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.
Characteristic
1. High radial load capacity,is suitable for heavy load and impact load.
2. Small friction, suitable for high speed,the limiting Speed is close to Deep Groove Ball Bearings
3. N,NU series can adapt to high temperature and allow error during installation.
4 .inner ring and outer ring are separable,easy to install and take down
Mainly use
Large and medium-sized motor, locomotives, spindle, internal combustion engine, generator, gas turbines, reducer, rolling mill, vibrating screen and lifting transportation machinery, etc.
Cylindrical roller bearing is separable. As their rollers linearly come into contact with inner ring and outer ring with less coefficient of friction, these bearings have very good capacity of radial load, suitable for electric motors, automobiles, transmission shafts, gear shafts and so on. Double row cylindrical roller bearings are good at the spindles of machine tools.
