Timken Tapered Roller Bearing 63.5 mm ID, 110 mm OD, Steel Parallel Bore, Open End 390A/394A

The Timken 390A/394A Tapered Roller Bearing is engineered for high-performance rotary motion applications requiring robust load handling and precision. With an inside diameter of 63.5 mm and an outside diameter of 110 mm, this bearing features a parallel bore and a durable steel construction, ensuring reliable operation in industrial environments.

This bearing is part of Timken's TS (Tapered Single) series, consisting of two main separable components - the cone (inner ring) assembly and the cup (outer ring). The cone width of 18.82 mm provides solid support, contributing to its static load rating of 125 kN and dynamic load rating of 98.9 kN, which suit demanding mechanical assemblies.

The stamped steel cage securely retains the rollers on the cone, enhancing overall bearing longevity and performance. The open end design facilitates easy inspection, lubrication, and maintenance, reducing downtime in critical operations.

Applications are varied, including vehicle front wheels, differential and pinion configurations, conveyor rolls, machine tool spindles, and trailer wheel assemblies. This bearing fits both imperial and metric systems, making it versatile for international construction and repair standards.

Steel is used for both the rollers and the cage, providing high wear resistance and consistent rotational accuracy. The bearing is manufactured in the United States, reflecting stringent quality standards typical of Timken's industrial line.

Industrial use cases span manufacturing, automotive powertrain, material handling, construction equipment, and transport systems where rotary bearings must withstand both radial and axial loads.
