Ultra-High Speed Angular Contact Ball Bearings with SURSAVE Cage
NSK has developed ultra-high speed Angular Contact Ball Bearings using the new cage “SURSAVE" for the main spindle of machine tools.
This cage is applied to the NSKROBUST series of ultra-high speed angular contact bearings. Low NRRO, low heat generation and high-speed performance are achieved with the newly developed cage“SURSAVE”
Condition Description
- Green environment
- High Accuracy
- High Speed
Industries
- Machine Tools
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
