FRB BEARINGS DOUBLE ROW CYLINDRICAL ROLLER BEARINGS mainly in the NNU design and the NN design. The bearings are separable, i.e. the ring with integral flanges together with the roller and cage assemblies can be mounted separately from the other bearing ring or all bearing components can be mounted separately. This facilitates the mounting, inspection and maintenance of these bearings.
