ULTAGE 79U and 70U series bearings were developed from standard angular contact ball bearings (79 and 70). Optimized internal design and adoption of a new resin cage allows high-speed operation and ensures high rigidity. ■Features 1. Optimized internal design enables high-speed operation and high rigidity. 2. A new resin cage enables improvement in grease retention for grease lubrication and enhanced performance in feeding and discharge of oil for air-oil lubrication. 3. Bearings are available with either steel or ceramic balls. 4. Three contact angles (15°, 20°, and 30°) are available to handle a wide range of applications.
