The AirTAC AirTAC SDA25X50B Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 50mm 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 SDA25X50B is a double-acting, single-rod compact cylinder engineered to deliver 245.4 N of push force and 206.2 N of pull force at 0.5 MPa. Its riveted assembly joins the barrel, rear cover, piston, and rod into a highly shortened unit, saving valuable axial mounting depth where a conventional round-body actuator simply will not fit. The 25 mm bore features a hard-anodized inner wall and operates at speeds between 30 and 500 mm/s.
This specific SKU includes the -B option, meaning it uses a male M8x1.25 threaded piston rod end for direct load coupling, rather than the default female M5x0.8. End-of-stroke deceleration is handled by a fixed NBR bumper at each end, which is not an adjustable air cushion. Because this configuration lacks the -S magnet option, it cannot host AirTAC reed or electronic switches.

Shifts a drill head guide rail in electronics manufacturing, using the 245.4 N extend force to positively locate the spindle without consuming excessive Z-axis footprint.
Drives a mechanical flap folder on a packaging line, where the fixed NBR bumper safely absorbs the 50 mm stroke impact and the male M8x1.25 rod threads directly into the linkage.
Actuates a routing diverter on a beverage conveyor, providing rapid 30-500 mm/s motion to guide plastic bottles into separate labeling lanes.
When sizing this actuator, consider stepping up or down based on your force requirements: the smaller SDA20 provides 157.1 N of push at 0.5 MPa, while the larger SDA32 offers 402.1 N at the same pressure. At 0.5 MPa, this 25 mm bore yields a safe working load of roughly 147 N (about 60 percent of its push force) and can vertically lift approximately 12.5 kg with a 2:1 safety margin. To finalize your order, confirm the 50 mm stroke, the M5x0.8 air port, the male M8x1.25 rod thread, and that no sensor magnet is required. If your application must hold a load without live pressure, note that the piston will drift on air loss; an external rod lock or pilot-operated check valve is required for secure positioning.
Quick checklist
At 0.5 MPa, the push force is 245.4 N and the pull force is 206.2 N. At 0.7 MPa, the push force is 343.6 N and the pull force is 288.6 N. The theoretical maximum push force is 50 kgf at the 1.0 MPa operating pressure limit.
No, this specific SKU does not include the -S magnet option, so it cannot host AirTAC reed or electronic switches. You would need to specify an SDA25X50BS variant to gain the internal piston magnet required for sensing along the body grooves.
