CYLINDRICAL ROLLER BEARING

The roller bearings of cylindrical roller bearings are usually guided by two sides of a bearing ring. The cage, roller and guide ring are composed of a combination, which can be separated from another bearing diagram and belong to a separable bearing. This kind of bearing is more convenient to install and disassemble, especially when the inner and outer rings and axle and housing are interference fit.
Such bearings are generally only used to bear radial loads, but only single row bearings with both inner and outer rings can bear smaller directional axial loads or larger intermittent axial loads.
Compared with deep groove ball bearings with the same shape and size, the bearing has larger radial load capacity. However, the processing of the relevant parts such as shafts and shell holes with such bearings is very demanding.
Single column roller bearing, according to the difference of ring block, the inner ring has no block and the inner ring has two sides of N0000 (2000 type), the inner ring without retaining wall and the outer ring double block NU0000 (type 32000), the outer ring double block and the inner ring NJ0000 type (42000 type), the inner ring double block and the outer ring single block NF0000 type (1) Type 2000), outer ring with double sides, inner ring as single edge and flat retaining ring type NUP0000 (type 92000) and so on.
Double row cylindrical roller bearings are divided into two types: cylindrical inner hole and conical inner hole. It has the advantages of simple structure, good rigidity, large bearing capacity and small deformation after loading, and is suitable for machine tool support. NN and NNU two kinds of structural bearings do not restrict the relative axial displacement between the shaft and the shell. They are usually used as non position bearings.
FC, FCD and FCDP four row cylindrical roller bearings have high radial load capacity, but they can not bear axial force. Because the inner ring has no edge, the inner ring and outer components can be installed separately (with a full set of rollers and cage). Used in rolling mill or heavy machinery.
