IKO IR 32x40x24 Precision Inner Ring | Hardened Steel Raceway for Needle Roller Bearings

The IKO IR 32x40x24 Inner Ring is an essential component designed to complement caged needle roller assemblies where the shaft cannot be induction hardened or ground to serve as the raceway. Manufactured from high-quality alloy steel, this ring is precision ground and hardened to an optimum surface hardness (typically HRC 60-64), ensuring superior wear resistance and maximum dynamic load capacity. Its superfinished running surface minimizes friction, reduces operational heat generation, and ensures precise rotational accuracy, making it ideal for high-speed, demanding industrial applications such as gearboxes, power transmission systems, and heavy machinery. Selecting the genuine IKO inner ring guarantees seamless system compatibility and maximizes the service life of your entire bearing configuration. The standardized dimensions (32mm bore, 40mm outer diameter, 24mm width) allow for straightforward interchangeability and simplify maintenance procedures. By providing a dedicated, durable raceway, the IR 32x40x24 reduces overall system maintenance costs and minimizes unexpected downtime, delivering critical reliability in continuous operation environments. This component is engineered under strict IKO quality controls, offering the performance and longevity expected from a global leader in needle roller technology.
