Product DetailNeedle 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 lifeProduct
