Joint bearing is a kind of spherical sliding bearing, whose sliding contact surface is an inner sphere and an outer sphere, which can rotate and swing at any Angle when moving. It is made of surface phosphating, blasting, padding, spraying and other special processing methods. 

Joint bearings can bear large loads. According to its different types and structures, it can bear radial load, axial load or radial and axial load. Because the outer sphere of the inner ring is inlaid with composite material, the bearing can be self-lubricating in operation.

Spherical Plain Bearing, also known as spherical plain or radial spherical bearing, is a type of plain bearing commonly used to accommodate rotational or oscillating movements in various industrial applications. It is designed to provide low friction and smooth operation in situations where there is misalignment or angular movement.

The key feature of Spherical Plain Bearing is its spherical inner and outer ring, with a sliding surface that allows for the transmission of radial and axial loads. This design enables the bearing to compensate for misalignment and accommodate oscillating or tilting movements. It is typically composed of an inner ring, an outer ring, and a spherical sliding surface made from materials such as steel, bronze, or PTFE (polytetrafluoroethylene) composite.

Spherical Plain Bearing is available in different sizes and configurations to accommodate various load capacities and operating conditions. It is commonly used in automotive, construction, agricultural, and industrial machinery applications, where it provides reliable performance in challenging environments.

In addition to its load-bearing capabilities, Spherical Plain Bearing offers easy installation and maintenance. Its simple design and self-lubricating properties make it a popular choice for many industrial applications.

In summary, Spherical Plain Bearing is a versatile and reliable plain bearing used in various industries. Its spherical design allows for misalignment compensation and smooth operation in situations with rotational or oscillating movements. With its ease of installation and maintenance, this bearing is a popular choice for applications that require low friction, durability, and the ability to accommodate misalignment.

Bearing classification:  

(1) GE... E type single seam outer ring, no lubrication groove. It can bear radial load and small axial load in any direction.

(2) GE... ES type single seam outer ring with lubricating oil groove. Variable speed bearings can bear radial loads and small axial loads in any direction.

(3) GE... ES-2RS single seam outer ring, lubricated oil groove, sealing ring on both sides. It can bear radial load and small axial load in any direction.

(4) GEEW... ES-2RS single seam outer ring, lubricated oil groove, sealing ring on both sides. It can bear radial load and small axial load in any direction.

(5) GE... ESN type single seam outer ring, lubricating oil groove, outer ring with a stop groove. Error 5 on quality judgment of TIMKEN bearing can withstand radial load and small axial load in any direction. However, when axial load is borne by the stop ring, its ability to bear axial load decreases.
