Product description:

Double row cylindrical roller bearings have two types of structures: cylindrical and tapered holes (code K).

There are two main types: NNU design and NN design.

The NN type design has double ribs on the inner ring and no ribs on the outer ring. The NNU shaped design has no blocking edges on the inner ring and double blocking edges on the outer ring. The conical hole structure can adjust the radial clearance during installation. Double row cylindrical roller bearings allow for a certain axial displacement between the shaft and the bearing seat, and can be used as non positioning bearings.

This type of bearing has the advantages of compact structure, high rigidity, high load-bearing capacity, and small deformation after being loaded, making it suitable for supporting machine tool spindles.
