Needle Roller Bearings High Quality

Needle roller bearings are a common rolling bearing product. It usually consists of outer ring, inner ring, needle roller and cage. Needle roller bearings are known for their excellent load-carrying capacity, high rotational accuracy and high rigidity. This makes it widely used in various industrial and mechanical applications. Needle roller bearings are suitable for applications with high speed, high load and limited installation space, including automotive transmission systems, engines, wind turbines, machine tools, etc. Needle roller bearings are available in different sizes and specifications to meet various application requirements. It is necessary to select appropriate needle roller bearing products according to specific application scenarios and requirements.

Needle roller bearings are a common rolling bearing whose characteristics include

● High load capacity

Needle roller bearings have a higher load capacity than sliding bearings and can withstand larger radial and axial loads.

● High rigidity

Because needle roller bearings use rolling to support and transmit loads, they have high rigidity, which is beneficial to reducing deformation and improving positioning accuracy.

● Suitable for high-speed operation

Needle roller bearings use rolling friction instead of sliding friction, so they are suitable for high-speed operation.

● Compact appearance

Needle roller bearings are small and suitable for installation in limited spaces.

● Uniform load distribution

Needle roller bearings have a large number of balls/rollers and are evenly distributed, which can effectively reduce local loads and extend service life.

In general, needle roller bearings are suitable for mechanical equipment that require high load, high speed and small installation space, and have good reliability and durability.

Some common needle roller bearing models include

NK series: NK5/10, NK12/16, NK25/20, etc.

NA series: NA4900, NA6910, NA4826, etc.

HK series: HK0408, HK1010, HK2520, etc.

RNA series: RNA4900, RNA6910, RNA4826, etc.

These models represent only a small part of the needle roller bearing models. In actual applications, there will be many more models with different sizes and specifications to choose from. When selecting a suitable needle roller bearing model, the selection needs to be based on the specific load, speed, installation space and other specific requirements.
