-The inner and outer ring raceways and rollers of these bearings are made with a taper so that the surface planes of the raceways and roller axis meet at a point.
-The rollers are guided by a flange on the inner ring.Tapered roller bearings are separable, and have the following components: outer ring,inner ring and roller assembly.
-The non-separable inner ring and roller assembly is called the 'cone', and the outer ring is called the 'cup'. Internal clearanceis established during mounting by the axial position of the cone relative to the cup.
deep groove ball bearing 6309zz mainly used in motorcycle rear axle wheel hub, heavy machine tools' main shafts, big power reduction gears, axletree axle boxes, roller wheels of transportation devices, and the supporting rollers and working rollers of the rolling mills.
