Ball Screw Linear Actuators with NEMA Motors

Miniature ball screw actuator assemblies of the BS Series combine a precision ball screw, nut, and NEMA motor into a compact, high-performance linear motion solution. These actuators are available in five NEMA frame sizes — 08, 11, 14, 17, and 23 — with screw diameters ranging from 6 mm to 10 mm depending on the motor size and configuration. They are offered with both flanged and cylindrical nut styles to suit different mounting requirements. A preload option is available for applications that demand higher rigidity and superior positional accuracy. Polymer wipers at each end of the nut effectively prevent the ingress of debris and particulates, helping maintain smooth, long-term operation. Standard and custom-machined journals are available, supporting fixed or floating bearing configurations. Fixed and floating end blocks are also offered, providing flexibility for a wide variety of installation needs. For applications requiring more flexibility, the BE Series offers a highly customizable version of these integrated ball screw actuators in the same screw diameter range and five NEMA frame sizes, with multiple motor lengths, a wider range of leads, and various nut options to better match specific force, speed, and positioning requirements.
