Product Overview: The HK 3020 Drawn Cup Needle Roller Bearing
The HK 3020 is a high-performance drawn cup needle roller bearing with open ends, featuring key dimensions of a 30mm bore diameter, 37mm outer diameter, and 20mm width. As part of our extensive range of Needle Roller Bearings, this component is designed for applications requiring high radial load capacity within a minimal space. Its unique construction involves a thin-walled, drawn outer cup that serves as a raceway for the needle rollers. This design makes it an exceptionally compact and lightweight solution, ideal for installations where the housing bore cannot be used as a raceway.
The HK 3020 is press-fitted into the housing, which provides a simple and secure mounting method. It is engineered to operate directly on a hardened and ground shaft. For applications where the shaft cannot be hardened, it can be used with a compatible inner ring. This bearing is a staple in various industries, offering reliable performance and high rotational precision.
