The AirTAC Airtac SC40 Standard Cylinder SC40X100SFA 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 SC40X100SFA is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 100 mm stroke and 16 mm diameter piston rod suit clamping, pressing, and ejector tasks where a compact tie-rod body is preferred.
This configuration includes a built-in magnet (suffix S) for mounting CMSG/DMSG/EMSG sensors directly on the barrel, plus an FA front rectangular flange (F-SC40FA) for rigid panel mounting at the rod end. Seals are standard TPU, rated for -20 to +70 °C, with PT threaded ports.

The 628 N force at 0.5 MPa and compact 100 mm stroke make this cylinder ideal for pneumatic fixture clamps on CNC machining centres, where the magnet confirms clamp position before a cycle start.
Front-flange mounting allows the cylinder to be bolted directly to a conveyor side rail. The 100 mm stroke pushes rejected parts off the belt, with the magnetic piston signalling end-of-stroke to the PLC.
Delivers up to 1130 N at 0.9 MPa for pressing bushings or connectors. The front flange provides a rigid, aligned mount on the press frame, while the built-in magnet enables sensor-based quality interlocking.
For higher force, step up to the SC50 bore (982 N push at 0.5 MPa). For lower force in the same mounting style, the SC32 bore provides 402 N. The 100 mm stroke is well within the 1200 mm maximum standard stroke for bore 40, so this is a stock-configuration cylinder.
When replacing, match five points: 40 mm bore, 100 mm stroke, PT port thread, FA front flange mount, and the -S magnet for sensor compatibility. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At the standard 0.5 MPa operating pressure, the cylinder produces 628 N extending (push) and 528 N retracting (pull). At the maximum operating pressure of 0.9 MPa, push force increases to 1130 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder. It is not dimensionally interchangeable. Use it to replace another AirTAC SC40 tie-rod cylinder with matching bore, stroke, PT ports, FA front flange, and magnet option.
