The AirTAC SDA20X10H 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 SDA20X10H is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly reduces overall axial length, fitting easily where round-body units fail. This specific SKU features a fluororubber (FKM) seal for heightened oil and thermal resistance, delivering 157.1 N of push force at 0.5 MPa.
Equipped with an 8 mm piston rod and an M5x0.8 port, the unit operates at speeds between 30-500 mm/s. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Note that this configuration lacks a piston magnet, so it cannot support magnetic sensing without the -S option.

Provides the short 10 mm clamping stroke needed to secure circuit boards during router cutting, utilizing the FKM seal to resist flux-contaminated environments.
Applies 157.1 N of precise extend force to close heated sealing jaws on pharmaceutical blister packs within confined machine frames.
When sizing this 20 mm bore actuator, consider stepping down to the SDA16 (100.5 N push @0.5 MPa) for lighter duties, or up to the SDA25 (245.4 N push @0.5 MPa) if your application demands greater thrust.
For ordering, confirm the 20 mm bore, 10 mm stroke, M5x0.8 port, FKM seal, and female M4x0.7 rod thread. Remember that a standard compact cylinder drifts if air pressure drops or the valve centers; the fixed bumper only slows the piston near stroke end. To hold a load securely without live pressure, integrate an external rod lock or pilot-operated check valve.
Quick checklist
This 20 mm bore 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. Operating pressure ranges from 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
No, this specific SKU does not include a piston magnet, so it cannot trigger AirTAC reed or electronic switches. You must select the -S option code to enable sensing. Additionally, end stops rely on a fixed NBR bumper, not an adjustable air cushion.
