NU2214EM Cylindrical Roller Bearing Separable Type Roller Bearing Gearbox 32514H Automobile Bearing

Category of cylindrical roller bearing

Cylindrical roller bearing type belongs to the separation bearing, installation and removal is very convenient. Cylindrical roller bearing can withstand the big radial direction load and suitable for use in high-speed operation situation. Such bearing Angle error of axis axis allows the inner ring and outer ring (gradient) is very small, only 2 \'4\'. Therefore, the axis and the machining precision of the bearing are relatively high, otherwise easy to appear in raceway contact parts uneven load or stress concentration. But the roller or raceway contact bus can reduce the stress concentration after modification.

Cylindrical roller bearing with roller according to the number of columns is different, can be divided into single row, double row and column cylindrical roller bearing, etc. Different structure. Different bearing structure but also in the position of the guard design. The commonly used cylindrical roller bearing has the following form: Single row cylindrical roller bearings, single row cylindrical roller bearing is separable bearing, easy to install and disassemble, both ring can be used in a tight fit, the correction between roller and raceway contact wires can reduce the stress concentration. Double row cylindrical roller bearings, double row cylindrical roller bearings belong to the floating bearing, its very convenient to install and disassemble separability. Both ring can be used in a tight fit. Double row cylindrical roller bearing almost no slope Angle are allowed.

Single-row cylindrical roller bearing

N,NU NJ,NF  

NJ type of bearing outer ring on both sides of the guard, inner ring unilateral guard. Can withstand a certain amount of one-way axial load. Within the outer ring of single guard, NF type ring on both sides of the guard. Also can withstand a certain amount of one-way axial load. Therefore, this kind of structure is suitable for axial positioning as a one-way bearing.
