Such bearings in the same size deep groove ball bearings, can take greater radial load, speed limit closer to the deep groove ball bearings, bearing such an isolated type, installation and removal extremely convenient, with compact structure, rigid, and by loading the advantages of small deformation.

In addition to my company produces a wide series cylindrical roller bearings, the production also filled with cylindrical bearings
