Abstract:
1. A method for assembling adjustable bearing assemblies onto the axial ends of a mill roll having a roll portion with reduced diameter roll necks at each axial end, and an axial bore, comprising: disposing an axial center rod within said axial bore of the mill roll, said axial center rod having an axial length greater than the axial length of the mill roll; disposing tapered sleeves forming an inner ring for the bearing assemblies onto each roll neck of the mill roll; disposing a first bearing assembly including at least one outer ring and roller assembly within a non-adjustable end chock, said first bearing assembly having an axially open face for receiving the tapered sleeve mounted to a first roll neck of the mill roll, and an end-cover opposite from said axially open face, said end-cover having an axial opening for receiving an axial end of said axial center rod; positioning said first bearing assembly and said non-adjustable end chock on the first roll neck of the mill roll, such that said bearing assembly is in contact with an outer diameter surface of said tapered sleeve, and an axial end of said axial center rod passing through said axial opening in said end-cover; securing said first bearing assembly and said non-adjustable end chock to said axial end of said axial center rod; disposing a second and adjustable bearing assembly including at least one second outer ring and second roller assembly within an adjustable end chock, said second bearing assembly having an axially open face for receiving a second tapered sleeve mounted to a second roll neck of the mill roll, and an end-cover opposite from said axially open face, said end-cover having an enlarged axial opening for receiving a free axial end of said axial center rod; positioning said second bearing assembly and said adjustable end chock on the second roll neck of the mill roll, such that said bearing assembly is in contact with an outer diameter surface of said second tapered sleeve, and said free axial end of said axial center rod passing through said enlarged axial opening in said end-cover; securing said second bearing assembly and said adjustable end chock to the free axial end of said axial center rod; and establishing a bearing setting for said first and second bearing assemblies between said end chocks through said axial center rod.
