BOWER IR 1820 OH Inner Ring 18x20x20mm | Precision Hardened Raceway for Needle Roller Bearings
The BOWER IR 1820 OH is a high-precision, separable inner ring designed for use with compatible radial needle roller and cage assemblies (e.g., K-series) where the shaft cannot be hardened and ground to serve as a raceway. Manufactured from high-carbon chromium bearing steel (SAE 52100), this inner ring is through-hardened and precision-ground to P6 tolerances, ensuring optimal running accuracy and maximum load distribution. The 'OH' designation signifies the inclusion of an oil hole for superior lubrication delivery directly to the rolling elements, critical for maximizing life in high-speed or heavy-duty applications, preventing premature wear and heat buildup.
Engineered for exceptional durability, the BOWER IR 1820 OH provides a cost-effective solution for creating a robust bearing arrangement. Its separable design simplifies mounting and dismounting processes, reducing downtime during maintenance. This component is ideal for demanding industrial environments, including transmissions, power tools, agricultural machinery, and automotive gearboxes. Trust BOWER quality for components that ensure long service life and reliable performance under continuous heavy radial loads.
