High Precision Chrome Steel Material Conveyor Roller Bearing 31308
Tapered roller bearings are separate bearings, bearing inner and outer ring with a tapered raceway. according to the number of columns,This type of bearing is divided into single row, double row and four row of tapered roller bearings and other different structural types. Single row tapered roller bearings are most popular ,which can withstand radial loads and single direction axial loads. When the bearing under radial load, will produce an axial component, so when you need another bearing in the direction of the axial force to balance.Tapered roller bearing type codes are 30200, 30300, 31300, 32000, 32200, 32300, 33200 and series inch types.
