High Stiffness Bearing Disc Spring - Grooveless Series for Heavy-load Bearing Preload
Our Grooveless Bearing Disc Spring is the perfect choice for heavy-load bearing pre-tightening applications, with a solid annular design that delivers high stiffness and excellent load-bearing capacity. As a core series of bearing preload disc springs, it ensures uniform load force when multiple plates are connected in parallel, and its outstanding performance of load multiplication with the same displacement meets the high-preload requirements of heavy-duty mechanical bearings (tapered roller, spherical roller bearings). Made from high-strength 50CrVA and 60Si2MnA spring steel, it undergoes professional heat treatment to enhance fatigue resistance, and the phosphating surface treatment improves wear and corrosion resistance in harsh industrial environments.
This series is specifically engineered to address the challenges of heavy-load scenarios, ensuring consistent performance even under extreme pressure. Its grooveless design eliminates stress concentration points, significantly extending the service life while maintaining dimensional stability. The precision manufacturing process guarantees tight tolerances, enabling seamless integration into complex mechanical systems. Furthermore, its adaptability to various installation configurations makes it a versatile solution for applications requiring both high stiffness and reliable load distribution. Whether in mining equipment, large-scale gearboxes, or wind turbine systems, this bearing disc spring series provides an optimal balance of durability, efficiency, and operational safety.
