Retaining Ring

Welcome to the Retaining Rings category at MJ Anchor (Hebei DuoJia Metal Products Co., Ltd.), your premier technical manufacturer and global supplier located in Handan Yongnian, the heart of China’s fastener production industry. Drawing on the deep engineering heritage of our predecessor, the Yonghong expansion screw factory, we produce a comprehensive range of retaining rings—including DIN 471 (External Circlips for Shafts), DIN 472 (Internal Circlips for Bores), and E-Clips (DIN 6799)—specifically engineered to provide secure axial positioning and prevent component migration in machinery, automotive transmissions, and aerospace assemblies. Our retaining rings are precision-manufactured to comply with rigorous international standards, including GB, DIN, ANSI, and BS, ensuring seamless integration into high-speed rotating equipment and structural housings. Fabricated from high-grade Spring Steel (65Mn) or Stainless Steel (SS304/SS316), these fasteners are heat-treated to achieve optimal radial tension and fatigue resistance, allowing them to snap into pre-machined grooves with maximum stability. To guarantee long-term durability and protection against environmental degradation, our products feature professional surface treatments such as Black Oxide (Phosphate), White Zinc Plating, and Dacromet. With our advanced factory-direct production lines, we support custom manufacturing for non-standard thicknesses, specialized diameters, and unique material specifications based on your specific engineering blueprints. MJ Anchor is committed to providing reliable, laboratory-tested fastening components that meet the safety and precision demands of modern global manufacturing.
