Miniature Metric Ball Screw Assemblies

Miniature Metric Ball Screw Assemblies

Excellent performance in small-scale applications

The BSR Miniature Metric Ball Screw assemblies with Cylindrical and Flange Nuts by PBC Linear represent a significant advancement in precision linear motion technology. Designed and manufactured in America, these ball screw assemblies are available in five metric sizes (diameter x lead), offering a compact and efficient solution for a wide range of applications. 

With a static axial load capacity up to 2.144 kN (482 lb.), these units are engineered for durability and performance. The use of a multi-liner ball return system enhances their efficiency, with polymer wipers at each end of the nut to prevent debris ingress, maintaining the system's integrity. The cylindrical nut option provides for a more compact assembly while flange nuts provide ease of installation and removal.

These BSR Miniature Metric Ball Screw assemblies are ideal for applications requiring precise linear motion in a compact footprint, offering both flexibility and high performance in demanding environments.
