Product Description

Product Detail

Needle bearings are roller bearings with cylindrical rollers that are thin and long relative to their diameter. Such rollers are called needle rollers. Although it has a small cross-section, the bearing still has a high load-bearing capacity. Needle roller bearings are equipped with thin and long rollers, so 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 support structures with limited radial installation dimensions.
Needle bearing is a very important mechanical part, and its application range is very wide. Whether it is automobile, aerospace, machine tool, electric power, metallurgy and other industries, needle roller bearings are needed to support and rotate mechanical parts to ensure the safety and reliability of equipment. Therefore, the quality and performance of needle roller bearings play a vital role in mechanical equipment in all walks of life
