Cylindrical roller bearing is mainly single row, there is also a double row and four columns. Single row cylindrical roller bearings by an outer ring, an inner ring, a cage and a set of roller. Roll by outer or inner ring spinning. Single row cylindrical roller bearing is separable bearing, convenient installation and disassembly, can use two rings closely, correction between roller and raceway contact wires can reduce the stress concentration.


Single row cylindrical roller bearing is a basic, complete, and there is also a cross roller.


International general basic cylindrical roller bearing has the following six kinds:


1, the types of anger: inner ring no guards, can separate components; Type 2, NJ: a guard, inner ring can separate components; 3, NU type: the inner ring and single edge flat collar, can separate components; 4, the types of anger + hj: inner ring no guards but helical baffle ring can separate components; 5, NJ + hj: inner ring has a single guard and helical baffle ring, can separate components; 6, N type: double defender of inner ring and outer ring separable components.

(1) basic centripetal short cylindrical roller bearing


Basic centripetal short cylindrical roller bearing, outer or inner ring and another ring, roller and cage component types of bearings is separable. P0 levels in accordance with this law, ISO5753 cylindrical roller bearing, can be divided into ring should be able to achieve the same exchange in the international scope. This normally only carry pure radial load, compared with the same size deep groove ball bearings, have larger radial load capacity. But meet the needs of the shaft and bearing hole processing is higher. The Angle of the internal and external azimuth error only allow 2 ° ~ 4 °.

1, the types of anger: inner ring no guards, can separate components; Type 2, NJ: a guard, inner ring can separate components; 3, NU type: the inner ring and single edge flat collar, can separate components; 4, the types of anger + hj: inner ring no guards but helical baffle ring can separate components; 5, NJ + hj: inner ring has a single guard and helical baffle ring, can separate components; 6, N type: double defender of inner ring and outer ring separable components.


Cylindrical roller bearing has the advantage of allowing the axial displacement is small, if there is no guard detachable collar, the axial displacement of two directions, if there is a guard, no guards displacement. In addition, the inner and outer ring of the guard cylindrical roller bearing can absorb a certain amount of axial load.
