needle roller bearings
Needle roller bearings use very long and thin cylinders. Often the ends of the rollers taper to points.The radial structure is compact, and its inner diameter and load capacity are the same as other types of bearings, and the outer diameter is the smallest. It is especially suitable for supporting structures with restricted radial installation dimensions.
