The AirTAC Airtac SC40 Standard Cylinder SC40X220S is a genuine double-acting standard air cylinder with a Ø40mm bore and 220mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X220S is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range automation tasks.
This model includes a built-in magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly on the tie-rod barrel for contactless position sensing. The 220 mm stroke is well within the 1200 mm maximum standard stroke for the 40 mm bore.

The 628 N push force at 0.5 MPa is ideal for diverting cartons or products on a packaging line, with the magnetic piston enabling end-of-stroke verification.
Provides consistent clamping force for CNC fixtures or assembly jigs. The built-in magnet allows sensors to confirm the clamp is fully engaged before machining starts.
Suitable for small pneumatic presses in lab environments, offering clean operation and adjustable cushioning to protect delicate samples or tooling.
For higher force, the 50 mm bore SC50 series offers 982 N at 0.5 MPa. If space is tight, stepping down to the 32 mm bore provides 402 N. The 220 mm stroke on a 16 mm rod is stable for axial loads, but any significant side force requires an external linear guide to prevent rod bearing wear and bending. For direct replacement, match the bore, stroke, PT port thread, basic mount, and the -S magnet option.
Quick checklist
At the standard operating pressure of 0.5 MPa, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N.
Yes. The -S suffix indicates a built-in magnet in the piston. This allows AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors to be clamped onto the cylinder's tie-rod barrel to detect piston position.
