Angular Contact Ball Bearings
with SURSAVE Cage

New ultra-high speed Angular Contact Ball Bearings developed for the main spindle of machine tools: Low NRRO, low heat generation and high-speed performance.

The SURSAVE cage is applied to the NSKROBUST series of ultra-high speed angular contact bearings. 

Product Features

• Optimised internal design
• Lower vibration and runout of the cage reduce NRRO* by half
• 20% reduction of heat generation compared to conventional bearings under high-speed conditions
• 20% faster than conventional bearings

  *NRRO = non-repeatable runout

Benefits

• Higher accuracy
• Higher speed rotation
• Improve productivity
• Environmental friendly
• Reduction of NRRO improves the process surface quality and reduction of heat generation helps to suppress thermal desplacement
