Slewing Bearing good or bad identification methods and the purchase of slewing bearing considerations

Abstract: Slewing bearings are generally used in large equipment and equipment, can simultaneously carry axial and radial loads, is an important transmission components necessary for machinery. So how to identify the quality of slewing bearings? What are the precautions for buying slewing bearings? Here to understand.

First, the identification of slewing bearing quality good or bad method 1, slewing bearing surface quenching hardness can not be lower than 55HRC the following, the depth of hardened layer can not be lower than 4mm, the width of the soft zone can not be lower than 50mm, in the whole process of treatment should be formulated in accordance with the needs of customers.

2, slewing bearing grinding process is very important, need to choose the right grinding wheel to complete grinding, and the line speed will be strictly controlled, so as to avoid raceway burns. Then fine grinding, need to choose the granularity of 46 ° or 60 ° resin grinding wheel grinding, grinding amount can not exceed the rough grinding process, finish should meet the requirements of the specified level.

3, toughness is important. Slewing bearing is very thin (relatively), so a lot of times you can not just focus on looking good, but should be more consideration of the product's use of the environment and service life, we first choose, you can choose high-quality manufacturers, check the toughness of a good slewing bearing.

Second, the purchase of slewing bearing precautions when choosing slewing bearing should pay attention to three issues: load, bolt strength and bolt hole is uniform, these three conditions are essential. 1, bearing load distribution is reasonable, if the bearing is mounted on the lack of integrality of the support surface, the local deformation will change the load, resulting in the bearings have a different load size. If appropriate measures are not taken, it will easily lead to the failure of the slewing bearing.

2, the bolt is strong enough to ensure that you choose the right slewing bearing product for your installation. This stage is often overlooked, leading to the possibility of system failure. So this issue still needs extra attention. 3, bolt holes are even, because fasteners need to be placed in more than the maximum load area. Bolt holes should only be used as a hazardous support structure in areas where the maximum load occurs, so they should not be ignored in the overall design of the product. Uniform bolt collars help to minimize buckling and load distribution on bearings, fasteners and support structures.

Third, choose experienced manufacturers
