The AirTAC Airtac SC40 Standard Cylinder SC40X160 is a genuine double-acting standard air cylinder with a Ø40mm bore and 160mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X160 is a double-acting pneumatic cylinder delivering 628 N of push force and 528 N of pull force when operated at 0.5 MPa. With a 40 mm bore and 160 mm stroke, this model is built on a tie-rod construction that makes it shorter than an ISO 15552 cylinder, saving space in machine frames.
It features a 16 mm diameter piston rod with an M12x1.25 thread and an adjustable air cushion (21 mm length) to decelerate the piston smoothly at end of travel. The body length A is 142 mm, giving a total extended length of approximately 302 mm. Standard PT1/4 ports and TPU seals rated for -20 to +70 °C are fitted.

Actuates a gate or diverter flap on a conveyor line, using the 160 mm stroke to push products onto a secondary lane with 628 N of force at standard line pressure.
Provides the insertion force for press-fitting bushings or bearings into housings. The adjustable cushion protects the tooling and part from impact damage.
Secures a workpiece in a CNC fixture or welding jig. The double-acting function ensures positive clamping and release, with the 16 mm rod resisting deflection.
This 40 mm bore cylinder suits mid-force clamping, pressing, and transfer tasks. If you need more force, stepping up to the 50 mm bore (982 N push at 0.5 MPa) provides a significant jump. For lighter, faster applications, the 32 mm bore (402 N push) may be a better fit.
When replacing an existing unit, match five points: bore (40 mm), stroke (160 mm), port thread (PT1/4), mounting accessory (basic, no bracket), and magnet option (none). For strokes of 300 mm or longer, consider an external guide or a guided cylinder to protect the rod from side-load bending, though at 160 mm this model is generally rigid enough for axial loads.
Quick checklist
At 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 reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 cylinder of the same bore and stroke. It is not dimensionally interchangeable with ISO 15552 profiles. It is a direct replacement for another AirTAC SC40 cylinder with matching stroke, port, and mount.
