The AirTAC SDA16X65SB 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 SDA16X65SB is a double-acting single-rod compact cylinder engineered where axial depth is restricted. Its riveted assembly unites the barrel, rear cover, piston, and rod to shrink the overall footprint compared to round-body units.
This specific configuration includes a built-in piston magnet (-S) for tracking position via AirTAC reed or electronic switches, plus a male M5x0.8 threaded rod end (-B) instead of the default female M3x0.5. Because the 65 mm stroke exceeds the 60 mm standard maximum for this 16 mm bore, it is produced as a made-to-order item. End-stopping relies on a fixed NBR bumper rather than an adjustable cushion.

Uses the male M5 rod end to push separated circuit boards out of a routing fixture, capitalizing on the short body length to fit within dense electronics assembly machinery.
Actuates a folding arm on a compact packaging line to tuck flaps prior to sealing, operating efficiently at 30-500 mm/s within tight conveyor side frames.
Drives a 65 mm shift cycle to advance microplate trays in analytical instruments, utilizing the built-in magnet to confirm stroke completion with a solid-state switch.
When sizing this actuator, you can step down to the SDA12 which yields 56.5 N of push at 0.5 MPa, or move up to the SDA20 which provides 157.1 N at the same pressure. To order accurately, confirm the 16 mm bore, 65 mm non-standard stroke, M5x0.8 air port, male M5x0.8 rod thread, and the required magnetic switch slot.
Keep in mind that a standard compact cylinder cannot hold a load if air pressure drops or the valve is centered; the piston will drift. The fixed NBR bumper only decelerates the stroke near its ends and does not act as a locking brake. For suspended loads, incorporate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting cylinder generates 100.5 N push and 86.4 N pull at 0.5 MPa, and 140.7 N push with 121 N pull at 0.7 MPa. The theoretical maximum push is 21 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, withstands 1.5 MPa proof pressure, and runs at speeds from 30-500 mm/s.
No, it uses a fixed NBR bumper at each end to decelerate the piston, which is not field-adjustable. Because the 65 mm stroke exceeds the 60 mm standard maximum for a 16 mm bore, it is a non-standard made-to-order part; for high-energy cycles, add an external shock absorber.
