Product Description
Grooved Bearing Disc Spring
Advanced Engineering for High-Speed Precision Bearing Preload
Our Grooved Bearing Disc Spring represents a specialized engineering solution designed for high-speed precision bearing pre-tightening. As one of two core product series in our bearing preload disc spring lineup, this product features a precision-machined grooved annular structure that delivers superior performance in demanding applications.
Key Engineering Features
- Radial Groove Design: 4-8 equidistant grooves with depth-to-thickness ratio of 0.3-0.5
- Enhanced Flexibility: 30% improvement in radial flexibility compared to conventional grooveless designs
- Optimized Stress Distribution: FEA-validated groove geometry for superior performance
- Vibration Reduction: Up to 25% reduction in vibration amplitudes
- Heat Management: 15-20% reduction in frictional heat generation during high-speed operation (exceeding 10,000 RPM)
Performance Specifications
When configured in parallel stacks of 2-6 discs, the spring assembly achieves uniform load distribution with ±2% tolerance and exhibits load multiplication characteristics (up to 5x force output with equivalent displacement). This ensures consistent preload maintenance for high-speed precision bearings including angular contact ball bearings (ISO 104) and deep groove ball bearings (ISO 62).
