[0002] In daily production, the common characteristics of bearing rubber seals include good sealing performance, low friction resistance, high wear resistance, self-lubricating performance, simple structure and easy installation. They can maintain stable sealing performance in different working environments and effectively prevent the leakage of gas, liquid and other media, but when the seal is too tight, it will increase the friction of the bearing, so it is necessary to select a suitable interference. In the process of selecting the interference, the seal and the bearing need to be removed or pulled off to determine the tightness of the seal by the size of the pull-off force, and then determine its appropriate interference, but there is currently a lack of suitable equipment to pull the seal and the bearing off and measure its pull-off force. This affects the normal use of the seal and the bearing and greatly reduces efficiency. Utility Model Content
