The CR 400/455 Tapered Roller Bearing is engineered specifically for extreme heavy-duty industrial applications requiring superior rigidity and reliability under combined radial and axial loads. Constructed from high-carbon chromium steel (SAE 52100 equivalent) and featuring optimized raceway geometry, this bearing minimizes friction and heat generation, significantly extending operational life. The highly robust design, characteristic of the CR product line, ensures precise roller alignment even under significant misalignment or shock loading. With an open design suitable for advanced lubrication systems, the 400/455 bearing maintains peak performance in challenging environments such as mining conveyors, industrial gearboxes, and heavy vehicle axles.
As a Senior Product Manager, we emphasize that the initial investment in the CR 400/455 translates directly into minimized Total Cost of Ownership (TCO). Our commitment to stringent manufacturing tolerances guarantees predictable performance, reducing unplanned downtime and maintenance costs critical to major industrial operations. This unit's enhanced load-carrying capacity (C=1200 kN) combined with advanced surface finishing techniques ensures maximum durability and fatigue resistance. Choose the CR 400/455 for mission-critical installations where failure is not an option, leveraging CR’s reputation for industrial endurance and engineered longevity.
