Abstract
A centrifuge rotor includes a dynamically balanced casing assembly having upper and lower parts that define a hollow bowl with a continuous peripheral gap between such casing parts. The casing parts are held in position by a series of bolt assemblies which maintain the axial spacing. Each bolt assembly has a pair of portions respectively, rigidly secured to the casing parts, such bolt assembly portions having concentric interfitting surfaces, with a screw extending through one of said bolt assembly portions into the other. The concentric interfitting surfaces preferably include a step whereby precise location of the casing parts with respect to each other is achieved, even upon reassembly, thereby facilitating disassembly and reassembly as well as assuring maintenance of dynamic balance.
