Key Features
High Precision
Manufactured with tight tolerances, the Super Precision BTW70 CTN9/SP 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 BTW70CTN9/SP Super Precision Angular Contact Thrust Bearing has a double direction design which provides enhanced versatility and reliability in machinery.
Angular Contact Design
The BTW70 CTN9/SP bearing is made up of two separable Single Row Angular Contact Thrust Ball Bearings with a 60° contact angle in a back-to-back arrangement. Configured in this way, and with the large number of balls the bearings contain, means these bearings can accommodate heavy axial loads in both directions while providing a high degree of system rigidity.
