Company plans for the immediate future in Alibaba platform, comprehensive new large-scale rolling mill bearings, sales promotion brand bearings.

Types mainly include: FCD NU NNU NN NCF NNF FC (SL) (RS) four row cylindrical roller bearing and six row cylindrical roller bearing.

Four-row cylindrical roller bearings and six-row cylindrical roller bearings are almost entirely for rolling mill roll neck, rollers and roller press. Compared with other roller bearings ，the bearings have lower friction.These bearings are normally with an interference fit on the roll neck, particularly suitable for steel rolling mill with high speed applications. The low bearing cross section allows you to use the same roller relatively large compared to the diameter of the neck diameter.Because of the very many rollers can be mounted, the radial load carrying capacity is very high. Multi-row cylindrical roller bearings can only accommodate radial loads. Therefore, these bearings and deep groove ball bearings and angular contact ball bearings, or radial or thrust designs of tapered roller bearings are installed, which bear the axial loads. 

Four-row and six-row tapered roller bearings are separable design, namely, bearings with integral flange ring and roller and cage assemblies can be installed separately from the pedestal, or all bearing components can be installed separately. This considerably simplifies bearing mounting, maintenance and inspection. Bearings can accommodate a certain limit the axial displacement of the shaft relative to the housing. Four-row cylindrical roller bearings with a cylindrical bore size bearings can also be supplied with a tapered bore. Bearings with a tapered bore can be adjusted during the installation process, determined in a certain radial internal clearance or preload.
