The AirTAC Airtac SC40 Standard Cylinder SC40X105S is a genuine double-acting standard air cylinder with a Ø40mm bore and 105mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X105S is a double-acting AirTAC tie-rod cylinder with a 40 mm bore and 105 mm stroke, pre-fitted with a magnet for direct mounting of CMSG, DMSG, or EMSG sensors. It produces 628 N of push force and 528 N of pull force at 0.5 MPa, making it a reliable actuator for mid-range positioning and clamping tasks.
With a 16 mm diameter piston rod and M12x1.25 rod-end thread, this cylinder handles moderate side loads better than smaller bores. The 21 mm adjustable air cushion at each end decelerates the piston smoothly, and the compact body length of 142 mm plus stroke keeps the overall envelope tight for machine builders.

The 105 mm stroke and 628 N push force at 0.5 MPa suit conveyor line part stops and diverter gates where sensor-confirmed position is needed for cycle start.
Delivers consistent clamping force for CNC jigs and welding fixtures. The built-in magnet enables compact sensor mounting to verify clamp/unclamp status in automated cells.
Ideal for label applicators and hot-stamp presses requiring a clean 105 mm linear stroke with adjustable cushioning to prevent impact damage at cycle rates up to 800 mm/s.
Choose the SC40 bore when the SC32's 402 N push at 0.5 MPa is marginal. If your application demands more than 879 N at 0.7 MPa, step up to the SC50 (1374 N at 0.7 MPa). The built-in magnet (suffix -S) allows CMSG/DMSG/EMSG solid-state or reed sensors to clamp directly onto the barrel for end-of-stroke or mid-stroke position feedback without external brackets.
For a direct replacement, match these five points: 40 mm bore, 105 mm stroke, PT1/4 port thread, the built-in magnet (-S), and the basic (no bracket) mounting. This is a tie-rod cylinder, not an ISO 15552 profile unit, so dimensional interchangeability is limited to other AirTAC SC40 tie-rod cylinders.
Quick checklist
At the standard operating pressure of 0.5 MPa, this cylinder generates 628 N pushing force and 528 N pulling force. At the maximum operating pressure of 0.9 MPa, it produces 1130 N pushing force. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes. The -S suffix indicates a built-in magnet, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clamp directly onto the barrel without additional brackets or modifications.
