The AirTAC SDA20X15BH Compact Cylinder | 20mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø20mm bore and 15mm 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 SDA20X15BH is a double-acting single-rod compact cylinder engineered for tight axial spaces. It delivers 157.1 N of push force at 0.5 MPa and 219.9 N at 0.7 MPa. The riveted unibody design drastically reduces mounting depth compared to round-body units, making it ideal for dense machinery layouts. This specific SKU includes an FKM fluororubber seal for enhanced thermal and oil resistance.
This model features an 8 mm piston rod with a male M6x1.0 thread end for straightforward load coupling. Because it lacks the -S magnet code, it cannot host reed or electronic switches. End-of-stroke deceleration is handled by fixed NBR bumpers rather than adjustable air cushions, meaning operators should slow high-velocity approaches or add external shock absorbers to mitigate impact energy.

Actuates a routing blade in a PCB depaneling machine where the short 15 mm stroke and compact body fit within tight router enclosures, utilizing the FKM seals to resist flux residues.
Provides the 157.1 N push force required to close a small heated platen on a pharmaceutical blister packaging line, with the male M6 thread securing the upper die.
Presses surface-mount connector pins flat during electronics assembly, taking advantage of the 8 mm rod and fixed NBR bumpers to absorb the tiny 15 mm end-stop impact.
When sizing this actuator, stepping down to the SDA16 yields 100.5 N of push at 0.5 MPa, while stepping up to the SDA25 provides 245.4 N, allowing you to scale force precisely. Keep in mind that a standard compact cylinder will drift and cannot hold a load if air pressure drops or the valve is centered; utilize an external rod lock or pilot-operated check valve if position holding is mandatory. Confirm your ordering essentials: 20 mm bore, 15 mm stroke, M5x0.8 port, male M6 rod thread, FKM seals, and no sensor magnet.
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 0.15-1.0 MPa at speeds of 30-500 mm/s, with a proof pressure of 1.5 MPa.
No, this specific SKU lacks the internal piston magnet, so it cannot host reed or electronic switches. You would need the -S option for sensing. Additionally, it uses fixed NBR bumpers for end-stop deceleration rather than an adjustable air cushion, so external shock absorbers are recommended for high-energy loads.
