Deep Groove Ball Bearings Ball bearing, in which the rolling elements are spherical balls.The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. (Reducing the friction of certain moving parts by replacing sliding friction with rolling friction)With small friction and high-limit speed, cost-effective and require little maintenanceUsed in parts such as steering, engine, driveline, and driveshaft. Such as motors, skateboards, etc. Notice: Keep clean to prevent dust from entering the bearing.Do not make strong impact on the bearing during use.Use proper tools for mounting.Hot mounting is recommended for machinery and equipment with high precision requirements.When operating the bearings, pay attention to wearing gloves to prevent the bearings from corrosion and rusting.
