The AirTAC SDA20X10BH 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 SDA20X10BH is a double-acting, single-rod compact cylinder engineered for tight axial spaces. A riveted assembly joining the barrel, rear cover, and piston yields a very short overall length, saving valuable mounting depth where a round-body unit would protrude. At 20mm bore, it generates 157.1 N of push force and 131.9 N of pull force at 0.5 MPa.
This specific SKU includes a male M6x1.0 piston rod thread for direct load coupling and utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance. End-stopping relies on a fixed NBR bumper that decelerates the piston near stroke end; it is not an adjustable air cushion. Because this configuration lacks the -S magnet option, it cannot host AirTAC reed or electronic switches.

Provides the short 10mm clamping stroke to secure circuit boards during routing, with FKM seals resisting flux residue and ambient heat.
Actuates a small heated platen in a packaging line where the compact riveted body minimizes machine footprint and the male M6 rod secures the tooling.
Toggles a precision fluid dispense valve for reagents, using the 157.1 N push force to overcome fluid pressure without excessive bulk.
When sizing this 20mm bore, stepping down to the SDA16 yields 100.5 N of push force at 0.5 MPa, while stepping up to the SDA25 provides 245.4 N. To finalize your order, confirm the 10mm stroke, M5x0.8 port, male M6x1.0 rod thread, and FKM seal. Note that a standard cylinder drifts if air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a locking brake. To hold a load securely without live pressure, incorporate an external rod lock or a pilot-operated check valve.
Quick checklist
This 20mm bore double-acting cylinder outputs 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. Operating pressure ranges from 0.15 to 1.0 MPa, with a speed of 30-500 mm/s.
No, this specific SKU lacks the -S piston magnet, so it cannot host AirTAC reed or electronic switches. Additionally, it uses a fixed NBR bumper to decelerate the stroke end rather than an adjustable air cushion; for high-speed cycles, you should slow the approach or add an external shock absorber.
