Product Overview: The HK 1812 Drawn Cup Needle Roller Bearing
The HK 1812 is a compact and efficient drawn cup needle roller bearing with key dimensions of 18mm bore diameter, 24mm outer diameter, and 12mm width. As part of our extensive range of Needle Roller Bearings, this component is designed with a thin-walled, drawn outer cup that serves as the raceway for the needle rollers. Its low cross-sectional height makes it ideal for applications where radial space is limited but high load-carrying capacity is required. This bearing is an open-end type, making it suitable for through-shaft applications.
Manufactured to precise industry standards, the HK 1812 provides reliable performance in a variety of demanding environments. It is typically installed with a tight press fit into the housing, eliminating the need for shoulders or snap rings to locate it axially. For optimal performance, this bearing runs directly on a hardened and ground shaft. Explore our full catalog of Drawn Cup Bearings to find the perfect solution for your mechanical assembly needs.
