Joint bearing characteristics The structure of joint bearing is simpler than rolling bearing, which is mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface. The joint bearing is generally used for low-speed oscillating motion (i.e. angular motion), because the sliding surface is spherical, it can also be tilted in a certain angle range (i.e. spherical motion), and can still work normally when the support shaft and the shaft housing hole are not concentric.

Self-lubricating spherical plain bearings are self-lubricating bearings that can be rotated or swung in any direction.
The self-lubricating spherical joint bearing is a kind of self-lubricating performance, that can be rotated or swung in any direction. It has the high bearing capacity, small coefficient of friction can automatically adjust the center can simultaneously withstand radial and axial load, self-lubricating maintenance-free, long service life, a wide range of applications, and other characteristics. Since the end of the last century, the product has been put on the market for the domestic water conservancy projects and various mechanical equipment to provide different specifications of self-lubricating joints bearing tens of thousands of sets, the actual use of many water conservancy projects proved that our company developed and produced a stable and reliable performance of self-lubricating joint bearing, in the national key water conservancy projects gradually replace the imported, representing the technology of domestic self-lubricating joint bearing reached the international advanced level!
Self-lubricating joint bearings are divided into three categories, namely radial joint bearings, thrust joint bearings, angular contact joint bearings
Self-lubricating thrust joint bearings
Self-lubricating materials have excellent friction reduction, wear-resistance and self-lubrication, and also have
High bearing capacity and good dimensional stability, can meet the special self-lubricating joint bearings for hydraulic machinery. The self-lubricating material has excellent friction reduction, wear-resistance and self-lubrication.

Spherical bearing, self lubricating

Joint bearings can withstand large loads. According to its different types and structure, it can bear radial load, axial load or radial, axial at the same time combined load. Due to the inner ring of the outer spherical surface with composite materials, so the bearing can produce self-lubrication in the work. Generally used for low-speed swing movement, and low-speed rotation, but also in a certain angle range for tilting movement, when the support shaft and shaft shell-hole is not the center degree is large, but still can work normally. Self-lubricating joint bearings are used in water conservancy, professional machinery and other industries.

Sphere Oscillating Bearing Introduction:

Product features:
The product has a high bearing capacity, small friction coefficient, automatic self-aligning, can bear radial and axial loads at the same time, no maintenance, long service life, wide application range, and so on.
Product Application:
The product is widely used in hydraulic machinery arc gates, plane gates, miter gates, a hydraulic hoist and tubular turbine water guide mechanism and other equipment.

Characteristics and application of joint bearing, oilless bushing supplier

The outer layer of the self-lubricating spherical joint bearing is a steel ball, which can be quenched to improve the load-carrying capacity, and the inner ball combines the wear resistance of copper alloy (ZCuZn24Al6, SAE430B) and the self-lubricating property of solid lubricant so that it does not need oiling and maintenance during the use. We also have an oil groove on the outside of the design so that it is easy to refuel, which can greatly improve the life of the product if it is in use, so the product is widely used in high load, intermittent, or rocking motion, such as steam locomotive production line, hydraulic turbine, reservoir work/accident door, plastic machinery, etc. Various types of copper alloys are available depending on the operating conditions used.

A plain bearing is a kind of sliding bearing with a special structure, which is mainly composed of an inner ring with an outer sphere and an outer ring with an inner sphere. It can swing and rotate in any direction. Generally, it can bear a large load and has the characteristics of high load-bearing, impact resistance, wear resistance, self-aligning and good lubrication.Because the outer sphere of the inner ring is usually inlaid with composite materials, the joint bearing can produce self-lubrication in operation. Generally used for low-speed swing motion and low-speed rotation, but also in a certain Angle range of tilt motion, when the supporting shaft and shaft shell hole concentricity is large, it can still work normally. Widely used in low-speed swing motion, tilt motion, and rotary motion, such as nuclear power, aerospace, engineering hydraulic cylinder, forging machine tools, construction machinery, automation equipment, automotive shock absorber, hydraulic machinery, and many other industries and fields, is the core components to determine the host operation performance.
