The AirTAC Airtac SC40 Standard Cylinder SC40X185S is a genuine double-acting standard air cylinder with a Ø40mm bore and 185mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X185S is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa) from its 40 mm bore. With a 185 mm stroke and a 16 mm diameter piston rod, it suits medium-stroke clamping, pressing, and sorting tasks where consistent linear motion is required.
This model includes a built-in -S magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel for rod-position feedback. The body length A is 142 mm, giving a total extended length of approximately 327 mm. It uses PT1/4 ports and operates with filtered air from -20 to +70 °C with standard TPU seals.

The 185 mm stroke and 16 mm rod push packages or components onto a side chute, with the -S magnet confirming full extension and retraction for reliable sorting.
Delivers 628 N at 0.5 MPa for pressing bushings or bearings into housings, with sensor feedback ensuring consistent insertion depth on every cycle.
Operates a folding plate in case-packing machinery. The adjustable air cushion decelerates the 16 mm rod smoothly at end-of-stroke to protect the carton surface.
For applications needing more force, stepping up to the 50 mm bore provides 982 N at 0.5 MPa. If a shorter overall length is critical, the 32 mm bore (402 N at 0.5 MPa) may be sufficient. This cylinder is a genuine AirTAC SC tie-rod type, so direct replacement requires matching the 40 mm bore, 185 mm stroke, PT1/4 port thread, and the -S magnet option for sensor compatibility. Always confirm the mounting accessory; this basic body needs separate order of an F-SC40 mount (LB, FA, FB, CA, CB, or TC) if a bracket is required.
Quick checklist
At 0.5 MPa it produces 628 N pushing and 528 N pulling. At the maximum operating pressure of 0.9 MPa, the push force rises to 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes. The -S suffix means a magnet is built into the piston, so AirTAC CMSG, DMSG, or EMSG sensors can be clamped onto the tie-rods to detect rod position without additional brackets.
