Thrust roller bearings for axial load mainly axial , radial joint load , but the radial load should not exceed 55% of the axial load . Other thrust roller bearings, such bearings lower friction coefficient , high speed, and aligning performance . 29000 bearing stick asymmetric spherical roller , the roller can reduce the relative sliding and rolling in the work , and the roller length , large diameter roller quantity, high load capacity, usually oil lubrication , individual low speeds available greased . In the design selection , preference should be given ; 80000 Thrust cylindrical roller bearings , 90000 Thrust tapered roller bearings and needle roller thrust bearings AXK type , can withstand a one-way axial load , than the axial thrust ball bearings much greater load capacity and rigidity, axial occupy a small space. Thrust cylindrical roller bearings and thrust needle roller bearings for low speed applications , thrust tapered roller bearing speed slightly higher than the thrust cylindrical roller bearings. Thrust Roller Bearings Thrust into cylindrical roller bearings, spherical roller thrust bearings, thrust tapered roller bearings, thrust needle roller bearings Thrust cylindrical roller bearings are mainly used in oil rig, made ​​of iron steel machinery. Thrust Spherical roller Bearings these bearings are mainly used in hydroelectric power , vertical motors , marine propeller shafts , tower cranes , extruders , etc. thrust bearings tapered roller bearings such major purposes: one way : crane hook , turn oil rig ring bi : rolling mill roll neck thrust bearing assembly is mainly axial load , its wide application . Although the thrust bearing installation is relatively simple , but the actual repair is still often an error occurs, the tight and loose ring ring bearing mounting location that is incorrect , resulting in the loss of the role of the bearing , the journal will soon be worn. Retaining ring mounted on the end face of the stationary member , the mounting error . Tight inner ring and the journal of transition fit to drive when the shaft is rotated tight ring , and with the end surface of the stationary friction , subjected to an axial force (Fx) , it will appear larger than the inner diameter of the friction torque with the drag torque , resulting in tight ring and the shaft with face mandatory rotation , aggravated journal wear.
