The AirTAC Airtac SC40 Standard Cylinder SC40X315S is a genuine double-acting standard air cylinder with a Ø40mm bore and 315mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X315 is a double-acting tie-rod cylinder delivering 628 N push and 528 N pull at 0.5 MPa, scaling to 1130 N push at 0.9 MPa. Its 315 mm stroke is well within the 1200 mm maximum standard stroke for the 40 mm bore, making it a readily available standard configuration.
Built with a 16 mm diameter piston rod and M12x1.25 rod thread, this cylinder includes a 21 mm adjustable air cushion at each end to decelerate the piston smoothly. The body length A is 142 mm, giving a total extended length of approximately 457 mm. PT1/4 ports and TPU seals with a -20 to +70 °C operating range complete the standard specification.

The 315 mm stroke and 628 N push force at 0.5 MPa suit medium-reach diverter gates on packaging conveyors, reliably pushing cartons onto parallel lanes.
Ideal for pneumatic clamping stations in woodworking or light metal fabrication, where the 40 mm bore provides ample holding force without overstressing the fixture.
Operates sliding gates on small aggregate or grain hoppers. The tie-rod construction handles dusty environments, and the adjustable cushion softens the gate impact at stroke end.
Choose the SC40 bore when your application needs 500-630 N of push force at standard plant pressure. If you require more force, step up to the SC50 bore which provides 982 N push at 0.5 MPa; for a lighter, more compact solution, the SC32 bore offers 402 N push at 0.5 MPa. Always match the bore, 315 mm stroke, PT1/4 port thread, and basic mounting when replacing an existing unit.
At 315 mm stroke, the 16 mm rod is adequately supported for axial loads, but any side loading must be managed with external linear guides. The SC cylinder is not a guided actuator; bending moments on the rod can cause premature bearing wear and seal failure.
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, push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
This standard SC40X315 model does not include a built-in magnet. To use CMSG/DMSG/EMSG reed or solid-state sensors, order the -S magnet variant (SC40X315-S). The sensor then clamps directly onto the tie-rod barrel.
