Round Gear Rack
Round gear racks function in the same linear action as square or rectangular gear racks but are cylindrical in shape. These gear racks are available in inch and metric pitch sizes and in C45K carbon steel, St50K carbon steel, and 303-grade stainless steel. Our precision round gear racks conform to DIN 867 / DIN 3972 for interchangeability and utilize a straight-toothed system with a 20-degree pressure angle. We standardly supply these in lengths ranging from 500mm to 2000mm, but custom lengths and configurations are available upon request. For more information or to get a quote on our round gear racks and spur gears, contact our customer support team, and we will gladly assist you!
