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. Can this inner ring be used with any brand of needle roller bearing?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. What is the correct installation procedure for this inner ring?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. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
