We offer professional custom dimension Bearing Preload Disc Springs (grooved and grooveless series) engineered to precisely match the pre-tightening requirements of all bearing models, including deep groove ball, angular contact, tapered roller, spherical roller, and specialized miniature bearings.
Our engineering team provides comprehensive customization services, tailoring:
Each custom spring features precision machining with IT5级 tolerance control (±0.02mm on critical dimensions) to ensure exact interfacing with bearing inner/outer rings.
Our customization capabilities extend to material selection and surface treatments to address extreme operating conditions:
The development process includes FEA simulation validation, prototype testing with load-displacement curve certification, and full material traceability documentation. Typical delivery cycle for custom orders is 10-15 business days, with rush options available for critical applications.
These engineered solutions are widely adopted in specialized bearing assemblies for aerospace actuators, medical equipment, robotics, and heavy industrial machinery requiring non-standard preload configurations.
