The AirTAC AirTAC SDA20X10N 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 SDA20X10N is a double-acting, single-rod compact cylinder engineered for tight axial spaces. It delivers 157.1 N of push force and 131.9 N of pull force at 0.5 MPa, making it suitable for light-duty positioning. The hard-anodized bore and two-way piston seal ensure reliable service within its 30-500 mm/s speed range.
This model features a 10 mm stroke and an 8 mm piston rod with a female M4x0.7 thread. Its riveted body drastically reduces mounting depth compared to round-body alternatives. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable cushion. Note that this specific SKU lacks a piston magnet, so it cannot directly host AirTAC reed or electronic switches.

Uses the 10 mm stroke to nudge printed circuit boards into alignment on an SMT pick-and-place conveyor without taking up valuable mounting length.
Provides a quick 157.1 N tap to separate cut packaging film sections on a high-speed flow wrapper prior to the sealing jaw.
Pushes lightweight plastic or electronic components from a vibratory bowl feeder into a machining chuck using minimal axial footprint.
When sizing this 20 mm bore actuator, consider stepping down to the SDA16, which provides 100.5 N of push at 0.5 MPa, or stepping up to the SDA25, which yields 245.4 N. Based on the 157.1 N output, the safe working load is roughly 94 N, allowing a vertical lift of about 8 kg with a 2:1 safety margin. To finalize your order, confirm the 10 mm stroke, M5x0.8 port, female rod thread, and the absence of a sensor magnet.
Keep in mind that a standard compact cylinder will drift and cannot hold a load if air pressure drops or the valve is centered. The fixed NBR bumper only slows the piston near stroke end and does not function as a locking brake. If your application requires position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
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 on filtered air between 0.15 and 1.0 MPa.
No, this model uses a fixed NBR bumper at each end to decelerate the stroke, not a field-adjustable air cushion. Additionally, this SKU lacks the internal piston magnet, so it cannot support reed or electronic switches; you would need the -S option for sensing.
