KOYO bearing 30214 JR KOYO tapered roller bearing 30214

Tapered roller bearings belong to separate type bearings. Both inner and outer rings of bearings have tapered raceways. The bearing can be divided into single row, double row and four row tapered roller bearings according to the number of rollers installed. Single row tapered roller bearings can withstand radial load and unilateral axial load. When bearings are subjected to radial loads, there will be an axial component, so another bearing that can withstand the reverse axial force is needed to balance it.
