Double-row cylindrical roller bearings
Doublerow cylindrical roller bearings have two structures of cylindrical and tapered bore.
This type of bearings have compact structures,highstiffness,high loading capacity and little deformation, and are especially as main shaft bearings of machine tools.
TypeNN has inner ring with two ribs and outer ring with no ribs. Type NNU has outer ring withtwo ribs and inner ring with no ribs. The two types of bearings dont limit axial displacement of shafts or housings, so they are used as nonlocating bearings.Machined solid cages are
usually used in this type of bearings.
