The AirTAC AirTAC SDA16X35SB Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 35mm 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 SDA16X35SB is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly integrates the barrel, rear cover, and piston to drastically reduce axial mounting depth compared to round-body units. Delivering 100.5 N of push force at 0.5 MPa, it handles light-duty positioning with a 6 mm piston rod and an M5x0.8 air port.
This specific configuration includes a built-in piston magnet (S) for direct mounting of AirTAC reed or electronic switches along the body grooves. It also features a male-thread M5x0.8 piston rod end (B), offering a straightforward mechanical coupling for tooling. The bore interior is hard-anodized, and end-of-travel deceleration is managed strictly by a fixed NBR bumper rather than an adjustable air cushion.

Provides the 100.5 N push force needed to eject populated printed circuit boards from test fixtures, utilizing the short 35 mm stroke to minimize Z-axis height.
Actuates folding mechanisms on compact packaging lines where axial space is restricted, using the male M5x0.8 rod thread to secure custom folding arms.
Shifts micro-fluidic dispenser heads vertically with a safe working load near 60 N, relying on the built-in magnet to trigger electronic reed switches for precise dosing stops.
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 at 0.5 MPa. Based on the 100.5 N output at 0.5 MPa, the safe working load is approximately 60 N (about 60% of capacity), translating to a vertical lift capability of roughly 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 directional valve is centered; the fixed NBR bumper only decelerates the stroke end and does not function as a locking brake. For applications requiring suspended load holding, an external rod lock or pilot-operated check valve is necessary. To order, confirm the 16 mm bore, 35 mm stroke, M5x0.8 port, male M5x0.8 rod thread, and the integrated magnet.
Quick checklist
At 0.5 MPa, the push force is 100.5 N and the pull force is 86.4 N. At 0.7 MPa, the push force is 140.7 N and the pull force is 121 N. The theoretical maximum push force is 21 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a speed range of 30-500 mm/s.
It uses a fixed NBR bumper at each end to decelerate the piston near the stroke limits; it is not an adjustable air cushion. Additionally, the bumper does not lock the piston, so the cylinder cannot hold a load if air pressure is lost. For vertical load holding, you must add an external rod lock or pilot-operated check valve.
