The AirTAC Airtac B06-SDA Battery Dedicated Cylinder B06-SDA25X20B is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 20mm 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 B06-SDA25X20B is a double-acting, single-rod compact cylinder engineered for battery-manufacturing lines. The leading B06- prefix designates this as a battery-industry dedicated variant of the base SDA25X20B, meaning it is mechanically identical to the standard model. It delivers 245.4 N of push force and 206.2 N of pull force at 0.5 MPa. Its short, riveted body assembly significantly reduces axial mounting depth, saving valuable footprint space in dense cell assembly machinery.
This specific configuration features a male-thread piston rod end (M8x1.25) for secure mechanical load coupling, paired with a 10 mm rod diameter. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Note that this SKU lacks a piston magnet; adding an S option is required to utilize the body sensor grooves with reed or electronic switches.

Drives the precision stacking of battery anodes and cathodes, utilizing the 20 mm stroke and 245.4 N force to press separator sheets without damaging delicate cell materials.
Applies consistent clamping pressure on busbar tabs during laser welding, using the male M8x1.25 rod end to secure the welding fixture head in automated pack assembly lines.
Actuates a diverter gate on a conveyor system to route finished pouch cells into quality testing channels, benefiting from the short riveted body to fit within tight machine guarding.
When sizing this actuator, compare its 245.4 N push force at 0.5 MPa against adjacent bores: stepping down to the SDA20 yields 157.1 N, while stepping up to the SDA32 provides 402.1 N. Based on the 245.4 N output, the safe working load is approximately 147 N (about 60% capacity), which translates to a vertical lift capability of roughly 12.5 kg with a 2:1 safety margin. To finalize your order, confirm the 25 mm bore, 20 mm stroke, M5x0.8 port, male M8x1.25 rod thread, and the absence of a sensor magnet.
Keep in mind that a standard compact cylinder cannot hold a load if air pressure drops or the valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the stroke near its ends rather than acting as a locking brake. For battery-handling applications requiring suspended load holding, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 25 mm bore double-acting cylinder provides a push force of 245.4 N and a pull force of 206.2 N at 0.5 MPa. At 0.7 MPa, the push force is 343.6 N. The theoretical maximum push force is 50 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
The B06- prefix indicates this is an AirTAC battery-manufacturing dedicated variant of the SDA25X20B, sharing identical physical specs and dimensions. It does not have an adjustable air cushion; instead, it uses a fixed NBR bumper at each end to absorb end-stop impact. For high-speed operations, consider adding external shock absorbers.
