BSR Miniature Ball Screws from PBC Linear represent a major advancement in precision linear motion technology. Designed and manufactured in the USA, these assemblies are available with three nut configurations—cylindrical, flanged, and threaded cylindrical—and two nut fits – standard and transitional - offering flexibility to suit a variety of mounting requirements. Available in six metric size combinations (diameter × lead), they provide a compact and efficient solution for a wide range of applications.
Each unit is engineered for exceptional durability and performance, with static axial load capacities up to 2.144 kN (482 lb). All nuts feature an integrated multi-liner ball return system that ensures smooth, efficient recirculation of the balls, enhancing overall motion precision and reliability. Polymer wipers at both ends of the flanged and cylindrical nuts protect against debris ingress and help maintain system integrity. Ideal for applications requiring precise linear motion within a compact footprint, BSR Miniature Ball Screws deliver flexibility, reliability, and high performance in demanding environments, and are available in Grade 5, 7, or 10 accuracy.
