NSK’s MBSA Series combines a precision ground ball screw with a NEMA stepping motor. This innovative new product delivers a compact, space-saving design eliminating the need for motor couplings. Superior to a lead screw, the precision ground ball screw offers higher efficiency, lower friction, smoother operation, no backlash, improved rigidity and longer life. It is designed to accommodate a configurable encoder mounted to the back of the stepping motor that can communicate with a wide variety of controllers/drivers. Customers can select the controller/driver of their choice.
MBSA Series will be available in January 2017. Customers can choose from a standard size range of NEMA motors including: 14, 17 or 23. Custom designs options are available for smaller motor requirements. Standard ball screws sizes will range in diameter from 6mm to 8mm and a lead range of 1mm to 2mm to allow for more precise positioning.
