FAQ

Question?
What is the difference between the TAF 556825 marked on the bearing and the NK 55/25 on the box?

The TAF 556825 designation typically refers to the complete bearing assembly, including an inner ring. The NK 55/25 designation refers to the outer ring and needle roller cage assembly without an inner ring. Both share the same external dimensions. This product consists of the outer assembly as indicated by the box.

Question?
Is an inner ring included with this bearing?

No, based on the distributor’s packaging (IKO NK 55/25 NAALDLAGER ZONDER BINN – meaning ‘without inner ring’), this product is supplied as the outer race with the needle and cage assembly only.

Question?
What kind of lubrication is required for this IKO needle roller bearing?

These bearings are typically lubricated with grease or oil. The specific type of lubricant and the relubrication interval depend on the operating conditions, such as speed, load, and temperature. Always consult the machinery’s maintenance manual for the correct lubrication specifications.
