The AirTAC Airtac SC40 Standard Cylinder SC40X16 is a genuine double-acting standard air cylinder with a Ø40mm bore and 16mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X16 is a compact-stroke variant of the AirTAC SC tie-rod cylinder, pairing a 40 mm bore with a short 16 mm stroke. At 0.5 MPa it generates 628 N pushing force, making it suitable for clamping, ejecting, or short-transfer tasks where space is tight.
This double-acting cylinder uses a 16 mm diameter piston rod with M12x1.25 male threads and PT1/4 ports. The body length A is 142 mm, and the adjustable air cushion at each end (21 mm cushion length) helps reduce end-of-stroke impact even in rapid short-stroke cycling.

Delivers 628 N at 0.5 MPa in a 16 mm stroke, ideal for compact fixture clamps and workpiece holding in CNC or assembly jigs.
Rapid short-travel ejection of small parts from dies or moulds, where the 40 mm bore provides enough force to overcome sticking.
Operates small diverter gates or stops on conveyor lines, using the short stroke for fast cycle times in sorting applications.
Choose the SC40X16 when you need a 40 mm bore force class in a very short stroke—note that 16 mm is below the standard range and is a non-standard made-to-order stroke. If your load requires more force, step up to the SC50 bore (982 N push at 0.5 MPa); for a lighter, more compact solution, the SC32 offers 402 N.
For replacement, match five points: bore (40 mm), stroke (16 mm), PT1/4 port thread, the required mounting accessory (this is a basic body, so order LB/FA/FB/CA/CB/TC brackets separately if needed), and confirm whether a magnet (-S) is required for sensor mounting.
Quick checklist
At 0.7 MPa supply pressure the SC40X16 delivers 879 N of pushing force (theoretical). At the maximum operating pressure of 0.9 MPa it reaches 1130 N push.
No—the 16 mm stroke is below the standard stroke range for the SC40 bore. Standard strokes start at 25 mm. A 16 mm stroke is a non-standard made-to-order item; check lead time with your AirTAC distributor.
