GEH 110 ES-2LS bearing Spherical plain bearing  

Joint bearing is a type of spherical sliding bearing, with a sliding contact surface consisting of an inner spherical surface and an outer spherical surface. It can rotate and swing at any angle during motion. It is made using various special processing methods such as surface phosphating, blasting, gasket insertion, and spraying. Joint bearings have the characteristics of high load capacity, impact resistance, corrosion resistance, wear resistance, self centering, and good lubrication.

Basic information

The structure of joint bearings is simpler than that of rolling bearings, mainly consisting of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface. Joint bearings are generally used for low-speed swinging motion (i.e. angular motion). Due to the spherical sliding surface, they can also perform tilting motion (i.e. centering motion) within a certain angle range. They can still work normally when the supporting shaft and the shaft shell hole are not concentric enough.

characteristic

Joint bearings can withstand large loads. According to its different types and structures, it can withstand radial loads, axial loads, or combined loads that exist both radially and axially. Due to the composite material embedded on the outer spherical surface of the inner ring, this bearing can generate self-lubricating during operation. It is generally used for low-speed swing motion, low-speed rotation, and can also perform tilting motion within a certain angle range. When the support shaft and the shaft shell hole are not concentric, it can still work normally. Self lubricating joint bearings are applied in industries such as water conservancy and professional machinery.

application

Joint bearings are widely used in engineering hydraulic cylinders, forging machines, construction machinery, automation equipment, automotive shock absorbers, water conservancy machinery and other industries. Joint bearings are spherical sliding bearings, which are basically composed 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 acting both radially and axially.

Due to the large spherical sliding contact area and inclination angle of joint bearings, as well as the special process treatment methods adopted by most joint bearings, such as surface phosphating, galvanizing, chrome plating or external sliding surface lining, gasket insertion, spraying, etc., it has a large load capacity and impact resistance, and has the characteristics of corrosion resistance, wear resistance, self centering, good lubrication or self-lubricating without lubricating dirt pollution. Even if installed incorrectly, it can work normally. Therefore, joint bearings are widely used for lower speed swing, tilt, and rotation movements.

The function of joint bearings

Due to the completely different structural form and working mechanism from rolling bearings, joint bearings have their own technical characteristics and maintenance requirements.

working temperature  

The allowable working temperature of joint bearings is mainly determined by the matching materials between the sliding surfaces of the bearings, especially the plastic sliding surfaces of self-lubricating joint bearings, whose load-bearing capacity tends to decrease at high temperatures. When the sliding surface material of a lubricated joint bearing is paired with steel, its allowable working temperature depends on the allowable working temperature of the lubricant. But for all lubrication and self-lubricating joint bearings, they can be used within the temperature range of -30 ℃ to+80 ℃ and maintain the correct bearing capacity.

obliquity

The inclination angle of a joint bearing is much larger than that of a general adjustable center rolling bearing, making it suitable for use in supporting parts with low concentricity requirements. The inclination angle of a joint bearing varies with the size, type, sealing device, and support form of the bearing structure. The inclination angle range of a general radial joint bearing is 3 ° to 15 °, the inclination angle range of an angular contact joint bearing is 2 ° to 3 °, and the inclination angle range of a thrust joint bearing is 6 ° to 9 °.

cooperate

In any case, the selected fit of the joint bearing shall not cause uneven deformation of the ring. The selection of its fit properties and grades must be determined based on the working conditions of the bearing type, support form, and load size.

Loading and unloading

The loading and unloading of joint bearings should follow the following principles, that is, the force applied during assembly and disassembly cannot be directly transmitted through the spherical sliding surface. In addition, auxiliary loading and unloading tools such as sleeves and dismantling tools should be used to directly and uniformly apply the external loading and unloading force to the matched ring, or to use auxiliary methods such as heating for unloaded loading and unloading.

install

When assembling the joint bearing series, it is necessary to pay special attention to the position of the outer ring dividing surface. To avoid direct load on the dividing surface, it is necessary to maintain the dividing surface at a right angle to the corresponding direction.

lubrication

When the speed generated by applying load and swinging motion is small, the oil fed joint bearing can be operated without lubrication. However, in general, it is necessary to regularly replenish oil and fat. It is recommended to shorten the lubrication cycle moderately during the initial installation and operation.

Oil free joint bearings can be used without lubrication. However, if lithium soap based grease is added before operation, the service life of the joint bearing can be further extended. If grease is injected into the space around the bearing, the joint bearing will be more effective in preventing the invasion of dust and foreign objects.
