PRODUCT INFORMATION New Ultra-High-Speed Large Bearing for Motors in Hybrid Vehicles

Product Features A technological breakthrough enabling ultra-high-speeds Miniaturization of bearing width (Narrow width + offset groove) › Bearing width is minimized by offset and by maintaining cage strength and the guide surface of the cage. Long life technology / Dimensional stabilizing technology Reinforced PEEK cage › The use of carbon fiber reinforced plastic (PEEK) dramatically improves cage durability under ultra high-speed conditions. The use of dimensional stabilization technology and special heat treatment (HTF) controls age deterioration of the radial clearance and improves bearing...

Evaluation Results Test condition › Load: unloaded (only imbalance load due to rotational load) Rotation speed of outer ring: 10080 rpm › Rotation speed of inner ring: 4255 rpm › dmn 2.6 million equivalent (converted to cage orbital speed) › Lubricant: ATF 0.35 L/min @ 90 C › Test duration: 60 hours Test result Standard product Developed product Severe smearing on ball surface, inner and outer ring raceways, cage and wear Significantly increased sound pressure No abnormality Bearing sound pressure same as new product. Rough surface, wear Smearing, wear Skidding, wear No damage to cage and in...
