Product Overview: The IR 30*40*40 Inner Ring
The IR 30*40*40 is a precision-engineered inner ring, designed specifically for use with needle roller bearings. With a bore diameter of 30mm, an outer diameter of 40mm, and a width of 40mm, this component serves a crucial role in applications where the shaft cannot be hardened and ground to act as a direct raceway. Part of our specialized Inner Rings collection, it provides a hard, smooth, and dimensionally accurate surface for needle rollers to operate on, ensuring optimal performance and extending the life of the entire bearing assembly. As a key component within the Needle Roller Bearings category, the IR 30*40*40 allows for the use of these compact, high-capacity bearings in a wider range of machinery and equipment designs.
Key Features of the IR 30*40*40
- Precision Ground Raceway: The outer surface is expertly ground to tight tolerances, ensuring smooth, low-friction operation for the needle rollers.
- High-Quality Hardened Steel: Manufactured from through-hardened bearing steel for exceptional durability, wear resistance, and load-carrying capability.
- Standardized Dimensions: Conforms to industry standards (30x40x40mm), ensuring interchangeability and a perfect fit with compatible needle roller bearings.
- Chamfered Edges: Features smoothly chamfered edges to facilitate easy mounting onto shafts and prevent damage during installation.
- Enables Shaft Versatility: Allows for the use of needle roller bearings on softer, unhardened shafts, reducing the need for costly shaft treatments.
