Needle roller bearings use long, thin cylindrical rollers to support radial loads. These needle rollers have a length that is typically three to four times its diameter. Needle roller bearings have a thinner cross section than other roller bearings and are ideal for limited-space.Needle roller bearings utilize small, cylindrical rollers, referred to as needle rollers, to reduce friction between moving components. The needle rollers are the load-carrying components of the needle roller bearing. They are located between two races, between a single race and a shaft.


Needle Roller Bearings Needle bearings feature a smaller cross-section, higher load-carrying capacity, greater rigidity, and lower inertia forces that facilitate size and weight reductions in machinery. They’re designed to withstand oscillation, perform under severe conditions, and interchange with sliding bearings.Metric shell type needle roller bearings have high length-to-diameter ratios. They are commonly used in farm and construction equipment, gasoline engines, gas pumps, and small appliances. Needle bearings have smaller rollers and the highest load capacity for a given radial space of all rolling bearings.
