FAQ

What is the difference between IKO's NART and NATR series?

The primary difference is the roller guidance. NART series bearings, like this NART20UUR, have a cage that separates and guides the needle rollers for better performance at higher speeds. NATR series bearings are 'full complement', meaning they have the maximum possible number of rollers without a cage, which typically allows for higher load capacity at lower speeds.

The 'UUR' suffix on an IKO bearing indicates that it is equipped with double seals. Specifically, these are labyrinth seals, offering excellent protection against dust and contaminants from both sides of the bearing, while retaining grease effectively. This makes it suitable for use in environments with moderate contamination.

The IKO NART20UUR comes pre-greased with a high-quality lithium-soap based grease. For most applications, it is lubricated for life and does not require re-lubrication. If operating conditions are severe (high speeds, high temperatures, or heavy contamination), periodic re-lubrication may be necessary, following IKO's specific guidelines.
