This inner ring is designed as a separate cylindrical component that runs together with the matching needle roller and cage assembly or full complement needle roller bearing, forming a complete bearing arrangement with a bore diameter of 20.0 mm and a width of 26.5 mm. The net mass of the ring is 35.9 g, and its cylindrical form allows a hardened, precisely ground inner raceway surface for the rolling elements. Using the separate inner ring IR20X25X26,5-XL allows the shaft seat to be matched independently of the outer bearing components, which simplifies mounting and replacement when only the inner raceway requires renewal. As a bare ring without integrated sealing or lubrication, it must be paired with the corresponding roller and cage set and lubricated according to the requirements of the complete bearing arrangement in which it is installed.
