Cylindrical Roller Bearing Description

Cylindrical bore and the conical bore two structures. This kind of bearing has a compact structure, rigidity, load capacity, force, deformation, etc, especially suitable for machine tool spindle bearing. It is divided into NN and NNU two structural forms. NN-type bearing a double wall of the inner and outer ring without ribs, NNU type of bearings, compared with a double wall of the outer ring while the inner ring without ribs, the two bearings shall restrict the axis and the relative axial displacement between the housing for non-locating bearings

Types of Cylindrical Roller Bearing

• Single row cylindrical roller bearings
• Double row  full complement cylindrical roller bearings
• Single row  full complement cylindrical roller bearings
• Four row cylindrical roller bearings  

   

• Features:

•  

• cylindrical roller line contact with the raceway, radial load capacity, both for load and impact load to bear weight, but also for high-speed rotation. Cylindrical roller bearing raceway and rolling element geometry improved after the design has a high carrying capacity, rib and roller end of the new structural design not only improves the axial load bearing capacity, while improving the roller face contact area with the wall lubrication conditions, and improve the bearing performance. Such bearings is mainly used for medium and large motors, generators, internal combustion engines, gas turbines, machine tool spindles, deceleration devices, handling machinery, all types of industrial machinery.
