Double row cylindrical roller bearing SKF classification

These bearings are of two forms:

(1) NN0000 type double row cylindrical roller bearing

These bearings are compact structure, load bearing deformation when small, through the working temperature recognition of the bearing fault so especially suitable for spindle bearing. Because of its outer ring no raised edge, so can separately installs outer ring and inner circle components (with roller and keep frame), do not restrict shaft or shell of the axial displacement, and the radial dimensions of the same single than cylindrical roller bearing, can accept more of the radial load.

(2) NN0000K type KongShuang cone listed cylindrical roller bearing

The bearing compact structure, bearing appear the following, speak the weaknesses of do not continue to use when loads deformation is small, so are suitable for machine tool spindle bearing. Bearing in the hole for cone, can trace adjustment bearing radial clearance.

The bearing outer ring because no raised edge, so it can separately installs outer ring and inner circle components (with roller and keep frame), do not restrict shaft or shell of the axial displacement, and the radial dimensions of the same single cylindrical roller bearing compared, can accept more of the radial load.
