Zero class bearings are deep groove ball bearings. The original
name is single row radial ball bearing, is the most widely used It
is one of the most widely used rolling bearings. Its
characteristics are friction resistance, high speed, can be used to
bear radial load or radial and axial action at the same time. They
can be used to carry radial loads or combined radial and axial
loads at the same time. They can be used in machines subjected to
radial loads or combined radial and axial loads, as well as in
machines subjected to axial loads.
