Timken taper roller bearing cones are the inner race assembly of a taper roller bearing set — the component that mounts directly on the shaft and carries the rollers. Every Timken cone is precision-ground from premium bearing steel to exacting tolerances, ensuring consistent preload, smooth rotation, and maximum service life under combined radial and thrust loads.

Taper roller bearings are the industry standard for applications requiring high load capacity in a compact envelope. The tapered geometry allows a single bearing to handle both radial loads (perpendicular to the shaft) and axial thrust loads (along the shaft) simultaneously — something that straight roller bearings and ball bearings cannot match. This makes them essential in wheel hubs, gear drives, machine tool spindles, and rolling mill applications.

This product includes 45 cone variants grouped by bore size. Each cone is designed to pair with a specific Timken cup (outer race) — the matching cup number is listed in the specifications table. Always replace cones and cups as matched sets for optimal performance.
