CR 43072 High-Performance Tapered Roller Bearing | Heavy Industrial Load | 35x80x31mm

The CR 43072 is engineered for extreme durability in demanding industrial environments, functioning as a premium single-row Tapered Roller Bearing (TRB) unit. Constructed from case-carburized alloy steel, this bearing provides superior rigidity and outstanding resistance to shock loads and fatigue. Its optimized geometry ensures excellent alignment and distribution of both high radial and axial forces, critical for stabilizing rotating machinery components under constant stress. The precision-matched cone and cup assembly minimize friction and heat generation, resulting in reliable operation even at elevated operating temperatures and limiting speeds up to 5,600 rpm. Designed specifically for heavy-duty applications such as gearboxes, mill stands, construction equipment transmissions, and large pump systems, the CR 43072 guarantees extended service intervals and reduced total cost of ownership. The robust design, combined with CR's commitment to quality control, ensures exceptional life expectancy and predictable performance, reducing unplanned downtime. Choose the CR 43072 for mission-critical installations where failure is not an option, leveraging its high dynamic load capacity (58.5 kN) to maintain productivity and system integrity.
