1、 The use and installation shall be careful, and strong stamping is not allowed. The solution to the bad phenomenon of ina combined needle roller bearing is not allowed to directly knock the bearing with a hammer, and the pressure is not allowed to be transmitted through the rolling body.Needle Roller Bearing Clearance Change Failure Maintenance Technology
2、 Use proper and accurate installation tools, try to use special tools, and try to avoid using cloth and short fiber.Needle Roller Bearing Clearance Change Failure Maintenance Technology
3、 Keep ina combined needle roller bearing and its surrounding environment as clean as possible. Sodium base grease is generally used for motor bearing. Even if the invisible smile dust enters the bearing, it will increase the wear, vibration and noise of the bearing.
