This article presents the structural concept of the shaft support system for vertical shaft machines, describing its design features, manufacturing process, and the functional role of the rubber element positioned between the bushings. The study also examines the improved lubrication system and explains the purpose of shaping the lower inner part of the housing in a hemispherical form, emphasizing the damping function provided by the rubber damper installed in this area. In addition, the paper investigates the twist angle of the helical grooves formed along the shaft in the direction opposite to shaft rotation, the operating rotational speed, and the influence of elastic components within the support assembly on deflection behavior. Experimental test results obtained using weight-based wear measurement techniques are presented to evaluate the durability and performance characteristics of the improved support structure.
