product description
Joint bearings are spherical sliding bearings, and the basic type is composed of inner and outer rings with spherical sliding spherical contact surfaces. The joint bearing is mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface, which can bear a large load. According to its different types and structures, it can bear radial load, axial load or combined load in both radial and axial directions. Since the outer spherical surface of the inner ring is inlaid with composite materials, the bearing can produce self-lubrication during operation. It is generally used for low-speed swinging motion, and can also be used for tilting motion within a certain angle range. When the misalignment between the supporting shaft and the shaft housing hole is large, it can still work normally.
Self-lubricating joint bearings are used in water conservancy, professional machinery and other industries. Because the spherical sliding contact area of the spherical plain bearing is large, the inclination angle is large, and because most of the spherical plain bearings adopt special processing methods, such as surface phosphating, galvanizing, chrome plating or outer sliding surface lining, padding, spraying, etc. Therefore, it has a large load capacity and impact resistance, and has the characteristics of corrosion resistance, wear resistance, self-aligning, good lubrication or self-lubrication without lubrication and dirt pollution, and can work normally even if the installation is misplaced. Therefore, spherical plain bearings are widely used for low-speed oscillating motions, tilting motions, and rotational motions.
Rod ends
Spherical plain bearings and rod ends are available in various designs and with different combinations of sliding contact surfaces. Each design and combination has unique properties that make it particularly suitable for certain applications.

Rod ends
To select a bearing type, and to determine the required bearing size, the main factors that must be considered are the load, the load capacity of the bearing and the expected service life. The same is true when selecting rod ends.
According to the GB/T9161 standard, its types can be divided into: curved rod drive head rod end joint bearing (type code: SQ); straight rod drive head rod end joint bearing (type code: SQZ); single rod drive head rod End joint bearing (type code: SQD); left-handed internal thread assembly rod end joint bearing (type code: SLLB); left-handed external thread assembly rod end joint bearing (type code: SALB); left-handed bent rod type rod end joint Bearing (type code: SLLB); left-handed single rod type rod end joint bearing (type code: SQLD); rod end joint bearing with cylindrical welding (cylindrical type) (type code: SK); welding type with flat base Rod end joint bearing (square type) (type code: SF); rod end joint bearing with lock (type code: SLR).
By size series
Rod end joint bearing EH series (reinforced type); rod end joint bearing EG series (reinforced type); inch size rod end joint bearing normal series (dimension series code is Z); rod end joint bearing JK series (dimension series code is JK ). Its structural material code and clearance group code are like joint bearings.
Rod end joint bearings are mainly used for supporting parts that do not require high concentricity, high pressure on the working surface, and perform slow swing and rotary motion.
For detailed information on rod end joint bearings, please refer to GB/T304,1-2002, GB/T304,2-2002, GB/T304,3-21102, GB/12765-1991. Rod end joint bearings are sliding bearings, which are lubricated by wear-resistant non-metallic materials and lubricated by oil passages.
Internal thread series
Similar to GE20-ET, GE15-ET, etc. are joint bearings, and the suffix is the specific type.
Joint bearings are divided into GE, GEC, GEG, GEEW, GEK, GEH and other types, with different sizes and lubrication methods, which can be found in the classification of sliding bearings in the mechanical design manual.
Rod end joint bearings in the narrow sense should refer to what is commonly referred to as fisheye joints.
The difference between the inner and outer wires of the fisheye joint according to the connection method is: the inner thread series SIG, and the outer thread series SAG. The size of the inner and outer wires is the same as the inner diameter of the fish eye. For example, the fish eye joint with the joint M12, the inner diameter of the bearing is also D12.
External thread series
Joint bearings are widely used in engineering hydraulic cylinders, forging machine tools, construction machinery, automation equipment, automobile shock absorbers, water conservancy machinery and other industries.
