[0002] Bearings can be divided into sliding bearings and rolling bearings. Among them, the common one is the rolling bearing, which usually consists of an inner ring, an outer ring, rolling elements and a cage. The inner ring rotates in cooperation with the shaft, and the outer ring plays a supporting role in cooperation with the bearing seat. In order to keep the bearing rotating smoothly, it is necessary to inject a grease agent between the rolling elements and the cage, so a grease injector for bearings is required.

[0003] However, during the use of the current bearing grease injection device, the grease injection outlet is exposed outdoors. After the equipment stops, due to the viscosity of the grease, it will stick to foreign impurities, which is likely to cause the problem of blockage at the outlet of the grease injection device.
