FAQ

The NKI series, like this NKI 25/20, includes a precision-ground inner ring (LRT252920). The NK series does not include an inner ring and is designed to run directly on a hardened and ground shaft. The NKI series is used when the shaft cannot be hardened to the required specifications.

This bearing is typically supplied with a rust-preventive coating and must be lubricated before or during installation. It is suitable for both grease and oil lubrication. The choice depends on the operating speed, load, and temperature of the application. Always refer to the machinery's service manual for specific lubricant recommendations.

Yes, the inner ring (LRT) and the outer ring with cage and roller assembly (TAF) for IKO needle roller bearings can often be sourced as separate components. However, for optimal performance and clearance, it is highly recommended to use them as a matched set as supplied from the factory, especially in precision applications.
