The AirTAC AirTAC SDA16X55SB 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 SDA16X55SB is a double-acting 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, and piston into a highly space-efficient unit, saving valuable axial mounting depth in tight machinery layouts. The bore is hard-anodized and utilizes a two-way seal for reliable pneumatic performance.
This specific configuration includes a built-in piston magnet (S) for direct mounting of AirTAC reed or electronic switches along the body grooves, plus a male M5x0.8 threaded rod end (B) for secure mechanical coupling. It operates at speeds from 30-500 mm/s, relying on fixed NBR bumpers to decelerate the stroke ends rather than adjustable cushions. The 55 mm stroke represents the maximum standard extension for this 16 mm bore size.

Provides the 100.5 N push stroke needed to eject freshly routed circuit boards from a depaneling fixture without stressing the 55 mm travel distance.
Utilizes the male M5x0.8 rod end to securely attach a folding arm, tucking flaps on compact packaging lines where axial mounting depth is severely restricted.
Pairs with an AirTAC electronic switch via the built-in magnet to verify the 55 mm stroke position when pushing test tube racks into a diagnostic analyzer.
When sizing this 16 mm bore actuator, consider stepping down to the SDA12 if your application requires less than 56.5 N of push force at 0.5 MPa, or moving up to the SDA20 if you need the 157.1 N output of the next larger bore. For the SDA16X55SB, the computed safe working load is approximately 60 N (about 60% of its 100.5 N capacity), making it suitable for a vertical lift of roughly 5.1 kg with a 2:1 safety margin. Confirm your ordering essentials: 16 mm bore, 55 mm stroke, M5x0.8 air port, male M5x0.8 rod thread, and the integrated magnet.
Keep in mind that a standard double-acting cylinder does not hold its position if air pressure is lost or the directional valve is centered; the piston will drift. The fixed NBR bumper only decelerates the load near the stroke end and acts as neither a lock nor a brake. If your setup demands strict position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting 16 mm bore 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 within a pressure range of 0.15-1.0 MPa at speeds between 30-500 mm/s.
It uses fixed NBR bumpers at both ends to decelerate the piston; these are not field-adjustable air cushions, so you should slow the approach or add an external shock absorber for high-energy loads. Additionally, the -B option specifies a male M5x0.8 threaded piston rod, replacing the default female M3x0.5 thread for direct load attachment.
