The AirTAC SDA16X45BH Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 45mm 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 SDA16X45BH is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly minimizes axial mounting depth while delivering 100.5 N of push force and 86.4 N of pull force at 0.5 MPa. This specific SKU includes a male M5x0.8 threaded piston rod for direct load coupling and utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance.
The 16 mm bore features an M5x0.8 air port and a 6 mm rod diameter. End-stop deceleration relies on fixed NBR bumpers rather than an adjustable air cushion, meaning external shock absorbers should be added for high-energy cycles. Because this configuration lacks the -S magnet option, it cannot support magnetic position sensing.

Provides the 100.5 N extension stroke needed to push singulated circuit boards out of routing fixtures without stressing the 6 mm male rod.
Utilizes FKM seals to withstand ambient heat from sealing bars while maintaining a precise 45 mm stroke for card alignment.
Drives a metering valve in compact analytical equipment where axial space is restricted and consistent 86.4 N retract force is required.
When sizing this 16 mm bore actuator, evaluate your force margins carefully. Stepping down to the SDA12 reduces the push output to 56.5 N at 0.5 MPa, while stepping up to the SDA20 increases it to 157.1 N. Confirm your ordering essentials: 16 mm bore, 45 mm stroke, M5x0.8 port, male rod thread (B), and FKM seals (H). Note that this cylinder cannot hold a load if air pressure drops; the piston will drift, requiring an external rod lock or pilot-operated check valve for fail-safe positioning.
Quick checklist
This 16 mm bore 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 is 21 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, handles speeds of 30-500 mm/s, and functions in temperatures from -20 to +70 C.
No, this specific SKU lacks the -S magnet option, so it cannot trigger AirTAC reed or electronic switches. Additionally, end-stop deceleration is handled by fixed NBR bumpers rather than an adjustable cushion, so you must control the approach speed externally for heavy or fast-moving loads.
