SBA60 belt actuators (NEMA 23)
The SBA60 is the workhorse of the belt line: NEMA 23 motors, a wider profile, and travels of 250, 500, and 750 mm in the motor-up configuration, plus 365 and 545 mm absolute-encoder SBAC60 motor-down units. When a request outgrows the SBA45 on payload or travel, this is where the engine lands.
The direct-drive stepper runs to 850 mm/s and the servo to 1,500 mm/s. With the 3:1 planetary gearbox the catalog rating is 10 kg at 250 mm/s, which covers most tooling heads, dual grippers, and dispensing valves. Pricing starts at $1,250 for the SBAC60 365 mm stepper and $1,350 for the SBA 60 250 mm motor-up stepper; the 750 mm servo with gearbox tops the family at $2,200.
Motor up or motor down
Motor-up places the motor above the profile at the drive end, keeping the footprint short along the axis; motor-down folds it under for a low profile where height is constrained. Both are the same actuator mechanically. The engine picks the orientation that clears the adjacent axes in the assembly and shows it in the 3D view before you quote.

Rated load and speed are catalog maximums for the configuration shown; "—" means the figure depends on the motor curve at your speed — the engine computes it. All prices are U.S. list, single quantity.

Describe the task — payload, travel, speed, orientation. The engine picks the family and the variant, shows the torque and inertia math, and prices the whole system.
Frequently asked
What payload can an SBA60 move?
10 kg rated with the 3:1 gearbox at 250 mm/s; at a 2× safety factor plan on about 5 kg of moving mass, or more at lower speed. The engine computes the exact margin from the torque curve.
Longest SBA60?
750 mm stock in the motor-up configuration. Longer spans move to the SBA90 at 1,275 mm or an engineered tandem-rail system.
Does the SBA60 come with an absolute encoder?
Yes — the SBAC60 365 mm and 545 mm motor-down units, stepper or servo, with or without gearbox.
