Cross Roller Excavator Slew Ring Slewing Bearing-manufacture,factory,supplier from China

These bearings are widely used in the rotating parts of industrial robots, machine tools, medical equipment, etc., which requirecompactness, high rigidity and high rotational accuracy. In addition, bearings made of stainless steel and those with inner and outer rings provided with mounting holes are also available on request. Please contact us.Crossed Roller Bearings are compact bearings with their rollers alternately crossed at right angles to each other between inner and outer rings.

Structural features: The roller inside the cross roller bearing is combined in a cross arrangement, which makes the bearing able to withstand both radial and axial loads. There is a certain gap between the inner and outer rings, which can make the bearing maintain high rigidity when it is subjected to high torque load, and also has good rotation accuracy and stability. The design of the seal ring and cage of the cross roller bearing is also very important, which can effectively prevent dust and foreign matter from entering the bearing interior and extend its service life.

RU cross roller bearings are also known as bearings. The main body of a rolling body usually uses cylindrical or tapered rollers to intersect a single flow path, separated by retainers or spacers, and arranged in a cross pattern. Therefore, the cross roller ring group can withstand loads in all directions, with a stiffness of 3-4 times higher than traditional models. RU cross roller bearing is lubricated by spray. Drilled shrinkage air mixes spray and lubricating oil to produce oil mist.

Cross roller bearing is a special kind of rolling bearing, which is widely used in mechanical field. It is designed to meet large size equipment that needs to operate under the requirements of high load capacity, high rigidity and high rotational accuracy. The cross roller bearing is composed of inner and outer rings, rollers, sealing rings and cages, and its structural advantages are that it can withstand both radial and axial loads, with high torque rigidity and running accuracy. The following will introduce the characteristics and applications of cross roller bearings in detail.

Slewing bearing has four series of toothless, external and internal toothed four-point contact ball bearings, double row angular contact ball bearings cross cylindrical roller bearings, cross tapered roller bearings and three row cylindrical roller composite bearings, of which four-point contact ball bearings have higher static load capacity, cross cylindrical roller has higher dynamic load capacity, The pre-interference of cross-tapered roller bearing can make the bearing have greater support rigidity and rotation accuracy.

The single-row four-point contact ball slewing bearing has the characteristics of compact structure and light weight, which makes it widely used in construction machinery. Because the steel ball and the circular raceway contact at four points, this support can bear axial force, radial force and heeling moment at the same time, with high bearing capacity and stability. Applicable scope includes rotary conveyor, welding operator, small and medium-sized cranes, excavators and other construction machinery, is a multi-functional, efficient slewing support structure.

Bearing performance: The bearing capacity of cross roller bearings is large, suitable for high-speed and high-load applications. Due to the special arrangement of rollers, the bearing can share part of the load when bearing radial and axial loads, which improves the bearing capacity and stability.

Applications: Cross roller bearings are widely used in many fields, including machine tools, engineering machinery, medical equipment, food packaging machinery, etc. On machine tools, cross roller bearings are often used to support the spindle and the turntable to ensure the high-speed and high-load operation of the equipment.

Excavator bearing installation and removal methods, should be according to the excavator bearing structure, size and excavator bearing parts with the nature.Installation, disassembly pressure should be directly added to the end face of tight fit excavator bearing stalls circle, not by the excavator bearing rolling elements to transmit pressure, because this will be caused by the excavator bearing work surface indentation, impact excavator bearing normal workeven make excavator bearing damage.

Rotary bearing is an important mechanical component, which is widely used in various industrial equipment and mechanical devices. It bears the radial load, axial load and moment load under the rotating motion, and plays the role of support and rotation. The following will introduce the structure, working principle, application field and maintenance of the rotary support bearing in detail.Rotary support bearings are usually composed of an inner ring, an outer ring, a rolling element (ball, roller, etc.) and a cage.

Rotary support bearings are widely used in various mechanical equipment and construction machinery, such as cranes, rotary tables, machine tools, wind power equipment, drilling RIGS, excavators and so on. In these equipment, the rotary support bearing assumes the important role of supporting the rotating member, ensuring the normal operation of the equipment. At the same time, it is also widely used in high-end fields such as aerospace, ocean engineering, and automated production lines.

High Rigidity Type Crossed Roller Bearing V has a solid one-piece construction for both inner and outer rings. Therefore, high accuracy and high rigidity are achieved, and mounting errors can be minimized. As separators are incorporated between the cylindrical rollers for smooth rotation, these bearings are suitable for applications where rotation speed is comparatively high.

When the rotary support bearing is working, the inner and outer rings realize relative rotation through the combination of rolling elements. When the external force acts on the bearing, the load is transmitted to the inner and outer rings, and is transmitted to each other through the rolling element, achieving the carrying capacity. At the same time, the rolling motion of the rolling element reduces the friction force and improves the rotation efficiency of the bearing.

This type of bearing is widely used in industrial automatic robots, working machinery and medical facilities, where high rigidity, tightness and high speed are required to ensure accuracy.

Construction machinery bearings have the following characteristics and scope of application:High strength and wear resistance: Construction machinery bearings usually need to withstand high speed and high load, and work in harsh environments, so they need to have high strength and wear resistance.High temperature resistance: Construction machinery bearings usually work in high temperature environments, so they need to have good high temperature resistance to ensure that bearings can still operate normally at high temperatures.High rotation accuracy: Construction machinery bearings require high

There are two main types of bearings widely used in industrial robots: constant cross-section thin-walled bearings and RU cross roller bearings. The bearing of an industrial robot is one of the key components suitable for the joints of industrial robots or the turntables of machining centers, robots, medical devices, measuring instruments, IC manufacturing equipment, etc., and has a wide range of uses.

When the rotary help bearing is working, the internal and outer rings recognize relative rotation thru the aggregate of rolling elements. When the exterior pressure acts on the bearing, the load is transmitted to the internal and outer rings, and is transmitted to every different via the rolling element, attaining the carrying capacity.

The structure of Koyo tapered roller bearings mainly includes an outer ring, an inner ring, a rolling body (roller) and a cage. The rolling element is located between the inner ring and the outer ring and is kept in the specified axial position by the cage. The contact Angle between the inner ring and the outer ring is generally between 10° and 30°, and different contact angles will affect the bearing capacity and speed limit.

Koyo tapered roller bearing is a common rolling bearing, usually used in automobiles, mechanical equipment, wind turbines and other fields.
