Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a self-lubricating rolling bearing. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Early linear motion bearings were a row of wooden poles placed under a row of pry plates. Modern linear motion bearings use the same working principle, but sometimes balls are used instead of rollers.

[0003] When common bearings are in use, a layer of grease is applied to the inside of the bearings to lubricate the balls so that they can slide smoothly. However, during use, the rotation of the balls will cause the grease inside the bearings to overflow, resulting in excessive consumption of grease and waste. Utility Model Content

Installing the buffer pads can protect the bearing outer ring and avoid damage to the bearing outer ring when installing the bearing outer ring.

[0011] Furthermore, the plurality of elastic clips are all made of metal and are treated with rust prevention. The rust prevention treatment of the elastic clips can prevent the bearings from rusting and losing their elastic force after long-term use, thereby increasing the service life of the elastic clips.

[0012] Furthermore, the plurality of slide rails are trapezoidal, and the plurality of retaining rings are matched with the slide rails close thereto. The slide rails are set to be trapezoidal so as to increase the limiting force on the clamping parts, so that the retaining rings can be in close contact with the outer ring of the bearing.
