Loose Needle Rollers

Needle roller bearings have a small cross-section, and they still have a high load bearing capacity. Needle roller bearings are equipped with thin and long rollers, resulting in a compact radial structure. Their inner diameter and load capacity are the same as those of other types of bearings, and their outer diameter is the smallest. They are particularly suitable for supporting structures with limited radial installation dimensions.
