FAG Needle Roller Bearings Guide

Product Description

The HK1512 FAG drawn cup needle roller bearing consists of a thin-walled drawn outer cup, needle rollers, and a cage, without a separate inner ring. Its open-end HK design allows the shaft to pass through the bearing, while the shaft surface can serve directly as the inner raceway. Therefore, the bearing achieves a very small radial cross-section with high radial load capacity. The cage guides and separates the needle rollers, helping reduce friction and supporting good speed capability.

The HK1512 bearing is suitable for automotive, precision machinery, industrial transmissions, power tools, small electric drives, and general mechanical engineering. Its compact radial dimensions make it particularly suitable where installation space and component weight are limited. Meanwhile, the open-end structure works well with through-shaft arrangements, while its high radial load density and compact construction support efficient operation in small mechanical systems.
