Product Details
The IKO inner ring for shell type needle roller bearing is designed with a metric measurement of 25mm bore, 30mm outer diameter, and 15.5mm width, identified by part number IRT2515-1. These inner rings are heat-treated and finished by grinding to achieve optimal rigidity and precision. They are particularly useful when shafts cannot be hardened to a hardness range of HRC 58 to 64 and are unable to achieve a surface finish of 0.2 µm Ra or less.
