Product Overview: The HK 0908 Drawn Cup Needle Roller Bearing
The HK 0908 is a compact and efficient needle roller bearing, featuring a bore diameter of 9mm, an outer diameter of 13mm, and a width of 8mm. As a type of Drawn Cup Bearing, it consists of a thin-walled, drawn outer cup and a needle roller and cage assembly. This design creates a highly compact and lightweight bearing with exceptional load-carrying capacity for its size. The outer cup also serves as the raceway for the rollers, making it an economical choice for a wide range of applications.
Ideal for designs where radial space is limited, the HK 0908 is installed with a tight press fit into the housing, eliminating the need for shoulders or snap rings. This simplifies housing design and reduces machining costs. Part of our comprehensive Needle Roller Bearings collection, this component provides a reliable and rigid bearing arrangement, perfect for industrial machinery, automotive systems, and power tools.
