1、 Are there any requirements for the appearance and location of the device?
yes. If foreign objects such as iron filings, burrs, and dust enter the bearing, it will cause noise and oscillation during operation, and even damage the raceway and rolling body. So, before installing the bearings, it is necessary to ensure the cleanliness of the device's exterior and environment.
2、 Is it necessary to clean the bearing device before installation?
The outer surface of the bearing is coated with anti rust oil. It is necessary to carefully clean it with clean gasoline or kerosene, and then apply clean, high-quality or high-speed, high-temperature smooth grease before the device can be used. The cleanliness has a significant impact on the lifespan and oscillation noise of bearings. But we would like to remind you that fully enclosed bearings do not require cleaning or oiling.
3、 How to choose smooth grease?
Smoothness has a crucial impact on the operation and lifespan of bearings. Here, we will briefly introduce the common criteria for selecting smooth grease. Smooth grease is made from base oil, thickeners, and additives. Different varieties and trademarks of smooth grease have significant differences in function, and the promised rotation limit varies. It is important to pay attention to this when selecting. The function of smooth grease is mainly determined by the base oil. Generally, low viscosity base oils are suitable for low temperature and high speed, while high viscosity base oils are suitable for high temperature and high load. Thickener is also related to smoothness function, and the water resistance of thickener determines the water resistance of smooth grease. In principle, different brands of smooth grease cannot be mixed, and even smooth grease with the same thickener can have negative effects on each other due to different additives.
