The 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. 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.
