The inner ring is used as the rollway of roller bearing. It is the common free gap when it is used in combination with needle roller bearing and has the changeability. Series IR inner ring is machined with precision machining after heat treatment. Series LR inner ring is ground after heat treatment. The chamfer in end face is not ground.
The common and high-precision inner rings can be produced in our company. All inch-system inner rings can be provided.
