The CR 40000 is a robust, single-row Tapered Roller Bearing engineered for severe industrial applications requiring extremely high combined radial and axial load capacity. Constructed from vacuum-degassed, high-carbon chromium steel (52100 equivalent), this bearing features optimized raceway geometry and superior roller conformity to minimize friction and heat generation under peak load. Its separable design, consisting of the cone (inner ring assembly) and the cup (outer ring), facilitates easier mounting and precise clearance adjustments in complex assemblies. The defined contact angle allows the 40000 series to effectively manage the large tilting moments and shock loads prevalent in heavy machinery, ensuring operational stability and predictable performance under continuous duty cycles.
Choosing the CR 40000 guarantees maximum uptime and extended service life for critical equipment such as heavy-duty gear reducers, mining conveyors, crane hooks, and industrial pump shafts. CR’s rigorous manufacturing processes ensure extremely tight tolerance management (P6 equivalent), resulting in lower operational vibration and reduced noise levels compared to standard commodity alternatives. This superior quality minimizes maintenance cycles and significantly reduces the Total Cost of Ownership (TCO) over the lifespan of the equipment, making the CR 40000 the optimal choice for demanding, reliability-critical operational environments.
