Product Description

 

Cross roller bearing

In crossed cylindrical roller bearings, the cylindrical rollers are arranged in two 90° V-shaped raceways at a 90°included angle 1:1, and the cylindrical rollers are separated by the spacer block. This structure makes a set of bearings It can bear radial load, axial load and overtuming load at the same time.
       This kind of combined bearing has a compact structure, and at the same time greatly simplifies the structure design of the bearing under the premise of ensuring structural rigidity. Most bearings can be pre-loaded before leaving the factory, which further facilitates installation and maintenance work. Therefore, cross 
cylindrical roller bearings.  It has the characteristics of high 
precision,high load and high rigidity,which is very suitable for the occasions where the space size is clearly restricted,such as the rotating  part  of  the  robot,the  joint  part  of  the  manipulator,the numerical  control  indexing  table,the  medical  equipment,and  the measuring  instrument.

 

Rotary table bearing

In the rotary table bearing, the radial raceway of a thrust/centripetal   Lshaped inner ring, the radial raceway of a thrust/centripetal seat ring  and  a set of radial cylindrical rollers form the radial part of the rotary  table bearing. The axial raceway of the thrust/centripetal Lshaped  
inner ring, the two axial raceways of the thrust/centripetal seat ring, 
and two sets of thrust cylindrical rollers and their retainers form the axial part of the rotary table bearing. The radial and axial combined structure of this series enable it to withstand radial load, bidirectional 
axial load and overturning moment. This series of bearings can be 
preloaded and can achieve high rotation accuracy, so it is particularly
suitable for CNC rotation workbenches, swing-angle milling heads, 
gear grinding machine workbenches and other workplaces that 
require high precision.
The inner ring and outer ring of this series of bearings are designed with   screw mounting holes, which makes the installation and fixing
very simple; at the same time, the bearing preload is adjusted according to the working conditions at the factory, so there is no need to adjust the installation preload during installation.
The inner ring and outer ring of the bearing are designed with lubricating oil holes, through which lubricating grease can be conveniently added and replenishing the inside of the bearing.
 

Harmonic reducer bearings

Harmonic reducer is mainly composed of harmonic generator, flexible wheel, rigid wheel three basic components, in addition to rigid bearing (cross roller bearing) and flexible bearing (thin wall deep groove ball bearing).
The inner hole of the flexible bearing is matched with the elliptical cam outer ring. The outer ring is elastically deformed by the ball to match the inner diameter of the opening of the flexspline.The gear on the outer periphery of the opening of the flexspline meshes with  the teeth of the rigid gear.The number of teeth of the rigid wheel is more than that of the flexible wheel.The flexible wheel and the rigid wheel are meshed on the long axis and separated on the short axis.The bottom of the flexible wheel is fixed at the output end, and the rigid bearing is installed at the output end of the reducer to connect with the outside. Harmonic reducer is usually used in robotics,machine tools,aerospace and other industries.Accuracy, rigidity and bearing capacity and other requirements are very high. So the processing accuracy and installation accuracy of each part of the harmonic reducer are very high,the same requirements for bearings are also very high. The most important things for a rigid bearing are its rigidity, reliability and precision of rotation. Before the rigid bearing delivering to customer, the bearing will be adjusted to a certain preload to ensure that the bearing is sufficiently rigid;The most important thing maximum radial deformation of the bearing.

Solutions

1. CNC Field
One of the important fields for the application of precision bearings. Precision bearings can be used in spindle bearings, guide rail bearings, screw bearings, and other parts of CNC machine tools to improve the machining accuracy and stability of the machine tool. For example, using precision bearings as spindle bearings can reduce spindle vibration and errors, and improve the quality and accuracy of the machined surface.

2. Robots field
Robots are high-precision and high-efficiency automation equipment, and the application of precision bearings is also essential. Precision bearings can be used in the joints of robots to achieve high-precision and high stability movements. For example, using precision angular contact ball bearings can increase the flexibility and accuracy of robots, and improve their motion performance.

3. Aerospace field
The aerospace field requires extremely high precision and stability of equipment, and the application of precision bearings in this field is also very important. Precision bearings can be used in landing gears, navigation systems, engines, and other parts of aerospace vehicles to improve the working accuracy and stability of equipment. For example, using precision cylindrical roller bearings can reduce the vibration and noise of aircraft engines, improve aircraft performance and safety.

4. Medical equipment
Medical devices also have high requirements for accuracy and stability, and precision bearings are widely used in this field. Precision bearings can be used as the core components of medical equipment, such as the probes of ultrasonic diagnostic instruments and the rotors of medical centrifuges, to improve the diagnostic accuracy and stability of the equipment. For example, using precision tapered roller bearings can increase the stability and accuracy of medical centrifuges, and improve medical effectiveness.
