The AirTAC Airtac SC40 Standard Cylinder SC40X370S is a genuine double-acting standard air cylinder with a Ø40mm bore and 370mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X370S is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 370 mm stroke is well within the 1200 mm maximum standard stroke for the 40 mm bore, making this a standard-configuration actuator ready for immediate shipment.
A built-in magnet (denoted by the -S suffix) allows CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for reliable end-of-stroke or mid-stroke position feedback. The 16 mm diameter piston rod and adjustable air cushion at each end help manage deceleration in medium-speed automation tasks.

The 370 mm stroke and 628 N push force at 0.5 MPa reliably shift package diverters on medium-width conveyors, with the built-in magnet confirming gate position via barrel-mounted sensors.
Delivers consistent clamping pressure for CNC or welding fixtures. The adjustable cushion protects the workpiece and tooling from impact shock at the end of the 370 mm travel.
Ideal for stopping or lifting pallets at transfer stations. The sensor-ready barrel enables integration with automated warehouse control systems for precise end-of-stroke detection.
For applications needing more force, stepping up to the SC50 series provides 982 N at 0.5 MPa. If a shorter stroke and lower flow consumption are acceptable, the SC40X300 reduces the extended length. The 370 mm stroke on a 16 mm rod is suitable for many push/pull operations, but users should verify that side loads are minimal; for guided or cantilevered loads, an external guide rail or a guided cylinder is recommended to protect the rod bearing from bending moments.
When replacing an existing cylinder, match five points: 40 mm bore, 370 mm stroke, PT1/4 port thread, the basic (no-bracket) mounting configuration, and the presence of a magnet for sensor compatibility. This SC40X370S is a genuine AirTAC tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa operating pressure, the cylinder provides 628 N extending (push) and 528 N retracting (pull). At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes. The -S suffix indicates a built-in magnet on the piston. You can clamp compatible AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rod slots without any additional brackets.
