Combined needle roller & thrust ball bearings

The NKX series combined bearings consist of a radial needle roller bearing and a thrust ball bearing. The steel ball and cage thrust assembly of the thrust ball bearing is the same as that of the unidirectional thrust ball bearings in the 511 series, allowing for relatively high-speed operation. Axial positioning in one direction is achieved through the outer ring flange. The steel ball-cage assembly and the shaft washer can be separated for installation. As there is no sealing structure to keep grease inside the bearing, lubrication with oil is required. These bearings are standardly supplied without a pressed steel shield.

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.
