SW IR 232820 High Precision Needle Roller Bearing Inner Ring | 140x165x20mm | Hardened Steel Race
The SW IR 232820 is a robust, high-precision inner ring designed specifically for use in combination with needle roller or drawn cup assemblies. Fabricated from through-hardened, high-carbon chromium steel, this race provides the necessary surface hardness and fine finish required to handle extreme radial loads and maintain operational integrity in high-speed applications. The precise dimensional tolerances ensure an optimal fit on the shaft, effectively eliminating fretting corrosion and extending the life of the entire bearing system. Unlike systems where the shaft serves as the running surface, using the IR 232820 allows for simplified replacement and maintenance, ensuring consistent performance characteristics.
Optimized for heavy industrial environments, the IR 232820 is crucial for applications requiring compact, high load-carrying bearing solutions, such as complex gearboxes, printing machinery, construction equipment, and heavy vehicle transmissions. Its standard dimensions allow for interchangeability with components from major manufacturers, providing flexibility in procurement and maintenance planning. Investing in this dedicated inner ring ensures peak system efficiency, minimizes downtime due to wear, and provides a reliable solution for demanding operational cycles where shaft resurfacing is impractical or cost-prohibitive. This component represents SW's commitment to quality, durability, and operational excellence in critical rotating machinery.
