Application & Fit

The SKF BR45280 is a tapered roller bearing cone for axle assemblies in demanding, heavy-duty service. Key dimensions include a 1.750 in bore and 1.1875 in width, with a cone length of 1.2188 in and a cone radius of 0.0300 in. Intended for rear inner axle shaft locations, this component is sold as a single cone (bearing races/cups not included) to allow precise cup selection by application. The BR45280 aligns with VMRS code 053016002 and is compatible with select Ram axle models from 2019 to 2021, making it a dependable replacement choice for commercial and fleet maintenance programs.

Performance & Construction

SKF’s tapered roller design efficiently carries both radial and axial loads, maintaining bearing alignment under high loads typical of axle duty cycles. SKF incorporates logarithmic roller–raceway profiles and an ultra-smooth surface finish to promote smooth, quiet operation and consistent contact stress distribution. Manufactured to the company’s high quality standards, the BR45280 meets or exceeds requirements for most wheel bearing installations, supporting long service life in rigorous environments. For best results, install with the correct SKF cup (sold separately) specified for the axle, verify lubrication and preload settings per OEM procedures, and replace associated seals as required. This attention to fit and setup helps minimize downtime and ensures repeatable performance across fleet assets.
