Timken 45280 Tapered Roller Bearing Cone

The Timken 45280 Cone is a tapered roller bearing cone designed for bearing assemblies that support combined radial and axial loads in industrial rotating equipment. It is used across gearboxes, conveyor systems, mining and aggregate machinery, agricultural equipment, construction machinery, and heavy‑duty trucks, delivering reliable load distribution and extended service life in demanding power‑transmission environments. This Single Cone (TS) bearing belongs to the 45200 Series and mounts with a Timken 45220 compatible cup in a press‑fit configuration, with tapered rollers engineered to carry both radial and axial loads while reducing friction. The cone’s construction uses high‑grade bearing steel and a pressed steel cage, and it is lubricated for operation with oil or grease. Key specifications include MPN 45280, Manufacturer Timken, Cone Part Number 45280, Load Type Combined Radial and Axial Loads, Mounting Type Press Fit, and Roller Type Tapered Rollers. Common replacements include Timken 45287 Cone, as well as SKF and NTN equivalents, reflecting its role in industrial rotating equipment, power transmission systems, and heavy machinery axles. This cone is designed to be used with compatible components in industrial and mobile equipment that demand robust load distribution, long service life, and predictable performance.
