Reducing bushes for encoders is a product category rather than a specific brand, commonly used in industrial automation and motion control systems. These components are typically manufactured by various companies specializing in motion control and encoder solutions, such as SICK AG (Germany), HEIDENHAIN (Germany), or Renishaw (UK). Reducing bushes serve as adapters to mount encoders onto shafts of different diameters, ensuring precise alignment and secure attachment. They are widely used in industries like manufacturing, robotics, CNC machinery, and automotive systems. Major suppliers like Radwell and Grainger distribute these components as part of their industrial automation product lines.
