Application and Fitment

The SKF BR39580 is a tapered roller bearing cone for heavy-duty truck wheel ends. Precision dimensions—57.15 mm cone inner diameter, 1.1875 in cone length, and 0.14 in cone radius—support correct seating and stable preload in non-driven front or rear positions. Used in pairs with a matching cup (sold separately), the cone forms a complete tapered roller bearing set for proper load sharing. Typical applications include Volvo heavy-duty models such as F616, F7, F8G, and N10, along with other wheel-end configurations that specify these dimensions. At 1.06 kg, the BR39580 offers a robust, service-ready component that integrates cleanly into standard fleet maintenance practices.

Design and Performance

The BR39580 incorporates SKF’s tapered roller bearing technology with logarithmic roller raceway profiles and an ultra-smooth surface finish to promote smooth, quiet operation under demanding conditions. The controlled cone geometry supports even load distribution across the roller complement, reducing edge stresses that can accelerate wear. Dimensional consistency enables reliable setup and repeatable torque/preload during service, helping fleets maintain uptime. When paired with its corresponding cup, the contact pattern is optimized for combined radial and axial loads typical of wheel ends, providing predictable performance and supporting long service life. Manufactured to SKF quality standards, this cone is engineered for durability in demanding operating environments without compromising installation efficiency.
