BSA 60 250mm Inline Stepper
BSA 60 250mm Inline Stepper is a BSA ball-screw linear actuator with 250 mm of travel and a NEMA 23 stepper motor. List price $1,475, 2-3 weeks lead time.
Screw lead options
The lead is selected at order; the price is the same for every lead. The engine maps your target speed to the lead and checks the payload margin that remains.
| Lead | Max speed | Rated load |
|---|---|---|
| 5 mm/rev | 100 mm/s | 15 kg |
| 10 mm/rev | 200 mm/s | 15 kg |
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.
