The AirTAC Airtac SC40 Standard Cylinder SC40X100SCB is a genuine double-acting standard air cylinder with a Ø40mm bore and 100mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X100SCB is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering 628 N of push force at 0.5 MPa and up to 1130 N at the 0.9 MPa maximum operating pressure. Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for a 100 mm stroke, making it a compact workhorse for medium-duty linear tasks.
This configuration includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, plus a rear double clevis bracket (CB mount, accessory F-SC40CB) that allows the cylinder body to pivot. The default TPU seals and PT1/4 port threads keep it compatible with standard filtered-air systems from -20 to +70 °C.

The 100 mm stroke and rear clevis pivot suit diverting flaps or gates on packaging conveyors, where the cylinder body needs to swing as it extends and retracts.
With 628 N of clamping force at standard line pressure and magnetic sensor feedback, it confirms part presence and clamp status in machining or welding fixtures.
The TPU seals handle dusty, damp environments, and the rear clevis mount fits linkage-actuated chutes or diverter plates on seeders and harvesters.
Choose the SC40X100SCB when your application needs roughly 600-1100 N of force and a pivoting rear mount. If you require more thrust, step up to the SC50 bore (982 N push at 0.5 MPa); for a lighter, more compact solution, the SC32 bore offers 402 N. The built-in magnet lets you add position sensors without extra brackets, simplifying stroke-end confirmation.
For replacement, match five points: 40 mm bore, 100 mm stroke, PT1/4 port thread, rear double clevis (CB) mounting accessory F-SC40CB, and the -S magnet option. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders; always verify body length A (142 mm) and clevis pin dimensions against your existing setup.
Quick checklist
At 0.5 MPa the cylinder delivers 628 N pushing and 528 N pulling. At the maximum operating pressure of 0.9 MPa, push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length (142 mm body plus stroke) than a typical ISO 15552 cylinder of the same bore. It is not dimensionally interchangeable. Only replace another AirTAC SC tie-rod cylinder with matching bore, stroke, port thread, CB mount, and magnet option.
