At the same time, it is also used to drive auxiliary devices such as the distributor and gasoline pump. During the production process of the camshaft, the sealing ring needs to be pressed onto the end of the camshaft to meet the requirements of the camshaft sealing transmission. A good camshaft sealing ring press machine can not only meet the user's needs to quickly press the sealing ring onto the camshaft, but also have good protection functions to ensure that the camshaft will not be hard damaged during the pressing process.
