Features and advantages of QIBR double row full complement cylindrical roller bearings without outer ring

QIBR double row full complement cylindrical roller bearings without outer ring solves several key problems in various fields, which are mainly reflected in the following aspects:

1. QIBR double row full complement cylindrical roller bearings without outer ring High rigidity

QIBR double row full complement cylindrical roller bearings without outer ring Due to the dense contact between the roller and the inner ring, the rigidity of this bearing is relatively strong, which can provide stable support and precise operation.

2. QIBR double row full complement cylindrical roller bearings without outer ring Compact design

QIBR double row full complement cylindrical roller bearings without outer ring adopts a full-fill design, with a large number of rollers and a relatively small radial size, which can be used in places with limited space.

3. QIBR double row full complement cylindrical roller bearings without outer ring has high load-bearing capacity

QIBR double row full complement cylindrical roller bearings without outer ring Each roller almost contacts the load surface, so this bearing has a very high load-bearing capacity, which is particularly suitable for applications with heavy loads.

4. QIBR double row full complement cylindrical roller bearings without outer ring save space

The characteristic of QIBR double row full complement cylindrical roller bearings without outer ring is that it does not use an outer ring, but bears the load through the contact between the roller and the inner ring. This design makes the bearing more suitable for some applications with limited space.

5. QIBR double row full complement cylindrical roller bearings without outer ring save energy

QIBR double row full complement cylindrical roller bearings without outer ring reduce the friction between the outer ring and the inner ring: the design of direct contact between the roller and the inner ring reduces the friction between the outer ring and the inner ring, further reducing energy loss.

The performance improvement and solution of QIBR double row full complement cylindrical roller bearings without outer ring

1. Improve corrosion resistance

For bearings that need to work in harsh environments, especially when used in humid, chemical media or salt spray environments, QIBR double row full complement cylindrical roller bearings without outer ring can use stainless steel or other corrosion-resistant materials, or perform special corrosion-resistant treatment on the bearing surface (such as electroplating, coating, etc.), thereby extending its service life.
