GJP high precision tapered roller thrust bearing has the inner structure of tapered roller, which has a tapered roller spaced on each slot of bronze cage, and as it can bring a very compact axial bearing arrangement. Such bearings can withstand heavy axial loads, which are insensitive to impact loads, and have good rigidity. Because of it’s tapered roller structure, the rolling generatrix and the raceway generatrix of the washer meet at a certain point on the axis line of the bearing, so the rolling surface can get pure rolling and the limiting speed is higher than the thrust cylindrical roller bearing
