Double row cylindrical roller bearings' inner ring and outer ring are separable. These bearings have advantages like compact structure, high stiffness, high load carrying capacity, low stress deformation and so on.

Double row cylindrical roller bearings is the best type for machine tools. Tapered bore can adjust the clearance, simplify structure, easy to mounting and disassemble.

Shape Design

NN--Outer ring without ribs, inner ring both sides have ribs, middle rib in the middle. Axial displacement of the shaft with respect to the housing can be accommodated in both directions within the bearing itself .

NNU--Outer ring both sides have ribs( middle rib). Inner ring without ribs. This type is suitable as free-end bearings.

Cage Design

M--Combined alloy brass cages.

As a professional cylindrical roller bearings manufacturer and supplier in China, we can supply single row cylindrical roller bearings, double row cylindrical roller bearings, four row cylindrical roller bearing and other roller bearings.

• 
• Single Row Cylindrical Roller BearingsSingle row cylindrical roller bearings' roller and raceway are line contact. Bearings can accommodate heavy loads, radial loads mainly. Roller and ring rib has little friction, suitable for high speed rotation. Depending on the existence of ribs on their rings, cylindrical roller bearings are classified into NU, NJ, NUP, N, NF and other single row cylindrical roller bearings.

• 
• Four Row Cylindrical Roller BearingsFour row cylindrical roller bearings have small bearing cross section, allow to use relatively large roll neck diameters in comparison with the roll diameter. Since quantities of rollers can be incorporated, the radial load carrying capacity is exceptionally high. The cylindrical rollers are in linear contact with the raceways. They have a high load capacity mainly radial loads.
