The AirTAC SDA16X65 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 SDA16X65 is a double-acting, single-rod compact cylinder engineered for tight axial spaces. It generates 100.5 N of push force and 86.4 N of pull force at 0.5 MPa. Because the 65 mm stroke exceeds the 60 mm standard limit for this 16 mm bore, this unit is provided as a non-standard, made-to-order configuration.
A riveted assembly joins the barrel, rear cover, and piston to minimize overall length, making it ideal for shrinking a machine footprint. The bore is hard-anodized for longevity, while a fixed NBR bumper at each end absorbs end-stop impact. This SKU lacks a piston magnet, so it cannot support position sensing without upgrading to the -S option.

Pushes printed circuit boards out of an SMT line testing fixture using a short 65 mm extension, fitting neatly within the dense routing of the electronics conveyor.
Actuates a diverter flap in a vibratory bowl feeder to route 16 mm hardware components, applying 100.5 N of thrust to ensure positive mechanical displacement.
Tucks the minor side flaps of a small pharmaceutical carton prior to sealing, utilizing the compact riveted body to fit inside narrow packaging machine frames.
When sizing this actuator, compare its output against adjacent bores: 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. To order, confirm the 16 mm bore, 65 mm non-standard stroke, M5x0.8 port, female M3x0.5 rod thread, and the absence of a magnet. Note that a plain SDA cylinder drifts if air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a locking brake. To suspend a load safely, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, the push force is 100.5 N and the pull force is 86.4 N. At 0.7 MPa, the push force is 140.7 N and the pull force is 121 N. The theoretical maximum push force is 21 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and the operating speed ranges from 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot trigger AirTAC reed or electronic switches. To add sensing capabilities, you must specify the -S option when ordering. Additionally, this model relies on a fixed NBR bumper at each end to decelerate the piston; it is not an adjustable air cushion, so external shock absorbers may be needed for high-speed operations.
