Product Overview: The HK 0808 Drawn Cup Needle Roller Bearing
The HK 0808 is a compact and efficient needle roller bearing with key dimensions of an 8mm bore diameter, 12mm outer diameter, and 8mm width. As part of our Drawn Cup Bearings collection, it features a thin-walled, drawn outer cup that acts as a raceway for the needle rollers. This design makes it an excellent choice for applications requiring high radial load capacity within a minimal space. The cage-guided needle rollers ensure smooth, reliable operation at high speeds.
Ideal for installations where the housing bore can be used as the outer raceway, the HK 0808 offers a very compact and economical bearing arrangement. Its press-fit mounting simplifies assembly, eliminating the need for retaining shoulders or snap rings. Browse our full range of Needle Roller Bearings to find the perfect solution for your mechanical and industrial needs.
Key Features of the HK 0808 Bearing
