Design Features
- Optimized internal design with larger sized rolling elements for increased load ratings
- J-type design option with long-life SHJ steel rings that deliver twice the fatigue life than standard SUJ2 bearing steel
- X-type design option with heat-resistant SHX steel rings that deliver 4 times longer fatigue life and 20% higher limiting speeds than standard SUJ2 bearing steel
- High-performance polyamide and phenolic resin cages support stable, ultra high-speed operation
- Silicon nitride (Si3N4) ceramic balls deliver outstanding speed and accuracy with low heat generation and high seizure resistance
- Non-contact sealed types available
- Optional oil-air lubrication features for a continuous supply of lubrication to the bearing working surfaces
- Available with 18º and 25º contact angles
- With P2, P3, P4 and P4Y accuracy
- For dimension series 10
- For universal matching / arrangements
Operating Benefits
- Higher machining capacity with maximum load capacity increased by 15% compared to NSKROBUST™ equivalents
- Longer spindle life with a 40% increase in dynamic load rating that extends bearing fatigue life as much as 3 times
- Higher impact resistance with higher static load ratings that reduce the risk of bearing damage
- Ultra high-speed performance with NSK’s proprietary heat- and seizure-resistant SHX steel achieving limiting speeds as great as 3 million dmN
