylinder to swing a gate or diverter arm on a conveyor line, reliably sorting packages with 628 N of force at standard line pressure.
Ideal for operating a welding or assembly fixture clamp. The adjustable cushion protects the fixture from impact at the end of the 400 mm travel, while the clevis mount accommodates the clamp's arcing motion.
Controls a discharge door on a small agricultural hopper or chute. The rear clevis mounting allows the cylinder body to pivot as the door opens and closes through its full 400 mm stroke.
Select the SC40 when your application needs between 500 and 880 N of force at standard plant pressure; if you require more, stepping up to the SC50 provides 982 N push at 0.5 MPa. For this 400 mm stroke, ensure the rod is not subjected to significant side loading—if the load path is not perfectly axial, add an external guide rail or consider a guided cylinder to prevent rod bearing wear and bending. When replacing an existing unit, match bore (40 mm), stroke (400 mm), PT1/4 ports, CA rear clevis mounting, and confirm whether a magnet is needed (this model has no built-in magnet).
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.
This is a direct replacement for another AirTAC SC40 cylinder with the same 400 mm stroke, PT1/4 ports, and rear single clevis (CA) mount. It is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders. Verify your mounting pin size and port thread type before ordering.
