Abstract
A bearing assembly is disclosed for rotatably supporting a quill in the housing of a rolling mill laying head. The bearing assembly comprises first and second axially spaced roller bearing sets interposed between the quill and the housing. A radial preloading force is applied to the first bearing set at a first location around its circumference. The preloading force is opposed by a reactionary force acting on the second bearing set at a second location around its circumference disposed 180° from the first location.

A bearing assembly for rotatably supporting a quill in the housing of a rolling mill laying head, said bearing assembly comprising:
- first and second axially spaced roller bearing sets interposed between said quill and said housing;
- and
- force exerting means for applying a radial preloading force to said first bearing set at a first location around the circumference thereof, said preloading force being opposed by a reactionary force acting on said second bearing set at a second location around the circumference thereof disposed 180° from said first location.
A method of reducing clearances between the components of a bearing assembly rotatably supporting a quill in the housing of a rolling mill laying head, said method comprising:
- subdividing the bearing assembly into axially spaced roller bearing sets;
- and
- applying a preloading force to one of said bearing sets at a first location around the circumference thereof, and opposing said preloading force with a reactionary force applied to the other of said bearing sets at a second location around the circumference thereof disposed 180° from said first location.
