The AirTAC Airtac SC40 Standard Cylinder SC40X150STC is a genuine double-acting standard air cylinder with a Ø40mm bore and 150mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X150STC is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa and up to 1130 N at 0.9 MPa operating pressure. Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for the 150 mm stroke, making it a solid mid-range actuator for general automation.
This model includes a built-in magnet (-S) for mounting CMSG/DMSG/EMSG sensors directly on the tie-rod barrel, and ships with the TC centre trunnion mount and TCM1 bracket (F-SC40TC) for pivoting applications. The body length A is 142 mm, giving a compact footprint for space-constrained designs.

The 150 mm stroke and centre trunnion mount allow the cylinder to pivot smoothly, making it ideal for actuating diverter gates on conveyor lines handling small to medium packages.
With 1130 N of clamping force at 0.9 MPa and sensor-confirmed position feedback via the built-in magnet, this cylinder suits automated welding or assembly fixtures requiring precise end-of-stroke detection.
The TC trunnion mount absorbs side loads in pivoting linkages, and the 16 mm rod handles the 150 mm stroke without bending, suitable for press-lever or toggle mechanisms.
Choose the SC40 bore for push forces around 628 N at 0.5 MPa. If your load requires more force, step up to the SC50 bore (982 N at 0.5 MPa); for a lighter, more compact solution, the SC32 bore provides 402 N. This 150 mm stroke is well within the 1200 mm maximum standard stroke for the 40 mm bore.
For a drop-in replacement, match five key points: 40 mm bore, 150 mm stroke, PT port thread, TC centre trunnion mounting, and the built-in magnet (-S) for sensor compatibility. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC series cylinders.
Quick checklist
At the standard 0.5 MPa operating pressure, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 cylinder, so the mounting dimensions are not interchangeable. You must replace it with another AirTAC SC tie-rod cylinder of the same bore, stroke, port thread, and mounting type.
