Application and Fit

The SKF JM207049 tapered roller bearing cone is built for demanding wheel-end and axle positions in heavy-duty on-highway and industrial equipment. Key dimensions—55 mm bore, 95 mm outer diameter, and 29 mm width—support OE-accurate fit in a range of hub and differential assemblies. With a basic dynamic load rating of 108 kN and a net weight of 0.569 kg, this cone is specified to carry significant radial and axial loads typical of commercial vehicle duty cycles. The JM207049 interchanges with major references, including Timken equivalents and select Volvo listings, helping fleets and rebuilders streamline sourcing and maintain standardization across mixed equipment.

Performance and Durability

Manufactured to SKF precision tolerances, the JM207049 helps maintain correct preload and contact geometry for consistent running temperatures and bearing life. SKF integrates a logarithmic roller–raceway profile with an ultra-smooth surface finish to minimize edge stress, reduce vibration, and promote quiet, stable operation. Designed for high-load environments, this cone delivers up to three times better wear resistance versus standard bearings, supporting longer service intervals and lower total maintenance cost. The cone length of 1.1417 in and 0.06 in cone radius further contribute to controlled contact zones under load, making the JM207049 a reliable choice for fleets targeting uptime and predictable wheel-end performance.
