Four Row Tapered Roller Bearings (Model: 382044/HC) are engineered for applications requiring maximum radial and axial load capacity in both directions. Constructed from premium-grade chrome steel (GCr15) with advanced heat treatment and precision grinding, these bearings deliver superior hardness, fatigue resistance, and dimensional stability. With a bore diameter of 220mm, outer diameter of 340mm, and width of 305mm (total width 305mm), they offer a dynamic radial load capacity of 2800kN and static radial load capacity of 5950kN. This four-row configuration provides exceptional radial and axial load capacity in both directions, making it ideal for applications with complex load profiles. The symmetrical design ensures uniform load distribution across all rows of rollers, minimizing stress concentrations and extending service life under extreme loads. Suitable for heavy industrial machinery (e.g., steel rolling mills, large gearboxes), these bearings are critical components in steel rolling mills, heavy mining equipment, and large-scale industrial machinery. Equipped with a Pressed steel cage, the bearing requires forced oil circulation with temperature monitoring to maintain optimal performance. It offers standard speed for heavy loads and operates within a temperature range of -20°C to +100°C. Compliant with ISO 9001 , installation requires meticulous alignment and preload adjustment. The manufacturer offers a Standard 12-month warranty extendable up to 18 months through authorized Jinyu distributors. OEM solutions available.
