The AirTAC Airtac SC40 Standard Cylinder SC40X175SCA 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 SC40X175SCA is a 40 mm bore double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 175 mm stroke suits medium-reach clamping and transfer tasks, with a 16 mm diameter piston rod providing robust linear guidance.
This configuration includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors and a rear single clevis (CA suffix, part F-SC40CA) for pivoting attachment. The cylinder body length A is 142 mm, and the adjustable air cushion at each end decelerates the piston smoothly over 21 mm.

Moves components between stations on a linear transfer line, using the clevis mount to accommodate slight angular misalignment during the push stroke.
Applies 628 N of holding force at 0.5 MPa in a pivoting welding or assembly jig, with sensor confirmation of the clamped position via the built-in magnet.
Opens and closes a small hopper gate or diverter chute, where the rear clevis allows the cylinder body to swing as the gate arcs through its travel.
For higher force, step up to the 50 mm bore (982 N at 0.5 MPa); for a lighter, more compact unit, the 32 mm bore offers 402 N. The 175 mm stroke is within the 1200 mm maximum standard stroke for this bore. When replacing, match bore, stroke, PT port thread, the -S magnet option, and the CA rear clevis mounting to ensure dimensional and functional interchangeability.
Quick checklist
At the standard operating pressure of 0.5 MPa, the cylinder pushes with 628 N and pulls with 528 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length (A=142 mm) than an equivalent ISO 15552 profile cylinder. It is a direct dimensional match only for another AirTAC SC40 tie-rod cylinder with the same stroke, PT ports, magnet option, and CA rear clevis mount.
