The NTN Inner Ring is a precision-engineered component used in needle roller bearing assemblies. The ring features a finely finished raceway and flattened end faces to ensure smooth operation and reduced friction. Designed without lubrication holes, it’s ideal for applications where external lubrication is managed separately.

Manufactured to ISO Class 0 (RBEC 1) tolerance for consistent performance

Made from high-carbon chrome steel for durability and wear resistance
