Bearing rated load
Thread Content
Who knows how to calculate the rated load of bearings? Help please.
The bearings used in the crushers at our factory always burn out after a period of time in use. There are definitely no issues with the quality of the assembly or the bearings themselves; I suspect that the problem lies in the insufficient design capabilities for selecting the appropriate bearings. However, I don’t know how to calculate the load capacity of these bearings. Please help me analyze this issue.
As can be found in the design manual, the bearing capacity is listed in the bearing table.
Specifically, you need to convert your actual load into an equivalent dynamic load, and then compare it with the rated dynamic load of the bearing you intend to use. Calculation formulas are included in general mechanical design textbooks.
Go and search for a software version of the mechanical design manual; it contains calculation programs. Either check the manual and calculate it slowly by yourself.
The samples provided by bearing manufacturers are very detailed; you can simply look them up by model
