Anneau de retenue

Bienvenue sur le Retaining Rings catégorie à 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—notamment DIN 471 (External Circlips for Shafts), DIN 472 (Internal Circlips for Bores), et 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 et BS, ensuring seamless integration into high-speed rotating equipment and structural housings. Fabricated from high-grade Acier à ressort (65Mn) ou Acier inoxydable (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 Oxyde noir (phosphate), Zingage blanc, et Dacromet. Grâce à nos chaînes de production de pointe, directement en usine, nous assurons fabrication sur mesure 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.
