Description

Technical Field

[0001] The utility model relates to the technical field of screw bearings, in particular to a long-life push-pull rotating screw bearing. Background Art

[0002] Push-pull and rotary screw bearings are primarily used in industrial equipment requiring high precision and reliability. These bearings typically utilize ball screw technology, which uses rolling elements to reduce friction and improve transmission efficiency and accuracy. For example, in equipment such as machine tools, electric injection molding machines, and automated production lines, these bearings provide stable and precise motion control.

[0003] Existing screws are usually installed on machine tools during use. However, during the processing of machine tools, a large amount of debris and other fine dust will inevitably be contaminated on the surface of the screw. When the screw continues to rotate, the dust will be transmitted to the inside of the bearing, which not only increases the friction between the screw and the bearing, but also causes the bearing to generate high temperature. Long-term high temperature and wear will not only affect the service life of the bearing, but also reduce its accuracy. Optimization and improvement are needed. Utility Model Content
