SPIETH Adjustable Hydrodynamic Guide Bushings offer accurate guiding, adjustable guide clearance, and a hydrodynamic lubrication effect. They provide optimum guiding of axially or roto-axially moving machine components on round column axles, quills, boring bars, and similar round ways.
The cylindrical shape of the bushings allow for simple machining of the mating parts, thus reducing cost by straight boring or reaming. Grinding or scraping is seldom required.
