The AirTAC SDA16X55B Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 55mm 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 SDA16X55B is a double-acting single-rod compact cylinder engineered to deliver 100.5 N of push force and 86.4 N of pull force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into a highly shortened unit, saving valuable axial mounting depth where a standard round-body actuator simply cannot fit. The internal bore is hard-anodized and employs a two-way piston seal for reliable low-friction operation.
This specific configuration includes a male M5x0.8 piston rod thread (denoted by the B option) for secure mechanical coupling to your load, alongside a fixed M5x0.8 air port. Because this SKU lacks the S magnet suffix, it cannot host magnetic position sensing. End-of-stroke deceleration is handled purely by fixed NBR bumpers rather than adjustable cushions, meaning operators should reduce approach speeds or add external shock absorbers for high-energy loads.

Provides the precise 100.5 N extension needed to press and stabilize circuit boards during automated routing and depaneling processes.
Actuates a lightweight routing gate on a packaging conveyor, utilizing its 55 mm stroke and compact riveted body to fit within tight transfer gaps.
Pushes processed test tubes or vials out of a centrifuge carousel using its male M5x0.8 threaded rod end to mount a custom soft-tip ejector.
When sizing this 16 mm bore actuator, consider stepping down to the SDA12, which yields 56.5 N of push at 0.5 MPa, or moving up to the SDA20, which provides 157.1 N. Be aware that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end rather than locking the rod. For suspended or gravity-loaded applications, integrate an external rod lock or pilot-operated check valve. Ensure your ordering essentials match the 16 mm bore, 55 mm stroke, M5x0.8 port, male M5x0.8 rod thread, and no sensor magnet.
Quick checklist
This double-acting cylinder generates 100.5 N push and 86.4 N pull at 0.5 MPa, increasing to 140.7 N push and 121 N pull at 0.7 MPa. The theoretical maximum push force is 21 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and functions safely in temperatures from -20 to +70 C at speeds of 30-500 mm/s.
No, it uses fixed NBR bumpers at each end to decelerate the stroke, which cannot be field-adjusted; external shock absorbers are recommended for high-speed cycling. Additionally, because this SKU lacks the S magnet option, it cannot support AirTAC reed or electronic switches.
