Double Rows Tapered Roller Bearings 3519/560

Double Row Tapered Roller Bearings (Model: 3519/560) are engineered for applications requiring high radial and axial load capacity in both directions. Constructed from premium-grade chrome steel (GCr15) with advanced heat treatment, these bearings deliver superior hardness and fatigue resistance. With a bore diameter of 560mm, outer diameter of 750mm, and width of 85mm (total width 213mm), they offer a dynamic radial load capacity of 3410kN and static radial load capacity of 8500kN. This double-row configuration provides exceptional radial and axial load capacity in both directions, with self-aligning capabilities to compensate for shaft deflection. The symmetrical design ensures uniform load distribution across both rows of rollers, enhancing stability and reducing wear under heavy or fluctuating loads. Suitable for heavy industrial machinery (e.g., mining equipment, rolling mills), these bearings are critical components in machine tool spindles, heavy-duty gearboxes, and large-scale industrial equipment. Equipped with a Standard cage, the bearing supports grease or oil lubrication and provides standard speed rating. Compliant with ISO 9001 and ABEC precision standards, it operates within a temperature range of -30°C to +120°C and requires precise preload adjustment during installation. The manufacturer offers a Standard 12-month warranty extendable up to 18 months through authorized Jinyu distributors. OEM solutions available.
