The AirTAC AirTAC SDA16X25B Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 25mm 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 SDA16X25B is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly reduces overall length compared to round-body units, yielding a theoretical push force of 100.5 N at 0.5 MPa (140.7 N at 0.7 MPa) over a 25 mm travel. This specific SKU features a male M5x0.8 piston rod thread for direct load coupling.
The 16 mm bore utilizes an M5x0.8 air port and a hard-anodized inner wall to minimize friction. End-stopping relies on fixed NBR bumpers rather than adjustable cushions, meaning high-speed approaches may require external shock absorption. Note that this configuration omits the piston magnet, so position sensing is not supported without the -S option.

Drives short 25 mm vertical strokes for electronic component placement heads where axial space is severely restricted.
Applies a 60 N tamping force to press adhesive labels onto cartons without requiring a large pneumatic footprint.
Moves sample trays in diagnostic equipment, utilizing the 16 mm bore's compact body to fit within dense instrument chassis.
When sizing this 16 mm bore unit, consider stepping down to the SDA12 which provides 56.5 N push at 0.5 MPa, or moving up to the SDA20 which yields 157.1 N at the same pressure. Based on the 100.5 N output, a safe working load is approximately 60 N, translating to a vertical lift capacity near 5.1 kg with a 2:1 safety margin.
To finalize your order, confirm the 16 mm bore, 25 mm stroke, M5x0.8 port, and the male M5x0.8 rod thread (-B). Because a standard double-acting cylinder vents on air loss, an external rod lock or pilot-operated check valve is necessary if the load must be prevented from drifting.
Quick checklist
This 16 mm bore cylinder generates a push force of 100.5 N and a pull force of 86.4 N at 0.5 MPa. At 0.7 MPa, push increases to 140.7 N. The theoretical maximum push is 21 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 internal piston magnet, so it cannot trigger AirTAC reed or electronic switches. You must select the -S option code to enable sensing. Additionally, end-of-stroke deceleration is handled by fixed NBR bumpers, not an adjustable air cushion.
