Double row cylindrical roller bearings have two types of structure: cylindrical and tapered bores (post code K). There are two main types: NNU design and NN design. The NN design has inner ring with two flanges and outer ring without flange, and the NNU design has inner ring without flange and outer ring with double flanges. Tapered bore structure can adjust radial clearance during installation.
Double Row. Two-row, or double-row, cylindrical bearings are designed for additional strength in carrying radial loads. These bearing types are interchangeable so the dimensions and diameter under the rollers (NNU style) and diameter over the rollers (NN style) are held to an ISO/DIN standard.

Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tools. Depending on the series as defined below a number of cylindrical roller bearings have no ribs on either the inner or outer ring, so the rings can move axially relative to each other which can be used as free-end bearings.
The separable components of SKF double row cylindrical roller bearings are interchangeable. This facilitates mounting and dismounting, as well as maintenance inspections. High speed capability The cage designs are suitable for high speeds, rapid accelerations and peak loads.
This roller bearing has a CN (normal) radial clearance for applications and operating conditions with normal shaft and housing tolerances where thermal expansion is not a factor. This is a double row roller bearing that supports higher radial loads than single row bearings. Open end design allows for lubrication to be applied in place.
CYLINDRICAL ROLLER BEARINGS Full-Complement Cylindrical Roller Bearings for Crane Sheaves NSK’s full complement double-row cylindrical roller bearings feature a thin-section profile and broad width specially designed for crane rope sheaves. Other applications include machinery operated at low-speed under a high load.
DY’s double-row cylindrical roller bearings are divided into bearings with cylindrical inner bore and tapered inner bore (added K behind bearing type). This type of bearing has these advantages, such as compact structure, good rigidity, heavy load carrying capacity, and little distortion under loads. Consequently, it’s applicable for the machine tool spindle.

last of the list most common point is SKF double row cylindrical roller bearings are interchangeable. This facilitates mounting and dismounting, as well as maintenance inspections.
A spherical roller bearing is a rolling-element bearing that permits rotation with low friction, and permits angular misalignment. Typically these bearings support a rotating shaft in the bore of the inner ring that may be misaligned in respect to the outer ring. The misalignment is possible due to the spherical internal shape of the outer ring and spherical rollers.
