The IR45X55X20 RICH is a precision-engineered inner ring for needle roller bearings. This component is essential for creating a complete bearing assembly when the shaft cannot be hardened and ground to serve as the raceway. Made from high-quality, hardened bearing steel, its surface is precision-ground to provide a smooth and durable rolling surface for the needle rollers. The use of a separate inner ring facilitates easier mounting and dismounting of the bearing assembly, making it a versatile and reliable choice for various applications.
