Ball transfers are utilized in material handling due to their ability to move in all directions. This feature makes them ideal for assembly lines that require products to make turns in the course of handling. They are also especially well suited for use at work stations, where they facilitate the rotation of heavy material in any direction. This eliminates the need for workers to lift or slide products to complete assembly work, providing equal access to all sides.

Martin Gregory offers over sixty different styles of ball transfers. Most units are constructed of carbon steel support cups holding approximately 80 1/8" carbon steel balls. On top of this base, a carbon steel retainer and 1" ball are placed and then covered with either a simple cover or a flange-designed cover. For units requiring a mounting stud, the simple covered units are pressed into a stud cup with the approximate size bolt protruding from the bottom. Variations to this configuration include larger main balls of 1 7/8" diameter, smaller main balls of 1/2" and 1" diameter, units made entirely of stainless steel, and customized bolt sizes based on customers' requests.
