Introduction of Precision Needle Bearings:
The needle roller bearings are roller bearings with cylindrical rollers. Relative to its diameter, the roller is thin and long.This type roller called needle.Although with a small cross -section, the bearings still have high load tolerance.Needle bearing is equipped with a thin and long roller (the diameter of the roller is D≤5mm, L/D≥2.5, and l is the length of the roller), so when the radial structure is compact, its inner diameter size and load capacity are the same as other types of bearing, and the outer diameter is the smallest. It is particularly suitable for a supporting structure with limited diameter installation size.we produce different series,different needle bearing size needle roller bearing.
Pouring the outer ring needle roller bearing:The outer ring is formed with a thin steel plate, with small structural space and a large load capacity. It is suitable for the installation space to be restricted and the shell holes should not be used as rolling roads.
