Compact Needle Roller Bearing for High Load Applications

Compact Needle Roller Bearing for High Load Applications

INA HK 0606 is a precision drawn cup needle roller bearing with open ends, designed for applications requiring high radial load capacity within extremely limited installation space. With dimensions of 6x10x6 mm, this compact bearing features a thin-walled outer ring and operates directly on a hardened and ground shaft, eliminating the need for a separate inner ring. Its lightweight construction and optimized rolling element design make it an excellent solution for gearboxes, power tools, pumps, precision drives, automation equipment and compact industrial machinery. Manufactured according to DIN 618 and ISO 3245 standards, HK0606 is widely used as an OEM component and a reliable replacement bearing in industrial maintenance.

Material Properties

The outer ring and needle rollers are manufactured from high-quality bearing steel to provide excellent wear resistance, fatigue strength and long service life. The pressed steel cage accurately guides the needle rollers while maintaining low friction during operation. Since HK 0606 operates directly on a hardened shaft, the shaft serves as the inner raceway, reducing component count and enabling highly compact mechanical designs. The typical operating temperature range is approximately -30 C to +140 C.
