The AirTAC AirTAC SDA16X65S Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 65mm stroke, M5×0.8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA16X65S is a double-acting single-rod compact cylinder delivering 100.5 N of push force at 0.5 MPa. Its riveted assembly significantly reduces axial mounting depth, making it ideal for machinery where a standard round body would be too long. The 6 mm piston rod utilizes a female M3x0.5 thread, and the bore features a hard-anodized surface for extended operational life.
This specific 65 mm unit is a non-standard made-to-order stroke, exceeding the 60 mm maximum standard length for this 16 mm bore. It includes a built-in piston magnet (-S) for position sensing via AirTAC reed or electronic switches fitted into the body grooves. End stops rely on a fixed NBR bumper rather than an adjustable air cushion, which safely decelerates the piston near stroke completion.

Actuates the cutting head feed on a printed circuit board routing machine, utilizing the 100.5 N push force and 65 mm travel to separate panels without excessive axial bulk.
Drives the upper heat platen in a small blister packaging press, where the short riveted body conserves vertical space and the built-in magnet confirms seal position.
Toggles a precision fluid dispensing nozzle in automated laboratory equipment, relying on the 6 mm rod and female M3x0.5 thread for accurate tooling coupling.
When sizing this 16 mm bore, consider stepping down to the SDA12 which provides 56.5 N push at 0.5 MPa, or moving up to the SDA20 which yields 157.1 N push at 0.5 MPa. Based on the 100.5 N output, the safe working load is approximately 60 N, translating to a vertical lift capacity of about 5.1 kg with a 2:1 safety margin.
Keep in mind that a basic compact cylinder cannot hold a load if air pressure drops or the valve is centered; the piston will drift, as the fixed bumper only slows travel at the very end. For secure load holding, integrate an external rod lock or a pilot-operated check valve. To order, confirm the 16 mm bore, 65 mm non-standard stroke, M5x0.8 port, built-in magnet (S), and female rod thread.
Quick checklist
This double-acting 16 mm bore cylinder generates 100.5 N push and 86.4 N pull at 0.5 MPa. At 0.7 MPa, it provides 140.7 N push and 121 N pull. The theoretical maximum push is 21 kgf at the 1.0 MPa operating pressure limit.
No, this model uses a fixed NBR bumper at each end to decelerate the piston, not an adjustable air cushion. If your application involves high kinetic energy, you should slow the approach speed or add an external shock absorber.
