Product Description

This is the most basic and most widely used type of tapered roller bearing. It consists of two main separable parts: the cone (inner ring) assembly and the cup (outer ring). It is typically mounted in opposing pairs on a shaft. You can depend on NTN Tapered Roller Bearing Cone - 4T-JM511945 to outperform other bearings due to the durable steel design that lasts even in the most severe environments. These bearings feature precision tolerances, proprietary internal geometries, and quality materials.

NTN began in 1918 when investor Noboru Niwa brought his company Tomoe Trading Co. together with engineer Jiro Nishizono. Together, they pioneered and manufactured the first NTN ball bearings.
