Overview
The SKF BR25877 is a single-row tapered roller bearing cone for inch-series applications requiring controlled preload and precise alignment. With a 1.375 in bore and 0.96875 in width, this cone is manufactured to standard precision tolerances for an exact fit. It is commonly specified for front outer axle shaft and rear wheel bearing locations, and is also used in certain transmission and drivetrain positions. Application coverage spans classic vehicles to modern commercial trucks, with documented use across platforms including Ford, Hino, International, Chevrolet, and Aston Martin.

Design and Materials
Constructed from heat-treated high carbon steel, the BR25877 combines strength and wear resistance under heavy radial and axial loads. SKF’s logarithmic roller–raceway profiles and ultra-smooth raceway finish help minimize edge stresses and vibration for smoother, quieter operation and stable contact patterns. Precision geometry supports consistent load distribution and helps maintain operating temperatures. As a cone component, BR25877 is installed with the correct mating cup specified by the application to achieve proper running clearance and service life. Manufactured to SKF quality standards with premium-grade steel, this cone provides reliable performance in demanding wheel-end and drivetrain service.

Service Notes
Use with the application-specified tapered roller bearing cup and follow OE torque/preload procedures. Inch dimensions ease specification and replacement across mixed fleets and legacy equipment. Where applicable, verify position (e.g., front outer or rear wheel) and seal compatibility during service planning.
