The Timken Company LL205410-B Tapered Roller Bearing Cup

Description:

The Timken LL205410-B tapered roller bearing cup is a precision flanged cup (outer ring) designed for use with the matching Timken LL205449 tapered roller bearing cone (inner ring assembly) to form a complete TSF (Tapered Single with Flange) bearing set. The flanged cup design provides positive axial location within through-bored housings while supporting combined radial and axial loads with excellent alignment and durability. Commonly installed in industrial gearboxes, conveyors, mining equipment, construction machinery, agricultural equipment, and power transmission systems, this tapered roller bearing cup delivers dependable performance in demanding operating conditions. Maintenance teams, OEMs, and system integrators specify the Timken LL205410-B for equipment repair, replacement, machine rebuilds, and retrofits where a flanged outer ring is required for accurate bearing positioning and extended service life.

Applications:

The Timken LL205410-B tapered roller bearing cup is engineered for industrial applications requiring precise axial location and reliable support for combined radial and axial loads. It is widely used in industrial gear reducers, heavy-duty conveyors, mining and aggregate equipment, construction machinery, agricultural equipment, and power transmission systems where it operates with the Timken LL205449 cone to provide accurate shaft positioning, efficient load distribution, and long bearing service life.
