DBA 60 575mm Dual Carriage Belt Actuator

DBA 60 575mm Dual Carriage Belt Actuator is a LYNX DBA 60 dual-carriage actuator with 575 mm of travel and a NEMA 23 stepper motor. List price $2,250, 2-3 weeks lead time.

Two independently driven carriages on one rail with collision avoidance; 2.5 kg per carriage.

How the engine sizes it

Every build runs this actuator through the deterministic sizing engine: payload-at-speed against the family envelope, a 2× load safety factor as a hard gate, and the motor checked for at least 25% torque margin at your commanded speed on real torque-curve data (stepper pull-out curves at 24 V). Inertia mismatch above 10:1 triggers a computed gearbox remedy. The result ships with the math shown.

Ask for it by name in the engine, or describe the task and let the engine decide whether this is the right part — it will tell you if a smaller or larger variant fits better, and why.
