Needle Roller Bearings are rotational motion bearings in which a thin needle-shaped roller is incorporated into a rolling element. They have a low cross-section height and high load capacity compared with ball bearings.
Characteristics
Radial compact structure, a smaller cross-section.
igher load-carrying capacity, greater rigidity.
Lower inertia forces that facilitate size and weight reductions in machinery.
Application
They’re designed to withstand oscillation, perform under severe conditions, and interchange with sliding bearings. Diverse types of needle bearings are available in a wide variety of sizes and tolerances, for a multitude of applications.
