The AirTAC Airtac SC40 Standard Cylinder SC40X215S is a genuine double-acting standard air cylinder with a Ø40mm bore and 215mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X215S is a double-acting pneumatic cylinder with a 40 mm bore and a non-standard 215 mm stroke, factory-built with a built-in magnet for sensor mounting. At 0.5 MPa it provides 628 N of push force, making it suitable for medium-duty clamping and transfer tasks.
This model uses a 16 mm diameter piston rod with an M12x1.25 male thread and PT1/4 ports. The adjustable air cushion (21 mm length) decelerates the piston smoothly, and the total extended body length is approximately 357 mm. The integrated magnet allows CMSG/DMSG/EMSG sensors to be clamped directly onto the tie-rod barrel for reliable end-of-stroke detection.

The 628 N push force at 0.5 MPa is ideal for stopping or diverting medium-weight packages on belt conveyors, with magnetic sensors confirming gate position.
Delivers consistent clamping pressure for CNC jigs and welding fixtures. The 215 mm stroke provides ample clearance for part loading and unloading.
Used in benchtop assembly stations for pressing bushings or bearings, where the adjustable cushion prevents impact damage to delicate components.
For applications needing more force, stepping up to the 50 mm bore SC50 series provides 982 N at 0.5 MPa. If the 215 mm stroke is close to the maximum, verify that the rod is adequately supported against side loads; long unsupported strokes can cause rod bearing wear and bending. An external guide or a guided cylinder is recommended when the rod must handle lateral forces.
To replace this cylinder, match five points: 40 mm bore, 215 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and the basic mounting style. This tie-rod SC design is shorter than an ISO 15552 cylinder and is not dimensionally interchangeable with that standard.
Quick checklist
At 0.5 MPa the cylinder pushes with 628 N and pulls with 528 N. 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, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors can be clamped directly onto the tie-rod barrel without additional brackets.
