The IR 45x52x23 IS1 RICH inner ring, proudly manufactured by RICH in China, is a top-quality component designed to provide a hardened and precision-ground raceway for needle roller bearings. This expertly engineered inner ring ensures optimal performance and extends the lifespan of your bearing assembly, especially in applications where the shaft cannot be hardened and ground to serve as a raceway.
A key feature of this specific model is the one lubrication hole in the inner ring, which facilitates effective grease or oil distribution, enhancing the bearing's longevity and performance. With precise dimensions of a 45 mm bore diameter (d), a 52 mm outer diameter (D), and a 23 mm width (B), its robust construction makes it an ideal choice for various industrial and mechanical applications that require reliable support for rotating components and improved lubrication.
