51100 & 51000 Series Single Direction Thrust Ball Bearings

The 51100 and 51000 series represent the lightest range of single direction thrust ball bearings. Characterized by their thin cross-sections and minimal weight, these bearings are ideal for applications with limited axial space. They provide precise axial support for rotating components in precision instruments and light industrial machinery.
