The IR35X40X30 is a hardened and ground inner ring designed for use with needle roller bearings that do not include an inner ring, such as those in the HK, NK, or NKI series. This component provides a precise and wear-resistant raceway surface, especially useful when the shaft cannot be ground or heat-treated.
Thanks to its extended length of 30 mm, the IR35X40X30 offers greater roller support, enhancing load distribution and operational durability, even in demanding industrial environments.
