The AirTAC AirTAC SDA16X15BH 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 SDA16X15BH is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. Its short riveted assembly integrates the barrel, rear cover, piston, and rod to drastically reduce axial mounting depth compared to round-body units. Delivering 100.5 N of push force at 0.5 MPa, it features a hard-anodized bore and a two-way piston seal for reliable pneumatic actuation.
This specific configuration includes a male M5x0.8 threaded piston rod for direct load coupling, paired with high-temperature fluororubber (FKM) seals. The end caps use fixed NBR bumpers to decelerate the stroke endpoints rather than adjustable air cushions. Because this SKU lacks the -S magnet option, it cannot host reed or electronic switches; position sensing requires the -S variant instead.

Uses the 15 mm stroke to push singulated circuit boards out of routing fixtures, where the compact 16 mm body saves valuable Z-axis height on the router bed.
Applies 100.5 N of clamping force at 0.5 MPa to hold card and plastic layers together, leveraging the FKM seals to withstand ambient heat from the sealing platen.
Actuates a small pinch valve for fluid routing, taking advantage of the male M5x0.8 rod end for secure mechanical coupling to the valve pinch mechanism.
When sizing this 16 mm bore actuator, evaluate your force margins carefully. Stepping down to the SDA12 yields 56.5 N of push at 0.5 MPa, whereas moving up to the SDA20 provides 157.1 N. At 100.5 N push (@0.5 MPa), this model offers a safe working load of roughly 60 N (about 60% capacity) and a vertical lift capacity near 5.1 kg with a 2:1 safety margin. Keep in mind that a standard compact cylinder drifts when air pressure is lost or the valve is centered—the fixed bumper only decelerates near stroke end, so holding a suspended load requires an external rod lock or pilot-operated check valve. To order, confirm the 16 mm bore, 15 mm stroke, M5x0.8 port, male M5x0.8 rod thread, and FKM seal specifications.
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 on filtered air between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and sustains speeds of 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot trigger reed or electronic switches. You must select the -S option (e.g., SDA16X15BHS) to enable position sensing. Additionally, note that this unit uses fixed NBR bumpers for end-stop deceleration rather than adjustable air cushions, so external shock absorbers are recommended for high-speed operations.
