The CR 34398 Tapered Roller Bearing is engineered for rigorous industrial environments where a combination of high radial and heavy unidirectional axial loads must be managed simultaneously. Constructed from premium vacuum-degassed, high-carbon chromium steel, this single-row design features optimized raceway profiles and superior surface finishes that minimize friction, reduce operating temperatures, and extend service life significantly. With a dynamic load rating (Cr) of 120 kN, the 34398 is manufactured to precision tolerances (P6/ABEC-3 equivalent) ensuring consistent performance, exceptional reliability in high-speed applications, and accurate shaft guidance even under conditions of misalignment caused by mounting inaccuracies.
Designed as a critical component for large gearboxes, industrial pump drives, vehicle differentials, and high-load transmission systems, the CR 34398 offers unparalleled durability and performance consistency. Its separable design facilitates easier mounting and dismounting of the cone (inner ring assembly) and the cup (outer ring), simplifying maintenance routines and reducing costly downtime. Choosing the CR brand ensures access to world-class metallurgical standards and precision manufacturing, delivering a robust, cost-effective solution for minimizing operational risks and maximizing the uptime of your essential machinery.
