Ball-bearing Pre-load Disc Springs
Ball-bearing Pre-load Disc Springs are manufactured from high carbon steel, heat treated for ultimate ductility and hardness and carry a phosphate and oil finish as standard.
If a more arduous corrosive application is required, then please contact us, where we will be happy to discuss various options.
Ball-bearing Pre-load Disc Springs are especially designed for use with radial ball bearings and maintain positioning accuracy of the bearing with no end play. These Springs minimise vibration and shaft deflection. Proper pre-loading will increase bearing rigidity and help eliminate excessive running noise.
Caution should be exercised if this type of Disc is used in a series stack arrangement (back to back). If the cone height / thickness ratio is 1.5 and above, the stack could be prone to collapse. |

Advantages of Ball-bearing Pre-loaded Disc Springs:
- Take up manufacturing tolerances
- Quietens bearings
- Reduces numbers of components and simplifies fitting
- Load evenly applied around bearing outer ring
- Automatic bearing alignment with a light pre-load
- Minimises axle space
- Small load change with axial deflection
