Product Overview: The HK 4520 Drawn Cup Needle Roller Bearing
The HK 4520 is a high-precision drawn cup needle roller bearing, featuring a bore diameter of 45mm, an outer diameter of 52mm, and a width of 20mm. As a key component in our Needle Roller Bearings category, this bearing is designed with a thin-walled, drawn outer cup that serves as a raceway for the needle rollers. This construction makes it exceptionally compact and lightweight, perfect for applications where radial space is limited but a high load-carrying capacity is required. Its open-end design allows a shaft to pass through the bearing.
The HK 4520 is typically press-fitted into the housing, which makes for a simple and economical installation without the need for snap rings or shoulders. It is an ideal solution for a wide array of industrial and automotive applications. Explore our full range of Drawn Cup Bearings to discover reliable components for your machinery.
