The AirTAC SDA16X15S Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 15mm 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 SDA16X15S is a double-acting single-rod compact cylinder engineered for tight spaces. It produces 100.5 N of push force and 86.4 N of pull force at 0.5 MPa. The short riveted body significantly reduces axial mounting depth compared to round-body alternatives, making it ideal for dense machinery layouts.
This unit includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. End-of-stroke deceleration is handled by a fixed NBR bumper, not an adjustable cushion, so external shock absorbers are recommended for high-energy cycles. The hard-anodized 16 mm bore pairs with a 6 mm rod and M5x0.8 port.

Positions a small routing spindle across dense electronic panels where the 15 mm stroke and minimal axial footprint prevent frame collisions.
Actuates a lightweight deflector flap to sort small plastic bottles on a packaging line, utilizing the 100.5 N push force at 0.5 MPa.
Toggles a precision fluid nozzle for reagent dosing, relying on the integrated magnet to trigger an electronic switch for exact volume metering.
For sizing context, stepping down to the SDA12 yields 56.5 N of push at 0.5 MPa, while stepping up to the SDA20 provides 157.1 N. Note that a plain cylinder drifts when air is lost or a valve is centered; the fixed bumper only decelerates near stroke end rather than locking the load, so apply an external rod lock or pilot-operated check valve if position holding is required. Confirm ordering essentials: 16 mm bore, 15 mm stroke, M5x0.8 port, female M3x0.5 rod thread, and the -S magnet.
Quick checklist
At 0.5 MPa it provides 100.5 N push and 86.4 N pull. At 0.7 MPa it provides 140.7 N push and 121 N pull. The theoretical maximum push is 21 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. If you need to hold a load without live air pressure, the piston will drift, so you must add an external rod lock or pilot-operated check valve.
