Needle Roller Bearings

Each needle roller of the needle roller cage has a separate guide groove to correctly guide the needle roller to rotate. It is installed between the mandrel that can be used as a raceway surface and the inner diameter of the bearing housing. It is a self-contained rolling bearing that does not need to rely on the track surfaces of the inner and outer wheels of the bearing. When selecting the size, the inner diameter of the bearing housing and the diameter of the mandrel can be determined. The use of flat type bearings has a small outer diameter ratio, which is conducive to the miniaturization and light weight of the machine, and has a large load capacity.
There are many sizes, welcome to inquire.
