Radial spherical plain bearings

Radial joint bearing is a kind of spherical sliding bearing, which can withstand radial loads and can also make tilting or swinging motions within a certain angle range. Radial joint bearings are mainly composed of the outer ring, the inner ring, the sphere, and the retainer and other parts, and have the characteristics of compact structure, strong bearing capacity, and good self-lubricity. It has a wide range of applications in the field of mechanical engineering.

The working principle is: through the rolling and sliding of the sphere between the inner and outer rings, to achieve the rotation of the bearing and bear the load. When bearing radial loads, the contact points between the sphere and the inner and outer rings generate pressure, thereby transmitting the load. At the same time, it can also perform swinging and tilting within a certain angle range to adapt to different working environments and motion requirements. 

There are many types of joint bearings, and common types include:

GE series: such as GE50ES-2RS, where "GE" indicates the type of joint bearing, "50" indicates the nominal inner diameter, "E" indicates that the outer ring has an axial seam, "S" indicates that it has oil grooves and oil holes, and "RS" indicates that both sides are equipped with sealing rings.

GAC-S series: such as GAC-S60T, where "GAC" indicates the type of joint bearing, "S" indicates that the inner ring has threaded holes, "60" indicates the nominal outer diameter, and "T" indicates that the outer ring has a stop ring.

GX series: such as GX120S, where "GX" indicates the type of joint bearing, "120" indicates the nominal outer diameter, and "S" indicates that the inner ring has threaded holes. 

Features

Joint bearings can withstand larger loads. According to its different types and structures, it can withstand radial loads, axial loads, or combined loads that exist simultaneously in both radial and axial directions. Since composite materials are inlaid on the outer spherical surface of the inner ring, this bearing can produce self-lubrication during work. It is generally used in low-speed swing motion and low-speed rotation, and can also make tilting motion within a certain angle range. When the supporting shaft and the shaft housing hole have a large degree of different heartness, it can still work normally. Self-lubricating joint bearings are applied in water conservancy, professional machinery, and other industries.

Application

Joint bearings are widely used in engineering hydraulic cylinders, forging machines, engineering machinery, automated equipment, automotive shock absorbers, water conservancy machinery, and other industries. The joint bearing is a spherical sliding bearing, and the basic type is composed of an inner and outer ring with a spherical sliding spherical contact surface. According to its structure and type, it can withstand radial loads, axial loads, or combined loads that act simultaneously in both radial and axial directions.
