All of the internal rings have been heat treated and fine machined .If the shaft cannot be heat treated, it is better to use the internal ring as a sleeve. If the needle bearing and internal ring is used at the same time, the play is a common one and they are interchangeable. Our Company also produces the internal ring with accurate play and produces various internal rings with metric and British systems.
