Drawn cup needle roller bearings

Drawn cup needle roller bearings are compact radial bearings featuring thin-walled, drawn steel outer rings and small-diameter cylindrical rollers. Their thin cross-section makes them ideal for applications with limited radial space while still providing high load capacity. Available in open, sealed, and caged designs, they accommodate radial loads and moderate speeds in constrained envelope conditions.

When selecting drawn cup needle roller bearings, the designation typically indicates bore diameter (e.g., HK1614 = 16mm bore), outer diameter, and width. Caged versions (suffix B) offer better roller guidance and higher speeds, while sealed variants (.RS, .2RS) provide protection in contaminated environments. Common applications include automotive transmissions, power tools, small electric motors, and printing machinery where space savings are critical.
