Product Overview: The HK 2020 Drawn Cup Needle Roller Bearing
The HK 2020 is a high-performance drawn cup needle roller bearing with an open-end design, featuring a 20mm bore diameter, 26mm outer diameter, and 20mm width. This bearing is engineered with a thin-walled, drawn steel outer cup and a cage assembly of needle rollers, providing exceptional radial load capacity within a very compact and lightweight design. Its unique construction makes it an ideal choice for applications where space is limited, but high load-bearing capability is essential.
As a key component in our Needle Roller Bearings collection, the HK 2020 is designed for a press-fit installation into the housing, eliminating the need for complex housing shoulders or snap rings. This simplifies assembly and reduces overall system cost. The open-end design is suitable for through-shaft applications and provides excellent guidance for the needle rollers, ensuring smooth and reliable operation in a wide range of industrial machinery.
