needle roller bearings

Needle roller bearings are used to help prevent stress on rollers. Designed small in diameter, these bearings can help extend bearing service life. Find durable needle bearings that can be used in engine components like rocker arm pivots, pumps, compressors, transmissions and more.Needle roller bearings are a type of roller bearing device that reduces friction between moving parts and supports radial loads. Needle roller bearings are characterized by the relatively long, thin rollers inside the bearing.

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.
