The AirTAC Airtac SC40 Standard Cylinder SC40X100STC 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 SC40X100STC is a 40 mm bore double-acting tie-rod cylinder with a 100 mm stroke, factory-configured with a built-in magnet and centre trunnion mount. At 0.5 MPa it provides 628 N of push force and 528 N of pull force, making it a capable mid-range actuator for pivoting applications.
This model uses a 16 mm diameter piston rod with an M12x1.25 knuckle thread and PT1/4 ports. The adjustable cushion is 21 mm long, and the body length A is 142 mm. The -S magnet allows direct mounting of CMSG/DMSG/EMSG sensors on the barrel for reliable end-of-stroke detection.

The trunnion mount allows the cylinder to swing a diverter gate on a conveyor line, directing packages or components to different lanes based on sensor input.
Provides 628 N of clamping force for holding parts in a welding jig. The magnet confirms the clamp is fully closed before the welding cycle starts.
Controls a discharge chute on a small agricultural hopper. The pivoting action manages material flow, and the sensor confirms the open/closed position.
The centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC40TC), allows the cylinder to pivot during operation, ideal for swinging loads. When selecting, ensure the trunnion position suits your pivot point. If your force requirement is close to the limit, stepping up to the 50 mm bore (982 N push at 0.5 MPa) provides a significant margin. For a drop-in replacement, match the 40 mm bore, 100 mm stroke, PT1/4 ports, TC mount, and the -S magnet option.
Quick checklist
At the standard operating pressure of 0.5 MPa, this cylinder produces 628 N pushing out and 528 N pulling in. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N.
Yes, if the old unit is an AirTAC SC tie-rod cylinder or a compatible equivalent matching these five points: 40 mm bore, 100 mm stroke, PT1/4 ports, centre trunnion (TC) mounting, and a built-in magnet for sensors. The TC mount includes the TCM1 bracket.
