Key Features
High Precision
Manufactured with tight tolerances, the Super Precision BTM85 B/P4CDBA bearing is manufactured by SKF to ensure a consistently high rotational accuracy and optimal performance.
Double Directional Loads
Capable of handling axial loads in both directions, the BTM85B/P4CDBA Super Precision Angular Contact Thrust Bearing has a double direction design which provides enhanced versatility and reliability in machinery.
Angular Contact Design
The BTM85 B/P4CDBA bearing is made up of two non-separable Single Row Angular Contact Bearings in a back-to-back arrangement and are designed to accommodate axial loads in both directions while providing a high degree of system rigidity. They have a 40° contact angle which can operate at much higher speeds than bearings with a 60° contact angle.
