FAQ

Question?
What does the 'NR' suffix in 211.NR.Z signify?

The 'NR' suffix indicates that the bearing has a snap ring groove machined into the outer ring and is supplied with a corresponding snap ring. This feature allows the bearing to be located axially in a housing bore with a simple snap ring, saving space and simplifying the design.

Question?
What is the purpose of the 'Z' suffix?

The 'Z' suffix denotes that the bearing is equipped with a pressed metal shield on one side. This shield helps to retain lubricant and protect the bearing's interior from larger contaminants, while the other side remains open, typically for lubrication purposes or integration into a sealed assembly.

Question?
Can this bearing be used in a high-speed application?

Yes, deep groove ball bearings are suitable for high-speed operation. However, the limiting speed depends on factors like lubrication, load, and heat dissipation. The 'Z' shield has low friction and is well-suited for high speeds, but always consult the manufacturer's datasheet for specific speed ratings based on your application's conditions.
