Cylindrical roller bearing

Through strengthen type, completely logarithmic curve rolling elements and internal optimized design, SYB lets bearing with high loading capacity, low fiction coefficient and minimized resistance, etc, it greatly improves the bearing life and reduce the maintenance cost.

Dimension:

Inner bore diameter ≥ 80mm

Outer bore diameter ≤1500mm

Precision grade: P6，P5，SP,UP,P4

Type

1.N/NU/NJ/NF/NP/NUP/RN/RNU   Single row

2.NN/NNU/NNUP                Double row 

3.FC/FCD/FCDP                Four row 

4.NCF/NNC/NNCF/NNCL/NNF/SL  Full complement

Design character

1.The contact between roller and raceway is line contact, has good radial loading capacity, it applies to bear heavy load and impact load. 

2.Low friction coefficient, it is adapt to high speed, its limit rotating speed approaches deep groove ball bearing. 

3.N type or NU type can do axial movement, they can apply to the relative position change between shaft and housing because of thermal expansion and installation error, it can be used to support free end.

4.Cylindrical roller bearing has high requirement of shaft or housing hole, the relative tilting should be controlled strictly after assembling in case of concentrated stress.

5.Inner ring or outer ring can be separated, it is easy to be assembled and disassembled.
