The FR6 series features a wide support cross-section, offering excellent rigidity among inch-series bearings. The flanged design not only addresses axial displacement issues but also increases the contact area between the bearing and the mounting base, thereby improving stress distribution. In applications such as automatic door control systems or heavy-duty manual controls, it delivers a solid tactile feel and precise motion tracking.
Bearing Features
Manufactured from high-quality bearing steel, models like the FR1038 exhibit exceptional dimensional consistency—a critical factor for ensuring synchronized performance across pivot points in multi-axis linkage systems. With a hard outer layer and a tough core, these bearings effectively resist micro-crack propagation caused by cyclic stress, ensuring outstanding reliability.
