Abstract
A bearing block for a boring turbine, with ball bearings having intermediate spring rings between them: the spring rings have spring deflection characteristics such that the bearings are stressed in series sequence as the cutting force changes and such that each bearing is not stressed until the previous bearing in series has been stressed; for adjusting the deflection characteristic, some rings have varying size holes through them.
