FAQ

What does the ‘ADA-2LSV’ suffix mean for this NNF 5020 bearing?

The ‘ADA’ designation indicates that the bearing has a two-piece inner ring, which is held together by an internal retaining ring. This design facilitates easier mounting and dismounting. The ‘2LSV’ suffix means it has high-performance, low-friction contact seals made of NBR (nitrile rubber) on both sides, providing excellent protection against contamination and retaining grease, combined with a full complement roller set for maximum load capacity.

Can this bearing accommodate axial loads?

Yes, NNF series bearings like this one can accommodate axial loads in both directions. They are designed to act as locating bearings, meaning they can locate a shaft axially in both directions. However, their primary strength is in handling very high radial loads.

What type of lubrication is recommended for the NNF 5020 ADA-2LSV?

This bearing is typically supplied with a high-quality grease. The ‘2LSV’ seals are designed to retain this initial grease fill for a long service life under normal operating conditions. For relubrication or specific application requirements, it is essential to consult the SKF technical datasheet to ensure compatibility and use a suitable roller bearing grease.
