Low-Friction Tapered Roller Bearing with Plastic Cage Design for the Drivetrain Market

Product catalog summary

Development Background
The new low-friction tapered roller bearing (TRB) with a plastic cage has been developed to enhance performance and functionality. The design focuses on reducing agitation resistance and improving lubricating performance, while maintaining bearing strength using NSK proprietary materials that withstand harsh conditions.

Product Feature 1: Reduces Agitation Resistance
The new bearing design narrows the lubrication inlet and reduces the interior area, which minimizes surplus lubrication around the rollers. This is achieved through a cage design based on computational fluid dynamics, which contrasts with conventional steel cage designs that allow larger volumes of lubricant, increasing agitation resistance.

Product Feature 2: Improved Lubricating Performance
The new design includes an oil pool to ensure lubrication reaches the roller ends, preventing seizing due to excessive lubricant outflow. By regulating lubrication outflow to the sides, the new bearing ensures effective lubrication distribution, enhancing performance compared to conventional bearings.
