Advantages of needle roller bearings
Needle roller bearings are equipped with thin and long rollers. Therefore, the radial structure is compact.When the inner diameter and load capacity are the same as other types of bearings, the outer diameter is the smallest. It is especially suitable for the support structure with limited radial installation size.
Needle roller bearings should be combined with bearing rings and applications depending on the application occasions, machining accuracy and surface quality.
