Deep Groove Ball Bearings
ZZ Shielded Deep Groove Ball Bearings
ZZ shielded bearings close the raceway with pressed steel shields, keeping dust out while letting the bearing run cool.
The metal shield sits close to the inner ring without touching it, so friction stays low and the bearing is suited to higher speeds. Grease is retained for the life of the bearing in most applications.
A common choice for motors, fans, pumps and household appliances where re-lubrication is not practical.
