Product Description
Double Row Tapered Roller Bearings (Model: 30224/DF) 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 120mm, outer diameter of 215mm, and width of 80mm (total width 87mm), they offer a dynamic radial load capacity of 570kN and static radial load capacity of 890kN. 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 medium-duty industrial applications (e.g., machine tool spindles, gearboxes), 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.
