The AirTAC Airtac SC40 Standard Cylinder SC40X970S is a genuine double-acting standard air cylinder with a Ø40mm bore and 970mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X970S is a double-acting tie-rod cylinder with a 40 mm bore and a long 970 mm stroke, equipped with a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors. At 0.5 MPa it provides 628 N of push force, and at the maximum operating pressure of 0.9 MPa it reaches 1130 N, driven through a 16 mm diameter piston rod.
With a body length A of 142 mm, the total extended length is approximately 1112 mm. The adjustable pneumatic cushion (21 mm) decelerates the piston at stroke end to reduce impact. This model uses a PT1/4 port and an M12x1.25 rod thread, and operates on filtered air within a -20 to +70 °C range with its standard TPU seals.

The 970 mm stroke moves components between distant conveyor stations, with the built-in magnet allowing end-of-stroke position sensing for automated line control.
Operates a tall diverter gate in a material handling system, using its 628 N push force at 0.5 MPa to reliably direct packages down different lanes.
Provides a long vertical push stroke for lifting bins or totes in a warehouse automation cell, where sensor feedback confirms full extension and retraction.
This 40 mm bore cylinder suits applications needing up to 628 N at 0.5 MPa. If your load requires more force, stepping up to a 50 mm bore (982 N at 0.5 MPa) is a direct option. For a lighter, more compact solution, a 32 mm bore (402 N at 0.5 MPa) may suffice.
For a 970 mm stroke, side loads and rod deflection are critical concerns. An external guide or a guided cylinder is strongly recommended to protect the rod bearing from bending moments. When replacing, match five points: 40 mm bore, 970 mm stroke, PT1/4 port thread, the basic mounting configuration, and the -S magnet option for sensor compatibility.
Quick checklist
At 0.7 MPa, the push force is 879 N. The pull force at the same pressure is lower due to the rod area and is 528 N at 0.5 MPa. Always design for the lower pull force if the cylinder works in both directions.
No. The SC series is a tie-rod cylinder that is shorter in overall length than an ISO 15552 profile cylinder, so dimensional interchangeability is not guaranteed. It is a direct replacement only for another AirTAC SC tie-rod cylinder with a 40 mm bore, 970 mm stroke, PT ports, basic mount, and a magnet.
