Do I need to ensure the mounting area is clean and free of contaminants before installing a deep groove ball bearing?

Firstly, a clean and pollution-free installation area is crucial for the normal operation of deep groove ball bearings. If there are pollutants such as dust, sand, and metal debris in the installation area, these impurities can easily enter the interior of the bearing during the installation process. Once they enter the bearing, they will constantly rub and collide between the rolling elements (steel balls), raceway, and cage of the bearing, cause to increased wear of the bearing. This not only reduces the service life of the bearings, but may also cause noise, vibration, and even jamming during operation, affecting the normal operation of the entire mechanical equipment.
Secondly, a clean installation area helps ensure the accuracy of bearing installation. Deep groove ball bearings typically require precise installation on the shaft and bearing seat to ensure their normal working clearance and rotational accuracy. If there are pollutants in the installation area, it may affect the installation position and angle of the bearings, resulting in inaccurate installation. This will cause uneven loads on the bearings during operation, further accelerating bearing damage.
In addition, a pollution-free installation environment can also avoid chemical corrosion of bearings. Some pollutants may contain corrosive components such as acids, alkalis, etc., which can react chemically with bearing materials, damaging the surface quality and structural strength of bearings.
