Hydraulic bearings differ significantly from conventional bearings in a number of ways. The following is a detailed analysis of the comparison between the two:

First, the structure and design

Hydraulic bearings: improved on the basis of oil bearing, with a larger oil storage space and a unique loop-back oil supply circuit. It adopts a closed oil retention design, effectively preventing the volatilisation of lubricating grease and dust from entering the bearing. In addition, the hydraulic bearing also uses a pressure-permeable oil circuit design, which makes the bearing and the oil reservoir intercommunicate, and the lubricating grease can flow freely, so as to realise unrestricted self-overflow lubrication.

Conventional bearings: Usually have a simpler structure and do not have the complex oil circuit and reservoir system of hydraulic bearings. Its lubrication method may be more single, and it is difficult to ensure that in a long time operation to maintain a stable lubrication state.

Second, the performance characteristics

Bearing capacity:

Hydraulic bearings, due to the use of hydraulic principles, have a high load-bearing capacity, can be applied to high load working environment.

Traditional bearings have a relatively limited load-bearing capacity, especially in high load and high-speed operating conditions, its performance may be greatly affected.

Service life:

Hydraulic bearings typically have a longer service life because their unique lubrication system and oil reservoir design ensure that the bearings remain well lubricated over a long period of time, reducing wear and failure.

Conventional bearings have a relatively short service life, especially in harsh operating environments where wear and failure rates may be higher.

Noise and vibration:

Hydraulic bearings operate with relatively little noise because their lubrication system reduces friction and vibration.

Conventional bearings may produce greater noise and vibration at high speeds, affecting the overall performance and comfort of the equipment.

Maintenance costs:

Hydraulic bearings, while having a higher initial investment, may have lower maintenance costs in the long run due to their long life and low failure rate.

Traditional bearings may have relatively high maintenance costs due to the need for frequent replacement and repair.

III. Scope of application

Hydraulic bearings: they are suitable for occasions with very high performance requirements, such as high-speed rotating equipment, precision machine tools, aerospace and other fields. Its high load carrying capacity, long life and low noise characteristics make hydraulic bearings have significant advantages in these fields.

Due to their unique performance advantages, hydraulic bearings have a wide range of applications in many fields. The following is a summary of the main application scenarios of hydraulic bearings:

3.1. Engineering machinery field

In the field of construction machinery, such as excavators, loaders and other heavy equipment, hydraulic bearings also play an important role. These equipments usually need to withstand high loads and harsh working environments, and the high load carrying capacity and stability of hydraulic bearings can meet these needs. Its unique hydraulic principle allows the bearing to maintain a stable lubrication state during operation, reducing wear and failure, and improving the reliability and service life of the equipment.

3.2 Industrial field

In the industrial field, such as textile machinery, printing machinery and other equipment requiring high precision and high stability, hydraulic bearings also have a wide range of applications. These equipments require high precision and reliability of bearings, and hydraulic bearings can meet these requirements through its high precision processing and unique lubrication system to ensure the stable operation and processing precision of the equipment.

3.3 Automobile manufacturing field

In the field of automobile manufacturing, hydraulic bearings also play an important role. For example, in transmissions, clutches and other key components, the high bearing capacity and low noise characteristics of hydraulic bearings can ensure the stability and comfort of the automotive transmission system. At the same time, hydraulic bearings are also able to maintain stable performance in high temperature and high-speed operating environment, improve the overall performance and service life of the car.

3.4 Other fields

In addition to the above major fields, hydraulic bearings are also widely used in other fields. For example, in the aerospace field, the high precision and high reliability of hydraulic bearings can meet the requirements of work in extreme environments; in the field of power machinery, the high bearing capacity and long life of hydraulic bearings can ensure the long-term stable operation of equipment.

Traditional bearings: suitable for relatively low performance requirements of the occasion, such as general mechanical equipment, household appliances and so on. In this field, traditional bearings are widely used for their economy and easy maintenance.

In summary, hydraulic bearings compared with traditional bearings in the structure, performance characteristics and scope of application, there are significant differences. When choosing bearings, it is necessary to make comprehensive consideration and evaluation according to specific application scenarios and requirements.
