Deep Groove Ball Bearings - Series: 618 

Ranges: inner rings: 100mm-950mm; outer rings: 125mm-1150mm


The Deep Groove Ball Bearing is one of the most representative rolling bearings. A simple structure and convenient usage characterize it. This type of bearings is widely used to bear radial load. This bearing can behave as “Angular Contact Ball Bearing” when the radial clearance increases to simultaneously support the axial and radial loads. Under the situation when the rotational speed is high and the thrust ball bearing is not recommended,  the Deep Groove Ball Bearing can be adopted to support the axial load. 

Deep Groove Ball Bearing has a lower frictional coefficient and a higher rotational speed limit than the other bearings. However, it lacks impact resistance and is inappropriate to support a heavy load.  


It applies to precision, low-noise electric, automobiles, motorcycles, etc.
