Abstract

A method for assembling a set of bearing assemblies 100 onto a mill roll 10 and for establishing a required bearing setting. The mill roll 10 is configured to receive a set of bearing assemblies 100 at each axial end, with the bearing rolling elements 100A contained within supporting chocks 102 adapted for placement within a mill housing. The chock assembly 102R and bearing assembly 100 at a first end of the roll are positioned first, and coupled to the first end an axial center rod 22 passing through an axial bore 24 of the roll 12. The chock assembly 102L and bearing assembly 100 at the second end of the roll 12 is then positioned onto the opposite end of the roll 12, and a connecting sub-assembly 300, 400, 504A is secured to the second end of the axial center rod 22. The connecting sub-assembly engages the second chock assembly 102L and bearing assembly 100, and is adjusted to achieve a desired bearing setting for both bearing assemblies 100 through the center rod 22.
