The AirTAC Airtac SC40 Standard Cylinder SC40X150SN 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 SC40X150SN is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore and 150 mm stroke suit medium-force linear tasks, with a 16 mm diameter piston rod providing robust guidance for the load.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors on the barrel, enabling simple end-of-stroke detection. The NBR seals (-N suffix) offer reliable sealing for standard industrial air, and PT1/4 ports connect to common pneumatic circuits. The adjustable air cushion at each end decelerates the piston smoothly over a 21 mm cushion length.

Moves components between conveyor lanes or assembly stations with consistent 150 mm travel. The built-in magnet allows sensors to confirm extend and retract positions for reliable automation sequencing.
Applies up to 1130 N of clamping force at 0.9 MPa for workpiece fixturing. NBR seals and double-acting control ensure stable pressure throughout the machining or welding cycle.
Operates diverter gates on packaging or logistics lines. The 16 mm rod and tie-rod construction handle the repetitive cycling, while magnetic sensors provide gate-position feedback to the PLC.
Choose the SC40 bore for applications needing up to 628 N at 0.5 MPa. If your force requirement is lower, the SC32 bore provides 402 N at the same pressure in a more compact body. For higher force, step up to the SC50 which delivers 982 N at 0.5 MPa.
To ensure a correct replacement, match five key points: bore (40 mm), stroke (150 mm), PT port thread, the built-in magnet (-S) for sensor compatibility, and the basic mounting style. For this 150 mm stroke, the standard tie-rod construction provides adequate support, but always align the load axially to prevent side-loading the rod bearing.
Quick checklist
At the standard operating pressure of 0.5 MPa, 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.
Yes, if the original unit is an AirTAC SC tie-rod cylinder with a 40 mm bore, 150 mm stroke, PT ports, basic mount, and a built-in magnet. The SC series is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders. Always verify port size and sensor compatibility before ordering.
