The AirTAC Airtac SC40 Standard Cylinder SC40X150 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 AirTAC SC40X150 is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa and up to 1130 N at the maximum operating pressure of 0.9 MPa. Its 40 mm bore and 150 mm stroke suit medium-force clamping, pressing, and transfer tasks where a compact footprint is required.
This model features a 16 mm diameter piston rod with M12x1.25 male threads and PT1/4 pneumatic ports. The adjustable air cushion (21 mm length) decelerates the piston smoothly at end-of-stroke, reducing impact noise. The body length A is 142 mm, giving a total extended length of approximately 292 mm.

Moves small components between conveyor lanes or indexing stations with 628 N of push force at standard line pressure.
Provides controlled insertion force up to 1130 N for bearing or bushing press-fit operations in automated assembly cells.
Secures workpieces during machining or welding with a compact 40 mm bore cylinder that fits into tight fixture spaces.
Choose the SC40X150 for applications needing up to 628 N at standard shop air. If your load requires more force, step up to the SC50 series which provides 982 N at 0.5 MPa. For strokes of 300 mm or longer on this 40 mm bore, consider an external guide or a guided cylinder to protect the 16 mm rod from side-load bending.
When replacing an existing cylinder, match five points: 40 mm bore, 150 mm stroke, PT1/4 port thread, basic (no mounting accessory), and confirm whether a magnet (-S) is needed for sensors.
Quick checklist
At 0.5 MPa the push force is 628 N and the pull force is 528 N. At 0.7 MPa push rises to 879 N, and at the 0.9 MPa maximum operating pressure it reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The SC series is a tie-rod cylinder that is shorter than an ISO 15552 cylinder, so dimensional interchangeability is not guaranteed. It directly replaces another AirTAC SC40 cylinder with the same stroke, port thread, and mounting configuration.
