Product Details
Thrust ball bearings from the seat , shaft ring and ball cage assembly of three parts . And the shaft with the axis of said ring, and the shell with said seat.
Thrust ball bearings can withstand axial load . Thrust ball bearings can withstand axial load. Thrust ball bearings , which ring with the shaft . Appear before the installation of seat spherical bearings, aligning performance , can reduce installation errors. Thrust ball bearings can bear radial load , lower speed limit.
Features:
With one-way , two-way two types.
2 In order to allow the installation error , whether it is one-way or two-way , you can choose spherical self-aligning spherical saddle -type or spherical seat type .
3 height grease technology - NSK grease lubricant technology can extend the life and improve bearing performance
4 high-grade steel ball - quiet and smooth high-speed rotation
5 Use the options in the ring, may allow the installation error .
Applies only to withstand side of the axial load, the speed on the lower parts , such as crane hooks , vertical pumps, vertical centrifuge , jack, speed reducer and so on. Shaft bearing ring , seat ring and rolling elements are separated, you can dismantle respectively .
Thrust ball bearing assembly has two key points . A cage and the ball is laminated quality control, the other is the nominal bearing after assembly height T control . In addition, since the shaft ring, seat ring can be separated , bring a management issues . Is to prevent the import of bearing parts mixed . M-type stamping cage assembly using crimping die . After pressing the ball in the pocket hole required rotation flexibility , but can not fall from the pockets and technical procedures check balls in the pocket bore runout . Solid cage stamping presses too small will make the ball runout and embossed with raised portions connecting the cage is too small and not strong enough , prone to block out phenomenon, resulting cage scrapped. Small thrust ball bearing race ring and the shaft diameter size difference is small , there is no obvious difference between the two sets of groups . In order to prevent the emergence of the phenomenon of mixed units , namely a set of bearings fitted into a set of difficulties are occurring Tao seat or are shaft washer situation. This need to take certain measures . Usually set when combined with auxiliary tooling would draw ring, seat regiment distinguished , or sampling nominal height diameter plug before checking with diameter size , in order to check the diameter of convenience, put the following races , placed above the shaft ring . If the diameter of a clear seat Court oxidized color quenching or without grinding , inner diameter of the test is not necessary , can obviously be seen that axis and the seat ring due to the difference , easy to mix sets. Thrust ball bearing assembly to be right after the nominal height T measurements confirm a hundred qualified. When measured with a high degree of alignment blocks or standard difficult pieces , and be measured load bearing rotation if need ten times , be sure to meet the minimum height . When the thrust ball bearing is operating at high speed , the ball and raceway contact angle of the radial plane will be affected by centrifugal force , thereby causing the ball slide relative to the raceway . This sliding adhesive wear caused by damage to bearings . To prevent such damage , must ensure that the minimum thrust ball bearings under load, as shown in Equation 1 or Equation 2 , whichever is the greater of the calculated value . .
Equation 1: Famin = K · n * n    Equation 2: Famin = Coa/1000   Famin: minimum axial load (N)
K: Minimum axial load factor     n: Speed ​​( per minute )    Coa: Basic static load rating (N)

Thrust ball bearings can only bear a load direction , if withstand the loads in both directions , you must use two-way thrust ball bearings. Thrust ball bearings must be applied minimum load or preload . When the axis perpendicular to the axis of weight usually exceeds the minimum load . At this time the opposite direction of the axial external load , which is possible to reduce the load acting .
