CR 21820 High-Capacity Tapered Roller Bearing | 101.6mm (4.0") Bore | Heavy Industrial Applications

The CR 21820 Tapered Roller Bearing is engineered for extreme durability and high load environments, offering superior performance in heavy industrial machinery. Utilizing high-purity, case-hardened bearing steel and precision-machined rollers, the 21820 is optimized to manage simultaneous radial and high axial loads with exceptional stiffness. Its geometrically optimized contact surfaces minimize friction torque and heat generation, ensuring stable operation even under continuous heavy cyclical stress. Designed to meet stringent ISO standards, this bearing provides exceptional dimensional stability and the tight tolerances required for complex gearbox assemblies and axle systems, reducing the risk of premature failure and costly downtime. Selecting the CR 21820 ensures a maximized service life and reduced operational costs for critical rotating equipment. Ideal for deployment in mining conveyors, heavy-duty gear reducers, pump drives, and agricultural machinery, this bearing is built to withstand contamination and shock loading. The CR manufacturing process incorporates advanced heat treatments and surface finishing, resulting in a robust component that maintains high accuracy over its lifespan. Invest in CR reliability to enhance the overall efficiency and longevity of your most demanding industrial applications.

Key Features

  • High Dynamic and Static Load Ratings (152kN Dynamic) for demanding applications.
