The HK 0808 is a drawn cup needle roller bearing (open end) designed to support high radial loads in very limited spaces. Thanks to its needle roller cage and compact design, it provides high load capacity and excellent load distribution, while maintaining low friction resistance.
It is especially suitable for low-speed rotating applications with tight installation requirements, such as power tools, gearboxes, transmissions, small motors, and portable mechanical devices.
