The hydraulic pump bearing is improved on the basis of oil bearing. The hydraulic bearing has more oil storage space than the oil-bearing, and has a unique loop-type oil supply circuit.

First of all, the hydraulic bearing improves the non-sealing design of the bottom of the traditional bearing and seals all the bottom of the bearing to form a sealed oil-retaining design. This effectively prevents the volatilization of lubricating grease and dust from entering the bearing. As a result, the service life of the bearing has been greatly extended.

Secondly, due to the unsealed design at the bottom of the traditional bearing, the lubricating oil cannot be stored too much. The hydraulic bearing uses the sealed bottom to design a large oil storage space, which can store a large amount of lubricating grease. This keeps the bearing lubricated at all times and greatly improves the stability of the hydraulic bearing.

In addition, the hydraulic bearing adopts special low wear and high temperature resistant grease. This grease has low wear rate and high temperature resistance. Even if the hydraulic bearing works continuously for a long time and is under high temperature, the grease in the hydraulic bearing will not volatilize, ensuring good lubrication for the bearing.

Not only that, the floating hydraulic bearing also uses the permeable oil circuit design, which makes the bearing and the oil storage tank interconnected, and facilitates the lubricating grease in the oil storage tank to enter the bearing smoothly. At the same time, it also uses powder metallurgy and special metals to make bearings. There are tiny holes in the bearing. Soak the bearing in special lubricating grease to make the hole full of grease.

During the operation of the hydraulic bearing, grease constantly overflows to lubricate the bearing. The bearing and oil storage tank are connected as a whole with the permeable oil circuit design, and the lubricating grease can flow freely, so as to achieve unrestricted self-lubrication.
