Bearing Preload Disc Spring is specially engineered for bearing pre-tightening applications and is available in two core series: grooved and grooveless types. It features a simple and durable annular design. When multiple plates are connected in parallel, this disc spring ensures uniform load force distribution, eliminating uneven stress on bearing components.

The most prominent advantage is its load multiplication performance. With the same displacement volume, the bearing load increases by multiples, perfectly meeting the high-preload requirements of industrial bearings.

Made from high-quality spring steel and stainless steel materials, it supports multiple surface treatments to enhance corrosion resistance and is widely used in all types of precision bearing assemblies of mechanical equipment.
