The AirTAC Airtac SC40 Standard Cylinder SC40X215 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 SC40X215 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a push force of 628 N at 0.5 MPa and up to 1130 N at 0.9 MPa. Its 40 mm bore and 215 mm stroke suit medium-duty linear tasks where a compact envelope is needed, with a 16 mm diameter piston rod providing good column strength for pushing applications.
Built with an adjustable air cushion (21 mm cushion length) at both ends, this cylinder decelerates the piston smoothly to reduce end-of-stroke impact. The body length A is 142 mm, giving a total extended length of approximately 357 mm. TPU seals handle a standard temperature range of -20 to +70 °C, and the PT1/4 ports connect easily to common pneumatic fittings.

Actuates a diverter flap on a packaging conveyor, using 628 N push force to redirect cartons reliably at 0.5 MPa line pressure.
Powers a pneumatic clamp in a machining centre, holding workpieces with up to 1130 N of force at 0.9 MPa for stable cutting operations.
Drives a small tilt mechanism on a parts bin, using the 215 mm stroke to achieve the required dump angle in a compact footprint.
Choose the SC40X215 when your application needs around 628 N of force at standard shop air. If you require more thrust, stepping up to the SC50 bore delivers 982 N push at the same 0.5 MPa. For strokes above 300 mm on a 40 mm bore, be cautious of side loading—the 16 mm rod can bend under off-axis forces, so consider an external guide or a guided cylinder. When replacing an existing unit, match five points: 40 mm bore, 215 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and no magnet.
Quick checklist
At 0.5 MPa, push force is 628 N and pull force is 528 N. At 0.7 MPa, push reaches 879 N. The maximum push force at 0.9 MPa operating pressure is 1130 N.
No, the SC40X215 is a double-acting cylinder and will not hold position if pressure is lost or the directional valve is centred. The adjustable air cushion only decelerates the piston at stroke end—it is not a locking device. For load holding without live pressure, add a pilot-operated check valve or an external rod brake.
