Features and advantages of QIBR needle roller and thrust cylindrical roller combination bearings

QIBR needle roller and thrust cylindrical roller combination bearings solve multiple key problems in various fields, which are mainly reflected in the following aspects:

1. Compound load bearing capacity

This combination bearing can bear radial and axial loads at the same time, and is suitable for complex environments where two loads act at the same time during work, especially applications that need to bear torque and radial force.

2. Save space and simplify design

Since this combination bearing bears radial and axial loads at the same time, it is usually not necessary to use multiple bearings in the design to share different types of loads, thereby saving installation space.

In some compact designs, the use of this combination bearing can greatly simplify the assembly process, reduce the number of parts, and reduce manufacturing and maintenance costs.

3. Strong adaptability

The needle roller and thrust cylindrical roller combination bearing can adapt to complex working environments, can work normally under high loads, vibrations, shocks, etc., and adapt to load changes in different directions.

The performance improvement and solutions of QIBR needle roller and thrust cylindrical roller combination bearing 

1. Improved materials

Selection of high-performance materials: Using materials with higher hardness, wear resistance and corrosion resistance can significantly improve the durability and stability of bearings.

2. Optimized cage design

Cage structure optimization: Optimize the cage structure design to achieve better needle roller arrangement and uniform load distribution. Improving the cage structure can reduce the mutual collision of needle rollers and improve operating stability and efficiency.

3. Improved lubrication performance

High-efficiency lubricating materials: Use grease or lubricating oil that is more suitable for high temperature and high pressure environments to ensure that the lubricating oil can maintain stable performance under long-term work, thereby reducing bearing friction and improving durability.

4. Improved precision

Precision machining technology: By improving manufacturing accuracy and reducing the error between bearing components, ensure that the contact between needle rollers and cages is more uniform and stable. This can not only improve the performance of the bearing, but also extend the service life and reduce noise and vibration.

Main application areas of QIBR needle roller and thrust cylindrical roller combination bearings

1. Automatic transmission

In automatic transmission, this type of bearing is used to bear large axial and radial loads to ensure smooth operation of the transmission.

2. High-precision machine tools

In precision CNC machine tools, especially high-speed spindle parts, combination bearings are used to provide high rigidity and high precision to ensure processing accuracy and stability of machine tools.

3. Robotic arms

In industrial robots, especially joint parts that require high loads, combination bearings can provide higher torque bearing capacity to ensure the flexibility and stability of the robot arm.

4. High-speed rotating equipment

For example, in high-end sports equipment such as skiing, racing, and sailing, combination bearings can provide precise rotation control and stability to ensure sports performance and safety.
