Angular Contact Thrust Ball Bearings

"NSK Angular Contact Thrust Ball Bearings are the Superior high-speed capability and high rigidity bearings. This fulfills the requirements of sustaining axial loads in machine tool spindles. For such types of requirements, NSK offers three types of bearings for customers. And they can choose it based on the structure and the characteristics of their machine. All of these bearings are designed to use in the combination of cylindrical roller bearings. These bearings are manufactured with special outer ring diameter tolerances to provide clearance between the outer diameter of the bearing and the inner diameter of the housing when mounted so that any radial load is supported by the cylindrical roller bearings only. The high-speed angular contact thrust ball bearings of the NSKROBUST series are capable of high-speed performance while maintaining high rigidity. Contact angles of 40° (BTR) and 30° (BAR) result in superior high-speed performance and low heat generation."
