Double-row cylindrical roller bearings. Double-row cylindrical roller bearings come in two types: with a cylindrical or a tapered bore. As for those with a tapered bore, the specified amount of clearance can be obtained by adjusting the press-in distance. Some bearings are fitted with lubrication holes and lubrication grooves on the outer ring.
Double Row or Two Row Full Complement Cylindrical Roller Bearings are designed for heavier radial load carrying capacity than a same sized cage series bearing. The increase in rollers lends to the increase in capacity with a decrease in speed rating. Available in floating, single direction locating or two-direction locating, these bearings ...
Highly rigid Double-Row Cylindrical Roller Bearings for Lathe Main Shaft applications is the first-ever precision bearing to adopt an PPS resin cage (designated TB in NSK), while maintaining its functionality to deliver high accuracy & high rigidity in ultra high-speed applications.
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.

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.

Open cylindrical roller bearings are designed to tolerate heavy radial loads and light or intermittent thrust loads at speeds comparable to ball bearings. They are separable for easier fit and dismantling. Precision Machine Tool Double Row with Tapered Bore are designed to provide high rotational speeds and precise running tolerances with high reliability.
Designed as a thin wall type, the SL Model double-row cylindrical roller bearing supports enormous radial and impact loads. Therefore, it is ideal for use in parts subject to medium low-speed large loads. This bearing has various uses, such as in construction machinery, vehicles, steel machinery and lifting equipment, etc. ...

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.
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.
In addition to the information provided on this page, consider what is provided under Double row cylindrical roller bearings.; For information on selecting the appropriate bearing for a given application, and interpreting the data on this page, refer to Bearing selection process.; For general information on rolling bearings, refer to General bearing knowledge.
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.
