Deep Groove Ball Bearings FAG 6212 -2Z

The 6212-2Z deep-groove ball bearing from FAG Rolling Bearings combines a 60 mm bore with cover plates on both sides for effective dust protection and smooth running.

The single-row deep-groove ball bearing 6212 -2Z primarily absorbs radial forces and supports shafts with low friction. Manufactured from standard rolling-bearing steel 100Cr6, this bearing is characterised by the high dimensional stability of its raceways. Thanks to the sheet metal covers on both sides, the lubricant filling inside the bearing remains protected. This design provides a ready-to-install component for demanding rotational movements in industry and workshops.

What is the 6212 -2Z deep groove ball bearing suitable for?

This roller bearing is typically used in rotating shaft assemblies where moderate axial forces and predominantly radial loads are present. The design is suitable for industrial bearing arrangements operating at medium to high speeds. Thanks to its sealed construction, the bearing withstands moderate contamination in dry environments. Furthermore, the cylindrical outer ring without a groove facilitates installation in standard housing bores.

What are the advantages of the cover plates on the 6212-2Z deep groove ball bearing?

The suffix -2Z denotes two non-contacting cover plates made from profiled sheet steel. Unlike abiding seals, these plates do not generate any additional frictional resistance, making the bearing suitable for higher speeds with minimal heat generation. The shields mechanically screen out coarser particles and retain the factory-applied lubricant. When designing the system, it should be noted that shields primarily protect against solids, whilst they are not intended for direct exposure to liquids.
