The AirTAC Airtac SC40 Standard Cylinder SC40X310 is a genuine double-acting standard air cylinder with a Ø40mm bore and 310mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X310 is a double-acting tie-rod cylinder delivering 628 N of push force when supplied with 0.5 MPa air pressure, rising to 1130 N at the maximum operating pressure of 0.9 MPa. Its 16 mm diameter piston rod and 21 mm adjustable air cushion make it a reliable workhorse for medium-stroke linear tasks.
With a body length of 142 mm, the total extended length for this 310 mm stroke configuration is approximately 452 mm. The PT1/4 ports and M12x1.25 rod thread provide straightforward pneumatic connections, while the standard TPU seals ensure smooth operation within a -20 to +70 °C temperature range.

Actuates a gate or pusher arm on a conveyor line, sorting cartons with a 310 mm reach. The 628 N force at standard line pressure easily handles medium-weight parcel diversion.
Provides the holding force for a welding or assembly jig. The adjustable cushion decelerates the clamp arm smoothly, preventing impact marks on delicate workpieces.
Opens and closes a discharge door on a seed or grain hopper. The tie-rod construction and NBR/TPU seals stand up to dusty agricultural environments.
For applications needing more force, stepping up to the 50 mm bore SC50 series provides 982 N of push force at 0.5 MPa. If space is a constraint, the 32 mm bore SC32 delivers 402 N at the same pressure. When replacing an existing cylinder, match five points exactly: 40 mm bore, 310 mm stroke, PT1/4 port thread, basic mounting (no accessory bracket), and confirm whether a magnet is required.
At 310 mm of stroke, the 16 mm rod is cantilevered significantly when fully extended. Avoid direct side loads on the rod end; if the load path is not perfectly axial, use an external linear guide or a guided cylinder to prevent rod bending and premature bearing wear.
Quick checklist
At 0.5 MPa, the theoretical push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder and its body length is shorter than an ISO 15552 profile cylinder. It is not dimensionally interchangeable with ISO 15552. Only use it to replace another AirTAC SC tie-rod cylinder with identical bore, stroke, port thread, and mounting.
