Large plane thrust ball Bearing 51272 51292 512/500
Thrust ball bearings are designed to withstand thrust loads during high-speed operation, and are composed of washer-shaped ferrules with ball rolling grooves. Because the ring is in the shape of a cushion, thrust ball bearings are divided into two types: flat base cushion type and self-aligning spherical cushion type. In addition, this kind of bearing can bear axial load, but cannot bear radial load.
There are two key points in the assembly of thrust ball bearings. One is the control of the pressing quality of the cage and the steel ball, and the other is the control of the nominal height T after the bearing is assembled. In addition, since the shaft ring and seat ring can be separated, a management problem arises. It is to prevent the mixing of imported bearing parts. M-type stamping cage uses flange assembly die. After pressing, the steel ball is required to rotate flexibly in the pocket, but it cannot fall off from the pocket, and the movement amount of the steel ball in the pocket should be checked by technical regulations. If the solid cage is embossed too deeply, the steel ball will move less, and the connection between the embossed protruding part and the cage is too small and the strength is insufficient, which is prone to blockage, causing the cage to be scrapped. There is very little difference between the inner diameter of the small thrust ball bearing race and the shaft ring, and there is no obvious difference between the two sets. In order to prevent the phenomenon of mixed sleeves, the installed set of bearings will be trapped in the seat ring or the shaft ring. This requires certain measures. Usually, auxiliary tooling is used to distinguish the ring and seat ring when fitting, or the inner diameter plug gauge is used to check the inner diameter size before the nominal height is sampled. For the convenience of checking the inner diameter, put the seat ring underneath and the shaft ring on top. If the inner diameter of the seat cabinet has obvious quenching heating oxidation color or has not been ground, there is no need to inspect the inner diameter size. It can be clearly seen that the shaft is different from the seat ring and is not easy to mix. After the thrust ball bearing is assembled, the nominal height T needs to be measured to confirm that it is 100% qualified. When measuring, use a height block or standard part to calibrate and measure the load. The bearing needs to rotate dozens of times, and the minimum height must be reached.

FAQ1: What are the main uses of large thrust ball bearings?
Large thrust ball bearings are mainly used in heavy machines like presses, cranes, marine shafts, and gearboxes. They support high axial loads and ensure smooth rotation under heavy pressure.
FAQ2: What lubrication is best for large plane thrust bearings?
High-quality lithium or calcium-based grease is commonly used. For very high-speed or hot environments, circulating oil lubrication provides better cooling and performance.
FAQ3: How do thrust ball bearings handle axial loads?
They are designed with balls positioned between two washers. When force pushes along the shaft axis, the balls transmit the load smoothly while allowing rotation with minimal friction.
FAQ4: Maintenance tips for large thrust ball bearings in presses?
Keep the bearing clean, use proper lubrication, and avoid overloading. Regularly inspect for wear or noise, and ensure correct alignment to extend bearing life and prevent failure.
