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 two nut configurations—cylindrical or flanged—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). The nut features 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 nut 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.
