If foreign matter such as iron filings, burrs, dust, etc. enters the bearing, it will cause noise and vibration during the operation of the bearing, and even damage the raceway and rolling elements. Therefore, before installing the bearings, you must ensure that the mounting surface and the installation environment are clean.
Bearings must be cleaned before installation. The bearing surface is coated with anti-rust oil. You must clean it with clean gasoline or kerosene, and then apply clean or high-speed high-temperature grease to install. The effect of cleanliness on bearing life and vibration noise is very large. But we must remind you that the fully enclosed bearings do not need to be cleaned and refueled.
How to install and disassemble the installation without directly hammering the bearing end face and the non-stress surface, the bearing should be evenly stressed by the clamp, sleeve or other installation tools. If the mounting surface is coated with oil, it will make the installation smoother. If the interference is large, the bearing should be placed in mineral oil and heated to 90--100 °C and installed immediately. When disassembling is difficult, it is recommended that you use the disassembly tool to pull outward while carefully pouring hot oil onto the inner ring. The heat will cause the inner ring of the bearing to expand, making it easier to fall off. www.chamferingmachinechina.com
