The AirTAC Airtac SC40 Standard Cylinder SC40X170S is a genuine double-acting standard air cylinder with a Ø40mm bore and 170mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X170S is a double-acting single-rod pneumatic cylinder from the AirTAC SC tie-rod series. With a 40 mm bore and 170 mm stroke, it produces a push force of 628 N at 0.5 MPa and up to 1130 N at the maximum operating pressure of 0.9 MPa, making it a capable mid-range actuator for general automation.
This model includes the -S suffix, meaning a built-in magnet is fitted as standard. This allows easy, tool-free mounting of CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the barrel for precise end-of-stroke or mid-stroke position sensing. The 16 mm diameter piston rod and 21 mm adjustable air cushion ensure smooth deceleration, while the PT1/4 port provides standard connectivity.

The 170 mm stroke and 628 N push force at 0.5 MPa efficiently actuates diverter gates on medium-speed package handling conveyors. The built-in magnet provides clean sensor feedback for gate open/closed confirmation.
Delivers consistent, controlled clamping force for CNC woodworking or light metal fabrication jigs. The adjustable cushion protects the workpiece from impact damage at the end of the stroke.
Positions a filling nozzle or actuates a scraper bar across a 170 mm travel in automated nursery lines. The magnetic piston allows easy integration of cycle-counting sensors for precise batch control.
Select the SC40 bore when your application needs between 528 N (pull) and 628 N (push) of force at standard 0.5 MPa shop air. If your load requires more force, stepping up to the SC50 bore provides 982 N of push force at the same pressure. For lighter, more compact needs, the SC32 bore delivers 402 N.
For this 170 mm stroke, the rod bearing is well-supported, but always ensure the load is guided and aligned axially to prevent side-loading. For a drop-in replacement, match these five points: 40 mm bore, 170 mm stroke, PT1/4 port thread, the built-in magnet (-S), and the basic (footless) mounting configuration.
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 increases to 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
Yes. The -S suffix in SC40X170S indicates a built-in magnetic piston. This allows you to mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder barrel's tie-rod slots to detect piston position without any additional brackets.
