The superior features of this product, as detailed below, enable it to deliver ultra-high-speed rotation:
1. Carbon fiber reinforced PEEK (Polyaryletherketone) cage
To deal with the tremendous centrifugal force generated by the high-speed rotation of large-diameter bearings, carbon fiber reinforced PEEK is being used for the first time ever as a cage material for automotive bearings, dramatically improving cage durability.
2. Inner ring guide
The use of a crown cage for the ball guide along with the outer diameter of the inner ring as guide surfaces controls vibration and skidding damage resulting from cage runout, dramatically improving bearing durability during super high-speed rotation.
3. Optimized internal design and long life technology
Optimized radial clearance, ball diameter, number of balls, and groove dimensions inside the bearing module control friction and heat generation even under ultra-high-speed rotation, preventing seizure. In addition, the use of heat treatment technology and a material with superior dimensional stability on the inner and outer rings controls age deterioration of dimensions and radial clearance during usage, improving durability.
NSK low-torque and high-speed bearings for the specific use in hybrid and electric-vehicles are present in the latest HEV models such as Toyota Prius or Chevrolet Volt. By leveraging its four core technologies (tribology, materials, analysis, and mechatronics) developed over 90 years of experience, the company is continuing to create products that will improve fuel efficiency and comfort in the next generation vehicles.
