Fafnir® Single Row Ball Screw Support Bearings (MM-BS)
Precision Ball Bearings
Timken® angular contact ball bearings are designed for combination radial and axial loading. Single-row bearings have high thrust capacity in one direction. Some single-row bearings are specifically designed for duplex mounting in sets for maximum performance.
