FAQ

What is the typical surface hardness of this IKO inner ring?

IKO inner rings are typically through-hardened to HRC 58 to 64, providing excellent wear resistance and durability for the raceway surface.

Yes, as long as the needle roller bearing is designed for a 40mm shaft diameter and is intended to be used with a separate inner ring, this IKO part can be used. It is manufactured to international standards, ensuring compatibility.

The inner ring should be press-fitted onto the shaft. It is crucial to apply even pressure to the end face of the ring using a proper mounting tool or sleeve. Never apply force through the outer diameter, as this can damage the precision-ground raceway.
