Like all mechanical parts, shafts are subject to manufacturing and assembly tolerances that generally cannot be entirely eliminated even with extensive technical measures. Without compensation of these mechanical deviations, they can cause vibrations, noises, and stiffness, eventually reducing the lifespan of the connected units.
Our recently added aluminum and stainless steel couplings address these issues and include designs for positive and non-positive connections. Multiple bore diameters, various, stiffness and hardness levels of the coupling body as well as an optional keyway allow very specific customization for various applications. In general, all couplings compensate for offsets and misalignments, accommodate runout error and axial motion, and dampen vibrations and impacts to varying degrees.
