<p>A bearing block for a ball valve or the like which is held in place by clamping it between the valve body end closures. A pair of slots are disposed through the bearing block intermediate the bearing bore and its opposite, ends, and the dimensions of the bearing block outward of the slots are somewhat greater so that compressive forces are lighter in those areas within the ends projections of the bore. In one embodiment, the slots extend through to the ends of the bearing block and in another embodiment they terminate at both ends in drilled holes.</p> |
