FAQ

For optimal performance and a proper interference fit, the recommended shaft tolerance is typically h5 or j5, depending on the load conditions and application. Always consult the IKO engineering catalog for specific recommendations.

Yes, this IKO inner ring is manufactured to standard ISO dimensions and can be used with needle roller bearings from other manufacturers (like INA, SKF, etc.) that require a 20x25x16 mm inner ring. However, for best results, it is recommended to pair it with an IKO needle roller bearing.

The inner ring itself is typically supplied with a corrosion-preventive oil. The complete bearing assembly (inner ring, cage, and rollers) must be lubricated according to the application's requirements, using an appropriate grease or oil before or during operation.
