The AirTAC AirTAC SDA20X10SBH Compact Cylinder | 20mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø20mm bore and 10mm 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 SDA20X10SBH is a double-acting single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly minimizes axial mounting depth where standard bodies fail to fit. Delivering 157.1 N of push force at 0.5 MPa, it features an 8 mm piston rod and M5x0.8 porting. This specific configuration includes a male M6x1.0 rod end, a piston magnet for position sensing, and fluororubber (FKM) seals for enhanced thermal and oil resistance.
Integrated grooves allow the mounting of AirTAC reed or electronic switches to track the 10 mm travel. Instead of an adjustable air cushion, the unit relies on a fixed NBR bumper to decelerate the piston at stroke extremes. Buyers should note that a standard compact actuator like this will drift if air pressure drops; maintaining a vertical load requires an external pilot-operated check valve or rod lock.

Provides precise 10 mm lateral shifting of printed circuit boards on a pick-and-place conveyor using the male M6 rod end for secure tooling attachment.
Drives a short-stroke sealing jaw in a vertical form-fill-seal machine, where the FKM seals withstand localized heat and packaging lubricants.
Taps a micro-fluidic dispenser nozzle against a vial opening, utilizing the compact riveted body to fit within dense laboratory automation racks.
When sizing this 20 mm bore unit, evaluate your force margins carefully. Stepping down to the SDA16 reduces the 0.5 MPa push capacity to 100.5 N, while moving up to the SDA25 increases it to 245.4 N. For the SDA20X10SBH, a safe working load is approximately 94 N (about 60% of the 157.1 N figure), translating to a vertical lift capability of roughly 8 kg with a 2:1 safety margin. Ensure your ordering essentials match the exact code: 20 mm bore, 10 mm stroke, M5x0.8 port, male M6 rod thread (B), magnet (S), and FKM seals (H).
Quick checklist
This double-acting cylinder generates 157.1 N push and 131.9 N pull at 0.5 MPa, and 219.9 N push at 0.7 MPa. The theoretical maximum push force is 32 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, runs at 30-500 mm/s, and functions in -20 to +70 C temperatures.
It uses a fixed NBR bumper to decelerate the piston near the stroke ends, which is not an adjustable air cushion. Additionally, it does not hold position naturally; if air is lost, the piston drifts. To suspend a load safely, you must install an external rod lock or a pilot-operated check valve.
