Cummins®

The Cummins 2869980 Needle Bearing is a specialized component designed for use in commercial trucks. It plays a significant role in the efficient operation of these vehicles by facilitating smooth movement and reducing friction between moving parts. Understanding its purpose and functionality is key to appreciating its importance in the maintenance and performance of commercial trucks.

Basic Concepts of Needle Bearings

Needle bearings are a type of rolling-element bearing that utilize elongated rollers, resembling needles, to support and reduce friction between moving parts. These bearings are constructed with an inner ring, outer ring, and a set of cylindrical rollers. The design allows for efficient load distribution and minimal friction, making them suitable for applications requiring high radial load capacity in compact spaces. Needle bearings operate on the principle of rolling-element bearings, where the rolling elements (in this case, the needle rollers) rotate between the inner and outer rings, significantly reducing friction compared to sliding contacts ¹.

Purpose of the 2869980 Needle Bearing in Truck Operation

The Cummins 2869980 Needle Bearing supports various components that experience high radial loads. It is typically found in applications where space is limited, yet the need for high load capacity is paramount. By facilitating smooth rotation and minimizing friction, this bearing contributes to the overall efficiency and performance of the truck, ensuring that components operate with reduced wear and enhanced longevity ².

Key Features of the 2869980 Needle Bearing
