Product Overview: IR 40x45x40 Precision Inner Ring
The IR 40x45x40 is a high-precision inner ring designed for use with Needle Roller Bearings. With a bore diameter of 40mm, an outer diameter of 45mm, and a width of 40mm, this component serves as a hardened and ground raceway for needle roller and cage assemblies or drawn cup needle roller bearings. It is an essential part for applications where the shaft cannot be hardened and ground to the required specifications. By using an Inner Ring, you can ensure optimal bearing performance, reduced friction, and extended service life for your machinery.
Manufactured from high-carbon chromium bearing steel, the IR 40x45x40 inner ring offers exceptional hardness and wear resistance. It allows for the use of standard needle roller bearings on commercial-grade shafts, providing a cost-effective and reliable solution for a wide range of industrial and automotive applications. This component is crucial for achieving tight running accuracy and supporting high radial loads in compact spaces.
Key Features of the IR 40x45x40 Inner Ring
- Precision Ground Raceway: Provides a smooth, optimized surface for roller contact, minimizing friction and ensuring smooth rotation.
- High-Quality Material: Constructed from hardened, high-carbon chromium bearing steel for maximum durability and load-carrying capacity.
- Enables Use on Soft Shafts: Allows needle roller bearings to be mounted on shafts that are not hardened, saving on material and machining costs.
