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).

Materials & Surface Treatments

Premium Materials: SUS304 (18-8 chromium-nickel) and 50CrVA (chromium-vanadium alloy steel)
Fatigue Resistance: ≥10⁷ cycles
Surface Treatments: Black oxide coating (per MIL-DTL-13924) and dacromet plating (ASTM B117 salt spray resistance ≥1000 hours)
Benefits: Enhanced corrosion protection and operational longevity in demanding industrial environments
