The Timken Company 18790 Tapered Roller Bearing Cone

Description:

The Timken 18790 tapered roller bearing cone is used in single-row tapered roller bearing assemblies to support combined radial and axial loads while maintaining precise shaft alignment in industrial rotating equipment. Commonly installed in industrial gearboxes, conveyors, agricultural machinery, construction equipment, machine tools, and power transmission systems where dependable bearing performance is required. Maintenance teams, OEMs, and system integrators use this bearing cone for equipment repairs, machine rebuilds, preventative maintenance, and replacement of worn tapered roller bearing components.

Applications:

The Timken 18790 tapered roller bearing cone is commonly used in conveyor drive systems, industrial gearboxes, agricultural equipment, construction machinery, machine tools, and heavy-duty rotating equipment where high load capacity, accurate shaft positioning, and long service life are essential. It is typically paired with the Timken 18720 or Timken 18723 bearing cup to create a complete single-row tapered roller bearing assembly.
