Features and advantages of QIBR needle roller bearing and thrust ball combination bearing, thrust bearing with cage
QIBR needle roller bearing and thrust ball combination bearing, thrust bearing with cage solves multiple key problems in various fields, 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
Needle roller bearing and thrust ball combination bearing, thrust bearing with cage can adapt to complex working environments, can work normally under high load, vibration, impact and other conditions, and adapt to load changes in different directions.
4. Improve overall stability
The structural design of the combined bearing can effectively reduce the deviation or vibration of moving parts and enhance overall stability.
The performance improvement and solution of QIBR needle roller bearing and thrust ball combined bearing, thrust bearing with cage
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 bearings and thrust ball combined bearings, thrust bearings with cages
1. Automatic transmission
Transmission: Needle roller bearings can withstand large radial loads, and thrust ball bearings can withstand axial loads. Therefore, combined bearings are often used in transmission components in automobile transmissions to help support and reduce friction and improve work efficiency.
2. Agricultural machinery
In agricultural machinery, such as tractors, seeders and harvesters, transmission devices often require high load bearing and compact design. Needle roller bearings and thrust ball combined bearings can meet these requirements. Due to the relatively harsh working environment of agricultural machinery, the high durability and load-bearing capacity of combined bearings are very suitable for this application.
3. Reducer
Reducers usually need to handle radial and axial loads at the same time, so combined bearings have important applications in this type of equipment.
4. Machine tool equipment
Combined bearings are also widely used in machine tool equipment, especially in situations where they need to withstand high radial loads and large axial loads. It can effectively reduce vibration, reduce noise, and improve production efficiency and machine tool precision.
