Features and Performance of Spherical Plain Bearings


The joint bearings mainly include: angular contact joint bearings, thrust joint bearings, radial joint bearings, and stalk end joint bearings. The classification of joint bearings is mainly based on the direction, nominal contact angle and structural type that can bear the load.


What are the characteristics of radial spherical plain bearings


Spherical plain bearings can withstand larger loads. According to its different types and structure, it can bear radial load, axial load or combined load of radial and axial. Since the outer spherical surface of the inner ring is covered with composite material, the bearing can produce self-lubrication during operation. It is generally used for low-speed swing movement and low-speed rotation, and can also be used for tilting movement within a certain angle range. 


It can still work normally when the support shaft and the shaft shell hole are not centered. Self-lubricating joint bearings are used in water conservancy, professional machinery and other industries.

 

1.GE…E type only meets the outer ring without lubricating oil groove. Can withstand radial loads and smaller axial loads in either direction.

 

2.GE…ES type single-slit outer ring with lubricating oil groove. Can withstand radial loads and smaller axial loads in either direction.

 

3.GE…ES-2RS single-slit outer ring, with lubricating oil groove, with sealing rings on both sides. Can withstand radial loads and smaller axial loads in either direction. Need bearing GE50ES-2RS, 23234CC/W33 pls click here.

4.GEEW...ES-2RS single-slit outer ring, with lubricating oil groove, with sealing rings on both sides. Can withstand radial loads and smaller axial loads in either direction.

 

5.GE…ESN type

 

Single-slot outer ring with lubricating oil groove and outer ring with stop groove. Can withstand radial loads and smaller axial loads in either direction. But when the axial load is borne by the stop ring, its ability to bear the axial load is reduced.

 

6.GE…XSN type

 

Double-slit outer ring (split outer ring), with lubricating oil groove, and outer ring with stop groove. Can withstand radial loads and smaller axial loads in either direction. But when the axial load is borne by the stop ring, its ability to bear the axial load is reduced.

 

7.GE…HS type inner ring has lubricating oil groove, double half outer ring, clearance can be adjusted after wear. Can withstand radial loads and smaller axial loads in either direction.

 

8.GE…DE1 type

 

The inner ring is hardened bearing steel and the outer ring is bearing steel. It is extruded during the assembly of the inner ring, with lubricating oil grooves and oil holes. Bearings with an inner diameter of less than 15mm, without lubricating oil grooves and oil holes. Can withstand radial loads and smaller axial loads in either direction.

 

9.GE…DEM1

The inner ring is hardened bearing steel and the outer ring is bearing steel. When the inner ring is assembled, it is extruded. After the bearing is installed in the bearing seat, the end groove is pressed out on the outer ring to fix the bearing axially. Can withstand radial loads and smaller axial loads in either direction.

 

10.GE…DS type

 

The outer ring has assembly grooves and lubrication grooves. Only for large size bearings. Can withstand radial load and smaller axial load in any direction (the assembly groove cannot bear axial load on one side).

 

Performance of angular contact spherical plain bearings

 

GAC... S type inner and outer rings are hardened bearing steel, and the outer ring has oil grooves and oil holes. Can bear radial load and axial (joint) load in one direction.

 

Characteristics of thrust joint bearings

 

GX... S-type shaft ring and seat ring are hardened bearing steel; the seat ring has oil groove and oil hole. Can withstand axial load or combined load in one direction (in this case, the radial load value should not be greater than 0.5 times the axial load value).

 

Applications of articulated bearings

 

Joint bearings are widely used in engineering hydraulic cylinders, forging machine tools, engineering machinery, automation equipment, automotive shock absorbers, water conservancy machinery and other industries. Spherical plain bearings are spherical plain bearings. 


The basic type consists of inner and outer rings with spherical sliding spherical contact surfaces. Depending on its structure and type, it can withstand radial loads, axial loads, or combined loads that act simultaneously in the radial and axial directions.

Because the spherical sliding contact area of the joint bearing is large and the inclination angle is large, but also because most joint bearings adopt special processing methods, such as surface phosphating, zinc plating, chrome plating or outer sliding surface lining, inserting pads, spraying, etc. Therefore, it has a large load capacity and impact resistance, and has the characteristics of anti-corrosion, wear resistance, self-aligning, good lubrication or no lubrication pollution by self-lubrication, even if it is installed incorrectly, it can work normally. 


Therefore, the joint bearing is widely used in swinging motion, tilting motion and rotating motion at low speed.
