In a humid environment, in a bi-directional thrust ball bearing will form condensate, which will cause bearing corrosion and shorten the service life of the bearing. Careful selection of grease can reduce the effect of condensation. The lubricating grease thickened with sodium soap has a strong absorption capacity for water and gas, but it oxidizes due to excessive moisture absorption and flows out of the bearing; Although soap and grease do not absorb water, appropriate additives can be added. It provides good corrosion resistance.
It bears some greases containing synthetic thickener can also provide excellent corrosion resistance and prolong the service life of the bearing. In the production of large bearings, the adjustment process systems such as formwork, formwork, test block and profiling are generally adopted; In single piece and small batch production, the scale on the machine tool or gauge block is usually used for adjustment. The content of adjustment also changes with the complexity of the artefact. For simple curved surfaces (such as inner and outer cylindrical surfaces), only the positional relationship of forming motion is generally adjusted; For the complex curved surface of ina bidirectional thrust ball bearing (such as spiral surface and involute surface), the speed relationship of forming motion is also generally adjusted.
Measurement error does not mean that the test tolerance can be relaxed by 10 percentages, but a certain degree of stability margin should be given to ensure that users can be accepted according to the standard. In the process of bearing parts machining, machine tools, fixtures and tools need to be adjusted in order to obtain the size, shape and position accuracy of bearing machining surfaces.
Any adjustment will inevitably lead to some errors. Check the bearing model, prepare the installation tool, check the bearing model, size meet the installation requirements. Depending on the structural characteristics of the bearings and supports, select the appropriate assembly method and be ready to install tools and gauges. Commonly used installation of INA two-way thrust ball bearing tools are hammers, copper rods, sleeves, special base plate, spiral mosquito pliers, presses, as well as cursor callipers, micrometres, per cent tables and so on.
If the bearing assembly and mating parts surface have bumps, rust layer, scraps, sand particles, dust and mud, on the one hand, bearing installation difficulties, resulting in incorrect assembly position; Therefore, before installation, the INA two-way thrust ball bearing shaft neck surface, housing holes, shaft shoulder end face, bushing, washers and end cap and other connecting components should be carefully examined. If there is a rust layer, it can be removed with a fine sickle and then polished with a fine sand cloth. At the same time, the surface of the bearing assembly and the accessories on its connections should be removed.
Thrust ball bearings introduce bearings as a combined structure, which is easy because seals, balls and cage assemblies can leave the unit. Two-way thrust ball bearings consist of a shaft ring, two bearing rings, two balls and support thrust components. Thrust ball bearings are a combination of bearings. The shaft ring, seat ring can be combined with the maintenance frame assembly, steel ball combination.
