Description

Technical Field

[0001] This utility model relates to the field of bearing end capping technology, specifically a bearing end capping device. Background Technology

[0002] Bearings are an important component in modern mechanical equipment, widely used in aerospace, machinery manufacturing, automobiles and many other fields. Their main function is to support rotating mechanical bodies, reduce the coefficient of friction during movement, and ensure rotational accuracy. To ensure that bearings can work properly in the equipment and transfer load from one part to another, they need to be correctly installed and fixed to prevent axial or radial displacement. However, existing bearing sealers do not have an automatic lubrication function and require manual replenishment of grease or oil periodically. Especially under harsh working conditions such as high load, high temperature, and high dust, the lubrication cycle may be shortened to once a day or once a shift. Manual operation is time-consuming and labor-intensive, increasing the company's labor costs. If lubrication is not done in time due to negligence or scheduling problems, the bearing sealer may heat up rapidly due to dry friction, causing surface wear, seizing, or even seizing.
