Radial Ball Bearings: When axial force in both directions is needed and speed isn’t the most important factor for your application, then radial ball bearings are usually selected. These high precision bearings usually don’t need to be purchased in sets for preload.

Precision ball bearings are used for high precision applications in a variety of markets, including aerospace, health, machine tool, robotics and general industry.Precision ball bearings are used for high precision applications in a variety of markets, including aerospace, health, machine tool, robotics and general industry. MM/MMV (Machine Tool Bearings) Super precision bearings manufactured to MM/MMV tolerances combine the accuracy and performance of ABEC 9/ISO P2 with the non-critical features of ABEC 7/ISO P4 levels for cost effectiveness.Precision Bearings Ultra-precision equipment requires more than standard bearings can deliver. Our extensive range of Timken ® precision bearing assemblies, designed for the critical tolerances demanded by precise applications, offer superior rotational accuracy, consistency and rigidity.
