The AirTAC Airtac SC40 Standard Cylinder SC40X58S is a genuine double-acting standard air cylinder with a Ø40mm bore and 58mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X58S is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa, making it a solid mid-range actuator for general automation. Its 40 mm bore houses a 16 mm diameter piston rod with M12x1.25 male threads, and the 58 mm stroke fits compact linear-transfer and clamping stations where space is tight.
This model includes the factory-installed -S magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for end-of-stroke detection. The body length A is 142 mm, giving a total extended length of approximately 200 mm, and the adjustable air cushion at each end is 21 mm long to soften piston impact.

The built-in magnet enables CMSG/DMSG sensors to confirm retract or extend position, ideal for conveyor gates and part-stops where PLC feedback is required.
With 628 N of push force and a 58 mm stroke, this cylinder suits light-duty clamping and holding of small workpieces in CNC or assembly jigs.
The 40 mm bore provides enough force to divert small cartons or totes on roller conveyors, and the magnetic piston confirms each cycle.
Choose the SC40 bore when your application needs between 528 N (pull) and 628 N (push) at 0.5 MPa. If your load exceeds 800 N, step up to the SC50 bore (982 N push at 0.5 MPa); for lighter loads under 400 N, the SC32 bore (402 N push) may reduce air consumption. For a drop-in replacement, match bore (40 mm), stroke (58 mm), port thread (PT1/4), mounting style, and the -S magnet option—the SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At the standard operating pressure of 0.5 MPa, the cylinder produces 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 -S suffix indicates a magnetized piston ring. It is designed for AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors that clamp onto the barrel's tie-rod grooves. Always confirm sensor compatibility with your controller input type.
