Shielded deep groove ball bearings from SKF are flexible bearings that can handle high and extremely high speeds. In both directions, they can support radial and axial loads. Ball bearings are extremely low-maintenance. SKF deep groove ball bearings are available in a variety of sizes. Single row ball bearings are included in this category.

 

Shielded (2Z) bearings include two metallic dust shields to prevent dirt and extraneous debris from entering the bearing. 2Z bearings with two low-friction seals are known as 2RZ bearings.
