The AirTAC Airtac SC40 Standard Cylinder SC40X50S is a genuine double-acting standard air cylinder with a Ø40mm bore and 50mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X50S is a double-acting pneumatic cylinder with a 40 mm bore and 50 mm stroke, equipped with a built-in magnet for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors. Its 16 mm diameter piston rod and PT1/4 port provide a compact yet robust actuation package for short-stroke applications.
At 0.5 MPa air pressure, this cylinder generates 628 N of pushing force and 528 N on the pull stroke, rising to 1130 N push at 0.9 MPa. The adjustable air cushion at each end decelerates the piston over 21 mm to reduce end-of-stroke impact, and the standard TPU seals suit operating temperatures from -20 to +70 °C.

The 50 mm stroke and sensor-ready magnet allow precise end-of-stroke detection for sorting packages on a belt conveyor, confirming gate position with every cycle.
Delivers 628 N of clamping force at 0.5 MPa. The built-in magnet lets a CMSG sensor verify the clamp is fully engaged before a machining cycle starts.
Compact 40 mm bore and clean double-acting motion suit repetitive reagent dispensing. Sensor feedback confirms each dispense stroke for traceability.
Choose the SC40X50S when your application needs sensor feedback in a compact 40 mm bore envelope. If you require higher force, stepping up to the 50 mm bore SC50 series provides 982 N push at 0.5 MPa, while the smaller 32 mm bore SC32 offers 402 N for lighter tasks. The 50 mm stroke is well within the 1200 mm maximum standard stroke for this bore.
For replacement, match five key points: 40 mm bore, 50 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and your required mounting accessory. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa, the cylinder provides 628 N pushing force and 528 N pulling force. At the maximum operating pressure of 0.9 MPa, the pushing force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes. The -S suffix indicates a built-in magnet, so AirTAC CMSG, DMSG, or EMSG sensors clamp directly onto the barrel to detect piston position without external brackets or flags.
