How to install ball bearings?
Install ball bearings are much easier than removing ball bearings. For smaller ball bearings, just use your fingers to push and make the the bearings seated. If you can’t get a bearing seated using the pressures from your fingers, you’re probably doing something wrong. If the bearing
Won’t slip in place, you may have the wrong size bearing or a small obstruction in the bearing bore. Plastic parts will sometimes “peel” along an edge as the bearing is pushed in, leaving a tiny plastic shaving that prevents a clean fit. If everything looks good and you still can’t get that sucker in there, press it against a flat surface such as your workbench. The most important part of a bearing installation is to make sure the bearing is fully and evenly seated. That is crucial.

 
Tips for Installing ball bearings:
1. The installation must be carried out in a dry and clean environment. Check the processing quality of each component before installation. All mating and connecting surfaces must be carefully cleaned and deburred, and uncast surfaces of castings must be cleaned of molding sand. 2. It should be cleaned with gasoline or kerosene before installation, used after drying, and ensure good lubrication. The bearings are generally greased or oiled.
2. During installation, equal pressure must be applied to the circumference of the end surface of the ferrule, and the ferrule must be pressed in. Do not directly strike with tools to avoid damage to the bearing.
3. In the case of small interference, press the end face of the bearing ring with a sleeve at normal temperature, tap the sleeve with a shank, and press the ring in evenly through the sleeve. If large-scale installation, hydraulic machine can be used. When pressing in, ensure that the end face of the outer ring and the shoulder face of the outer shell, the end face of the inner ring and the end face of the shaft shoulder are pressed tightly, and no gap is allowed.
4. When the interference is large, it can be installed by oil bath heating or sensor heating bearing method. The heating temperature range is 80 ℃ -100 ℃, and the maximum cannot exceed 120 ℃. At the same time, nuts or other suitable methods should be used to tighten the bearings to prevent the bearing from shrinking in the width direction and causing a gap between the ferrule and the shaft shoulder.
5. The rotation test should be carried out after installation. It is first used for rotating shafts or bearing boxes. If there is no abnormality, power is used for unloaded and low-speed operation, and then the rotation speed and load are gradually increased according to the operation, and noise, vibration and temperature are detected. If abnormality is found, the operation should be stopped and checked. It can be delivered for use only after the normal operation test. Through the understanding of the installation precautions of cylindrical roller bearings, although it seems simple, it is really not sloppy at all. I would rather understand these precautions before installation, rather than spend it in future use. A lot of time is spent on maintenance.
