The AirTAC Airtac SC40 Standard Cylinder SC40X402S is a genuine double-acting standard air cylinder with a Ø40mm bore and 402mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X402S is a double-acting single-rod pneumatic cylinder with a 40 mm bore and a 402 mm stroke, delivering a push force of 628 N at 0.5 MPa (up to 1130 N at 0.9 MPa). The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors on the tie-rod barrel for reliable end-of-stroke detection without external brackets.
This model uses a 16 mm diameter piston rod with an M12x1.25 knuckle thread and PT1/4 ports. The adjustable air cushion at each end (21 mm length) decelerates the piston smoothly, reducing impact noise and wear. The body length A is 142 mm, giving a total extended length of approximately 544 mm.

Operates diverter gates on packaging conveyors where mid-stroke sensor confirmation via the built-in magnet ensures precise product sorting at 402 mm of travel.
Provides 628 N of clamping force for assembly jigs; the magnetic piston allows fitment of solid-state sensors to verify clamp engagement before a cycle starts.
Positions test samples or reagent trays in automated lab workcells, using the 402 mm stroke for deep access and magnetic sensors for multi-position feedback.
For applications needing slightly less force, the 32 mm bore SC32 series provides 402 N push at 0.5 MPa. If higher force is required, step up to the 50 mm bore SC50 series, which delivers 982 N at the same pressure. Always match replacement cylinders on five points: bore, stroke, port thread (PT), mounting accessory, and magnet option (this model includes the -S magnet).
At this 402 mm stroke, the 16 mm rod is subject to bending moments if side loads are present. For long-stroke applications, use an external guide or switch to a guided cylinder to protect the rod bearing and ensure consistent cycling life.
Quick checklist
At 0.5 MPa the cylinder pushes with 628 N and pulls with 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.
Yes. The -S suffix indicates a built-in magnet in the piston, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clip directly onto the tie-rod barrel without extra mounting hardware.
