How to choose the bearing model for a pump
Thread Content
There is a sewage feed pump with the model number EHG100--65--200A. Its bearings are damaged and need to be replaced; what model should be used? Are there any standards? How do I know what size to replace it with? I know absolutely nothing about this area; please, experts, give me some advice. Thank you, points will be given
The simplest and fastest way is to contact the pump manufacturer and provide the pump model. . . .
The outer ring of the bearing carries the corresponding bearing model; as bearing models are updated, old and new models differ from each other. Generally, when selecting a bearing, one should consider the bearing’s load-carrying capacity and the speed of the spindle, and it is possible to refer to mechanical design manuals or relevant bearing selection procedures for guidance.
You’ll know the bearing model after disassembly.
If the bearing is damaged, you can measure its inner and outer diameters as well as its width; then just search online for information based on the type of bearing
The simplest way is to remove the bearing; it has a model number on it (usually on the outer ring), such as 6308, 6212, and so on – these are all bearing model numbers.
