Cylindrical roller bearings from the reliable CHG Bearings manufacturer
The advantages of the double-row cylindrical roller bearings are high stiffness and high precision, so they are usually used as main shaft bearings of precision machine tools.
Four row cylindrical roller bearings are especially applied to rolling mills required high speed and precision, for example, wire mills, bar and shape mills, cold or hot sheet mills and cogging mills.
Types of Cylindrical Roller Bearings:
NU Design - Outer ring has two integral flanges, while inner ring had no flange.
N Design - Inner ring has two integral flanges while outer ring has no flange.
NJ Design - Outer ring has two integral flanges and inner ring has one integral flange.
NUP Design - Outer ring has two integral flanges and inner ring had one integral flange & loose flange ring for both side axial locations
The rigidity in carrying radial load in the NNU and NN types make them applicable for machine tool spindles.
FC, DCD and FCDP type can carry comparatively heave radial load and are mainly applied for mill rolls.
If you have some cylindrical roller bearings or other type bearings , welcome to inquiry us , we will do our best to support, Thanks
Application of rolling mill bearingsFeb 28, 2024Rolling mill bearings should be selected according to the type and working characteristics of the rolling mill. 1. Billet opening machine and billet mill: This type of rolling mill generally has a large rolling force and strong impact load, but the speed is not high;
