Bearings are unfamiliar to most of us, but we often come into contact with them in our daily life, but we just don't know much about them. For example, there will be bearings on children's toy cars, refrigerators and air conditioning engines. Our commonly used bearing types mainly include deep groove ball bearings, angular contact ball bearings, self-aligning roller bearings and thrust self-aligning roller bearings, There are six kinds of cylindrical roller bearings and thrust self-aligning roller bearings. In order to correctly install and use the bearings, China bearing network shares the following installation matters according to experience.

 Installation of deep groove ball bearing

Deep groove ball bearing

1. When installing the bearing, the stress shall be uniform and direct hammering is not allowed. For example, if the fit interference is large, the bearing shall be heated in an air heating furnace or oil furnace with automatic temperature control, and the heating temperature shall be strictly controlled below 120 °.

2. The bearing equipped with nylon cage can work continuously and stably for a long time at - 40 ° - 120 °, the working time at 150 ° shall not exceed 4 hours, and the transient temperature peak shall not exceed 180 °.

3. The warehouse for storing bearings shall be clean and dry, and shall not be stored in the same warehouse as chemical products. The relative humidity shall not exceed 65%, and the bearings shall not be stored on the ground.

4. The bearings in stock shall be cleaned again every other year and packaged for rust prevention.
