how it works:

thrust ball bearing is a separate type of bearings , shaft ring , seat ring and cage can , ball component separation. shaft ring is cooperating with the shaft collar , seat is compatible with the bearing hole ferrule , and there is a gap between the shaft ; thrust ball bearings can only bear axial load , one-way thrust ball bearings can only bear axial loads in one direction , two-way thrust ball bearings can withstand axial load in both directions ; thrust ball bearings can not limit the radial displacement of the shaft , low speed limits , one-way thrust ball bearings can limit a shaft and housing axial displacement direction , two-way bearing can limit the axial displacement in both directions .

thrust roller bearings for axial load mainly axial , radial joint load , but the radial load should not exceed 55% of the axial load . and other thrust roller bearings, such bearings lower friction coefficient , high speed, and aligning performance . 29000 -type non-stick bearing symmetrical spherical roller , the roller can reduce the relative sliding and raceways at 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 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 thrust cylindrical roller bearings.

application category:

thrust bearings thrust ball bearings and thrust into roller bearings .

thrust ball bearings and thrust ball bearings and thrust into angular contact ball bearings. raceway washer by the band and the ball and cage components and the shaft with raceway ring called shaft washer, and the shell with raceway ring called seat bidirectional bearing and the shaft will be in the ring with one-way bearings can withstand axial load , two-way bearings can withstand axial load . appear before the installation of seat spherical bearings with aligning properties, can reduce installation impact of errors. such bearings are mainly used in automobile steering mechanism , the machine spindle .

thrust into thrust cylindrical roller bearings roller bearings, spherical roller thrust bearings, thrust tapered roller bearings , thrust needle roller bearings.

thrust cylindrical roller bearings are mainly used in oil drilling rig, made of iron steel machinery.

axial spherical roller bearings these bearings are mainly used in hydroelectric power , vertical motors , marine propeller shaft , crane , extrusion machines.

tapered roller bearings thrust bearing these main purposes: one way : crane hooks , swivels oil rig bidirectional : rolling mill roll neck .

thrust bearing assembly mainly axial load , its wide application . although the thrust bearing installation operation 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 , the results of the bearing out of action , 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 for transition fit to drive when the shaft is rotated tight ring , and the end surface friction with the stationary element , the axial force in the subject (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.

thrust bearings
thrust bearings are generally made up of two or more thrust washers thrust washers and several rolling body composition, generally the most common type of
deep groove ball bearings
deep groove ball bearings are bearing the most common type . the basic model consists of a deep groove ball bearing outer ring, an inner ring, a set of balls
tapered roller bearings
tapered roller bearings are installed according to the number of rows of rollers into single row , double row and four row tapered roller bearings , such as d
