Product Overview: The HK 0709 Drawn Cup Needle Roller Bearing
The HK 0709 is a high-precision drawn cup needle roller bearing with an open-end design, featuring a 7mm bore diameter, 11mm outer diameter, and 9mm width. This bearing is part of our extensive range of Needle Roller Bearings and is specifically categorized under Open End Drawn Cup Bearings. Its unique construction consists of a thin-walled, drawn outer cup that serves as a raceway for the needle rollers, which are securely held and guided by a cage. This design results in a very compact and lightweight bearing with high radial load-carrying capacity, making it an excellent choice for applications where space is limited but robust performance is required.
As a leading supplier of industrial components, we ensure our HK 0709 bearings are manufactured to precise industry standards. The press-fit installation into the housing makes it a simple and economical solution, as it eliminates the need for shoulders or snap rings to locate the bearing axially. This bearing is ideal for creating compact and cost-effective bearing arrangements in a wide variety of industrial and automotive machinery.
