Round Gear Racks

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.

Round Gear Rack Material Optional

Round gear racks are available in various materials to suit different applications, each offering distinct benefits in terms of durability, performance, and environmental compatibility. The three main material options for round gear racks include steel, stainless steel, and plastic.

1. Steel
   Steel round gear racks are commonly made from materials like C45K carbon steel or St50K carbon steel, known for their exceptional strength and durability. These racks are ideal for heavy-duty applications, such as industrial machinery, automotive systems, and lifting mechanisms, where high load-bearing capacity and impact resistance are required. Steel gear racks are also cost-effective, making them a preferred choice for applications where material strength is prioritized over corrosion resistance.
2. Stainless Steel
   Stainless steel round gear racks, often made from 303-grade stainless steel, are designed for applications requiring enhanced corrosion resistance and durability. They are particularly well-suited for environments exposed to moisture, chemicals, or extreme temperatures, such as marine, food processing, or medical industries. Stainless steel racks provide long-lasting performance and require minimal maintenance, making them a reliable option for equipment operating in harsh or regulated conditions.
3. Plastic
   Plastic round gear racks are lightweight and ideal for low-load or sensitive applications where noise reduction and minimal wear are critical. Commonly made from high-performance polymers, these racks are used in medical devices, electronics, and lightweight automation systems. Plastic gear racks offer excellent resistance to corrosion and are cost-efficient for applications requiring low friction and reduced operational noise.
