Custom Bearing Disc Spring Manufacturer - Grooved/Grooveless Preload Spring Supply

Looking for a reliable custom Bearing Disc Spring manufacturer for bearing pre-tightening? We specialize in producing high-precision grooved and grooveless bearing preload disc springs, with a classic annular design that ensures uniform load when multi-plate parallel connection. Our products support customization of dimensions, thickness and preload parameters, realizing load multiplication with the same displacement to fit the pre-tightening needs of different bearing models (deep groove ball, angular contact, tapered roller bearings). We use premium materials like 65Mn, 50CrVA and SUS304, and offer phosphating, dacromet and blackening surface treatments. Our bearing disc springs are applied to precision machinery, automotive and aerospace bearing assemblies, with stable preload performance and long service life.

Our manufacturing process adheres to strict quality control standards, ensuring each spring meets the required specifications for hardness, elasticity, and fatigue resistance. With advanced production equipment and experienced technical teams, we can handle both small-batch custom orders and large-scale production demands. Our engineers work closely with clients to optimize spring designs based on specific application scenarios, providing professional solutions for various preload requirements. In addition to standard products, we also offer special-shaped disc springs and composite spring systems to meet unique industrial needs. Through continuous innovation and technological upgrades, we aim to deliver superior bearing preload solutions that enhance the overall performance of mechanical systems.

1. Ball bearing disc spring are available in two different styles.
   Sloted Ball Bearing disc spring.
   Plain Ball Bearing disc spring.
2. Material: Alloy steel, carbon steel
3. Surface treatment: Phoaphating, oxidize, polishing
4. The specification is available on the table below
5. We can customize disc spring as per customer's requirements.
6. Usage: It is widely used hydraulic parts, pumps, bearing preload, machinery, textile machinery, etc. Ball bearing disc springs are specially designed as preloading springs for use with radial ball bearings. They help maintain positioning accuracy of the bearing with no end play. They also minimize vibration and shaft deflection. Proper preloading will increase bearing rigidly and eliminate excessive running noise.
