Needle Roller Bearings With Machined Rings With Flanges, With An Inner Ring

Available with open ends (no seals) or with seals on one or both sides, and with or without an inner ring, the bearings feature a non-separable closed ring as a flange in configurations with D < 17mm (Fw < 10mm), an integral flange with an annular lubrication groove and one or more lubrication holes in the groove on larger bearings, typically in a single row design except for the double row RNA69 and NA69 series, and a non-separable unit composed of the needle roller and cage assembly and the outer ring with flange.

Features and advantages of QIBR machine-cut rings, needle roller bearings with ribs and inner rings

QIBR machine-cut rings, needle roller bearings with ribs and inner rings solve multiple 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 and 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 and 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 and inner ring are suitable for high speed applications and are not prone to excessive friction or overheating due to excessive speed.

The performance improvement and solution of QIBR machined ring, needle roller bearing with flange and 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.
