Product Name：No Collar Slab Roller and Cage Assemblies
⊙This kind of bearing is suitable for the parts in which the radial size is specially limited. Since the bearing has not collar,
the surface of shaft journal and the surface of housing inner bore are directly acted as rolling face. It is requested that the
hardness, surface roughness and size accuracy of shaft journal surface and housing inner bore surface fitted with it be
adaptable to the collar of bearing. Another pivot cylinder is modified as flat cylinder with M-type cage structure. Its speed
performance is greatly improved.
