Regarding the interference fit between the shaft and bearing
Thread Content
In our facility, there is a shaft whose inner ring of the bearing was repaired by welding before it was machined. What should be the interference amount of the shaft during processing? The bearing model is SKF7311
7311 is a angular contact ball bearing; factors such as the angle, precision, and rotational speed need to be taken into account. It’s difficult to determine the appropriate preloading amount, so it’s best to consult the equipment manufacturer for guidance
For information on selecting bearings, you can contact Wuxi Xinzhuo Tai Transmission Equipment Co., Ltd. The website addresses are: http://www.xzt-nsk.com/ and http://www.nsk114.net – you can check these sites for details
The interference should be between 0.00 and 0.01, with a maximum of 0.015
