Features and advantages of QIBR machine-cut rings, needle roller bearings with ribs but no inner ring

QIBR machine-cut rings, needle roller bearings with ribs but no inner ring solve several key problems in various fields, mainly reflected in the following aspects:

1. Compact structure

Due to the use of needle rollers as rolling elements, machine-cut rings, needle roller bearings with ribs but no inner rings have a relatively small volume while carrying large radial loads, and can be installed in a limited space, which is particularly suitable for compact mechanical design.

2. Low friction and high efficiency

Due to the precision design between the needle rollers and the cage, machine-cut rings, needle roller bearings with ribs but no inner rings have lower friction losses, reduced heat generation, and improved working efficiency. This makes it suitable for high-speed, high-efficiency working environments.

3. Strong durability

The cage can maintain the stable position of the needle rollers, reduce mutual contact and wear between the needle rollers, and thus extend the service life of the bearings. Reasonable clearance and precision design ensure the stability and reliability of the bearings at work.

4. Low noise and vibration

Due to the reasonable structural design between the needle roller and the cage, the possibility of contact between the needle rollers is reduced, and the noise and vibration of the bearing are reduced, so it is suitable for working environments that require low noise.

5. Adapt to high speed

Due to the small shape of the needle roller and the small contact area, the machined ring, the needle roller bearing with ribs but without inner ring is suitable for high speed applications and is not prone to excessive friction or overheating due to excessive speed.


Performance improvement and solution of QIBR machined ring, needle roller bearing with flange but without inner ring

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 running stability and efficiency.

Reduced contact area: By optimizing the geometry of the cage and the arrangement of the needle rollers, the contact area between the needle rollers is reduced, thereby reducing friction and wear.

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 precision, reducing the error between bearing components, and ensuring that the contact between the needle roller and the cage is more uniform and stable. This not only improves bearing performance, but also extends service life and reduces noise and vibration.


Main application areas of QIBR machine-cut rings, needle roller bearings with ribs but no inner ring

1. Agricultural machinery

Agricultural equipment: In heavy agricultural machinery such as tractors, tillers, harvesters, etc., machine-cut rings, needle roller bearings with ribs but no inner rings are used to provide strong load-bearing capacity and help reduce space occupation so as to adapt to small mechanical spaces.

2. Industrial machinery

Reducers and transmission devices: Machine-cut rings, needle roller bearings with ribs but no inner rings are widely used in reducers, gear transmission systems, etc., and can withstand large radial loads, reduce space occupation, and improve transmission efficiency.

Automation equipment: In the transmission system of automated production lines, machine-cut rings, needle roller bearings with ribs but no inner rings are used to support rotating parts to ensure the accuracy and stability of the equipment.

3. Aircraft engines

Machine-cut rings, needle roller bearings with ribs but no inner rings are often used on turbine shafts, turbines and other rotating parts in aircraft engines to ensure smooth operation at high speeds and withstand radial loads generated during high-speed rotation.

4. Washing machine

In the motor and transmission system of the washing machine, needle bearings play a role in supporting and reducing friction.
