In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a high-speed accurate disjunctor pottery deep groove ball bearing, includes bearing inner ring, spin and bearing outer loop, the second slot has been seted up to the centre of bearing inner ring outer wall, first slot has been seted up to the centre of bearing outer loop inner wall, the spin is installed between second slot and first slot, the oil groove has been seted up on the bearing outer loop of first slot inner wall one side, the oil duct has been seted up to bearing outer loop one side top.

Preferably, the bearing inner ring is located in the middle of the bearing outer ring, and the second groove corresponds to the first groove.

Preferably, the ball is matched with the second groove and the first groove respectively.

Preferably, the oil groove communicates with the first groove.

Preferably, the oil passage communicates with an oil groove.

Compared with the prior art, the utility model has the following beneficial effects: by arranging the oil duct and the oil groove, the utility model achieves the effect that the lubricating oil is added to the groove where the rolling ball works, and the rolling ball is fully contacted and lubricated with the lubricating oil. The utility model is provided with the oil duct and the oil groove, when lubricating oil is added, the lubricating oil injection pipe is inserted into the oil duct, and the operation of adding the lubricating oil is not influenced when the bearing inner ring rotates. During squeezing lubricating oil to the oil duct, lubricating oil enters into the oil groove along the oil duct, and lubricating oil flows along the oil groove, and lubricating oil and spin contact in the oil groove are along with the rotation of spin, and lubricating oil is taken to first slot and second slot inner wall on, makes spin fully contact lubricating oil.
