One of the critical areas related to automobiles today is the conservation of natural resources. In a vehicle, only about 12.6 % of energy is used for moving the vehicle whereas 62% is lost to engine friction, engine-pumping losses and to waste heat, 17% is lost in idling, 2% lost in accessories operation and 5.6% lost in the drive train due to friction and slippage.
By understanding the various torque contributors to the bearing such as grease, seal and internal bearing geometry, NBC has developed the low torque bearing technology. The low torque grease has been developed by various fundamentals on tribo-meter along with design of low torque seal and optimization of internal geometry to improve fuel efficiency. Low torque bearings reduce friction by 15-20% and improve fuel efficiency.
NBC has engineered fuel efficient bearing for transmission and wheel bearing application of two wheeler segments. These bearings have also been developed for other automotive segments (cars, trucks, tractors, etc.) Various other programs are underway as well and NBC is working towards extending the technology to other areas.
