Definition of Needle roller bearings

Needle roller bearings are roller bearings with cylindrical rollers. The rollers are thin and long relative to their diameter.
This type of roller is called a needle roller. Despite having a smaller cross-section, the bearing still has a higher load bearing
capacity. The radial structure is compact. When the inner diameter size and load capacity are the same as other types of bearings,
the outer diameter is the smallest. It is especially suitable for the support structure with limited radial installation size.

Advantages of needle roller bearings

Needle roller bearings are equipped with thin and long rollers. Therefore, the radial structure is compact.
When the inner diameter and load capacity are the same as other types of bearings, the outer diameter is the smallest. It is especially suitable for the support structure with limited radial installation size.
Needle roller bearings should be combined with bearing rings and applications depending on the application occasions, machining accuracy and surface quality

Application of needle roller bearings

The needle bearings have a small cross-sectional height, which helps to ensure that the machine is both light and compact. Therefore, they have a wide range of applications, including automobiles, motorcycles, motors, machine tools, aerospace equipment, office equipment and other industrial machinery

Production processes
During the customer's order production process, we carry out processing inspection, the purpose is to do better quality control

Precautions for installation of needle roller bearings

The needle bearing has a large load-bearing capacity, which is suitable for the support structure with limited installation size. The surface of the journal is hardened as a rolling surface.
The bearing is press-fitted into the seat hole without axial positioning. The bearing should be filled with an appropriate amount of grease before installation.

Causes of needle roller bearing damage

In general, 33.3% of needle roller bearings are damaged due to fatigue damage.
33.3% of needle roller bearings are due to poor lubrication, and 33.3% are due to contaminants entering the bearings or improper disposal of equipment.
