Double row cylindrical roller bearings classification
Double row cylindrical roller bearings are divided into two forms:
⑴ NN0000 type double row cylindrical roller bearings
The bearing structure is compact, small deformation under load, it is particularly suitable for machine tool spindle bearing. Its outer wall, so you can install the outer ring and the inner components, respectively (with roller and cage), does not limit the axial displacement of shaft or housing, the same size and radial single row cylindrical roller bearings , can withstand greater radial load.
⑵ NN0000K type double row tapered bore cylindrical roller bearings
This kind of bearing structure is compact, small deformation under load and therefore suitable for machine tool spindle bearing. Bearing bore is tapered to micro adjust the radial clearance.
This kind of Slewing bearing outer ring without ribs due, it can be installed separately outer and inner components (with roller and cage), does not limit the axial displacement of shaft or housing, the same size and radial single row cylindrical roller bearings compared to withstand greater radial load.Good customer service not only include immediate response, instant delivery products, but also in communication with the customer calls the tone of many small aspects of the details. These aspects make, and very easy to bring a good reputation. Word of mouth is the best form of publicity, there is a good reputation, how can we not good business.
