The AirTAC Airtac SC40 Standard Cylinder SC40X23S is a genuine double-acting standard air cylinder with a Ø40mm bore and 23mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X23S is a double-acting AirTAC SC series tie-rod cylinder with a 40 mm bore and a non-standard 23 mm stroke, built for compact linear push-pull tasks. Its 16 mm diameter piston rod delivers 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa), giving it a solid force reserve for a small-bore cylinder.
This model includes the -S suffix, so a magnet is built into the piston. That lets you clamp CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the barrel for reliable, non-contact end-of-stroke or mid-stroke position sensing. The body length A is 142 mm, keeping the overall envelope short.

The built-in magnet allows direct mounting of CMSG/DMSG sensors to confirm clamp closure on small assembly fixtures, preventing cycle start without part presence.
With 628 N of push force, the SC40X23S is ideal for a compact pneumatic part stop on a conveyor lane, singulating small packages with a 23 mm stroke.
The short, non-standard 23 mm stroke and magnetic piston sensing make this cylinder a good fit for actuating an ejector mechanism in a small injection mold tool.
Choose the SC40 when your application needs more force than the 32 mm bore (402 N push at 0.5 MPa) but the 50 mm bore (982 N) would be oversized. For this 23 mm stroke, confirm the short cushion length of 21 mm still provides adequate deceleration for your load speed.
When replacing an existing cylinder, match five points: 40 mm bore, 23 mm stroke, PT1/4 port thread, the built-in magnet (-S), and your mounting accessory. The SC is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.7 MPa operating pressure, the 40 mm bore SC cylinder produces 879 N of push force. The pull force on the retract stroke is 528 N at 0.5 MPa, accounting for the 16 mm rod area.
Yes. The -S suffix in SC40X23S means a magnet is built into the piston. You can mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly on the cylinder barrel's sensor groove to detect piston position.
