What is nk bearing?

1. Introduction to nk bearing
nk bearing is a bearing with cylindrical rollers. The ratio of the length to the diameter of the cylindrical roller is greater than 3. The diameter of the needle roller of the needle bearing is less than or equal to 5mm. Needle roller bearings are very suitable for bearing configurations with limited radial space.

2. Features of nk bearing
1. The cross section of the needle roller bearing is small, but it has a high load capacity, which is very suitable for bearing configurations with limited radial space.
2. The result of the correction of the line contact between the needle roller and the raceway can avoid the generation of destructive edge stress.

3. Application of nk bearing
Needle roller bearings are mainly used in elevator accessories, plastic machinery, office equipment, medical equipment, stepper motors, speed reduction devices and other fields.

4. The effect of temperature on the life of nk bearing
When the operating temperature of the needle roller bearing exceeds 120℃, the bearing parts will lose their original dimensional stability. Therefore, for bearings with an operating temperature higher than 120℃, special requirements can be made to HRB to select bearings that have undergone special heat treatment.
