NSKROBUST Ultra High-Speed Angular Contact Ball Bearings

NSKROBUST angular contact ball bearings are designed to support higher machining capacity with ultra high-speed rotation, achieving superior precision-machined surfaces while operating with thermal robustness, low heat generation, low seizure rates and low noise.

NSKROBUST Ultra High-Speed Angular Contact Ball Bearings

Design Features

  • Special design angular contact ball bearings with a larger complement of smaller balls to support higher limiting speeds
  • Inner / outer rings available in standard SUJ2 bearing steel, ultra long-life SUJ7 steel or advanced heat-resistant SHX steel
  • Available with steel balls, ultra long-life EQTF steel balls or ceramic balls for higher seizure resistance and lower heat generation
  • High-performance polyamide, phenolic and engineered PPS resin cage design options available to meet specific application requirements
  • Non-contact sealed types available
  • Wide series and miniature series available
  • Available with 15º, 18º and 25º contact angles
  • With P2, P3, P3W, P4 and P4Y accuracy
  • For dimension series 19, 29, 10, 20 and 02
  • Available for bore diameters from 6 to 200 mm
  • For universal matching / arrangements

Operating Benefits

  • Ultra-high limiting speeds as much as 90% higher than conventional designs
  • Heat-resistant SHX steel rings and rollers deliver longer fatigue life (4 times) and support higher limiting speeds
  • Sealed designs prevent contamination and lubricant degradation, with grease life extended by as much as 50%
  • Dimensionally interchangeable with conventional bearing types
