The AirTAC Airtac SC40 Standard Cylinder SC40X175SN is a genuine double-acting standard air cylinder with a Ø40mm bore and 175mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X175SN is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore and 175 mm stroke suit medium-force clamping, pressing, and material-transfer tasks where a compact footprint matters.
This model carries a built-in magnet (-S suffix) so CMSG/DMSG/EMSG reed or solid-state sensors clamp directly onto the barrel for non-contact position sensing. The -N suffix specifies NBR (nitrile) seals, making it a good match for general industrial air service. The 16 mm diameter rod resists bending, and the 21 mm adjustable air cushion at each end decelerates the piston smoothly.

Pushes or diverts packages and components on conveyors. The 175 mm stroke gives enough reach for lane diverters, and the built-in magnet lets sensors confirm end-of-stroke every cycle.
Applies 628 N at 0.5 MPa for pressing bushings, bearings, or clips into housings. NBR seals handle standard shop air, and the adjustable cushion protects the assembly from impact shock.
Clamps workpieces during machining or bonding. The -S magnet allows two magnetic sensors to verify both clamped and retracted positions, preventing cycle-start errors on automated fixtures.
Choose the SC40X175SN when 628 N at 0.5 MPa covers the load with a safe margin. If the load approaches 800-900 N, step up to the SC50 bore (982 N push at 0.5 MPa) to keep speed stable. For a lighter load under 350 N, the SC32 bore (402 N push) may reduce air consumption.
To replace an existing cylinder, match five points: 40 mm bore, 175 mm stroke, PT1/4 port thread, the built-in magnet for sensors, and the basic (no bracket) mounting. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.7 MPa the SC40 bore generates 879 N of push force. The pull force on the rod side is lower because of the 16 mm rod area; at 0.5 MPa pull force is 528 N.
Yes. The -S suffix means a magnet is built into the piston, so AirTAC CMSG, DMSG, or EMSG sensors clip onto the barrel's sensor groove. Without the -S option, magnetic sensors will not switch.
