Drawn Cup Needle Roller Bearings

Needle roller bearings are a specialized class of cylindrical roller bearings characterized by their long, thin rolling elements, where the length-to-diameter ratio typically exceeds four-to-one. This unique geometry allows them to support high radial load capacities while maintaining an incredibly low profile, making them indispensable in applications with severe space or weight constraints. Available in several configurations—including drawn cup versions for economical, compact housing fits and solid machined rings for heavy-duty requirements—these bearings are commonly found in automotive transmissions, small engines, and precision power tools. By offering a larger contact surface area than standard ball bearings, they provide superior rigidity and efficiency, often running directly on a hardened shaft to further reduce the assembly's overall footprint and manufacturing complexity.
