Description
This inner ring is a separate cylindrical component designed to be combined with a matching needle roller bearing, providing the inner raceway surface for the rolling elements. Bore diameter is 20.0 mm and width is 38.5 mm, with a net mass of 52.3 g. The cylindrical bore allows mounting directly on a shaft without additional adapter sleeves. As a standalone ring, IR20X25X38,5-XL is used when the shaft itself does not offer a suitable hardened running surface, letting the load-carrying track be replaced separately from the outer bearing components. Since it supplies only the inner raceway, sealing and lubrication depend on the full bearing assembly it is fitted into, and running accuracy is determined by the mating rolling element set selected for the application.
