Timken Tapered Roller Bearing 63.5 mm ID, 112.71 mm OD, Steel, Open End, 3982/3920

Timken 3982/3920 tapered roller bearing is engineered for mechanical, industrial, and fluid power applications that require precise, reliable operation under heavy loads. With an inside diameter of 63.5 mm and an outside diameter of 112.71 mm, this bearing is constructed with a steel cage and steel rollers, ensuring durability and consistent performance in demanding environments.

This tapered bearing features an open end design for straightforward maintenance, inspection, and lubrication. Its configuration consists of two main separable parts: a cone (inner ring) assembly and a cup (outer ring), which provide optimal load distribution along the shaft. The parallel bore type enhances accurate and secure fitting, making this bearing suitable for a wide range of mechanical assemblies.

Its static load rating of 191 kN and dynamic load rating of 139 kN offer robust performance, allowing for safe operation under varying loads and speeds. A cone width of 23.81 mm contributes to its structural integrity. The bearing supports both imperial and metric systems, facilitating global usability.

Timken’s 3982/3920 model is routinely used in vehicle front wheels, differentials, pinion configurations, conveyor rolls, machine tool spindles, and trailer wheel assemblies. Typical environments include manufacturing plants, automotive workshops, conveyor systems, and heavy machinery setups. Applications benefit from its high load capacity, efficient rotation, and long service life.

Steel cage construction retains rollers securely, and the open end design assists with rapid mechanical servicing. The bearing is designed for opposing pair installation, maximizing shaft efficiency and reducing wear. End users in industries such as automotive, industrial machinery, manufacturing, and logistics will find its performance suitable for high-demand rotary operations.
