Product Description
Bearing Disc Spring vs Regular Disc Spring Technical Comparison
Bearing Preload Disc Spring (grooved/grooveless) represents a specialized engineering variant of disc springs, engineered with three critical differentiators from general industrial disc springs: precision-matched design, bearing-specific performance metrics, and application-tailored series classification.
Design Comparison
- Bearing Disc Spring: Standardized annular geometry with tight dimensional tolerances (±0.05mm on outer diameter) specifically engineered to interface with bearing inner/outer rings (ISO 492 tolerance class)
- Regular Disc Spring: Non-uniform dimensions optimized for general load applications
Performance Comparison
- Bearing Disc Spring: Multi-plate parallel configurations achieve uniform load distribution (±2% variance) and load multiplication efficiency (4-5x force output at equivalent displacement)
- Regular Disc Spring: Unpredictable load distribution (±8% variance) and linear force-displacement characteristics unsuitable for bearing pre-tightening
Series Specialization
- Bearing Disc Spring: Dedicated grooved series (with 4-8 radial stress-relief grooves) for high-speed precision applications (up to 15,000 RPM) and grooveless series for heavy-load scenarios (up to 800 kN static load)
- Regular Disc Spring: Lacks application-specific engineering
Constructed from bearing-grade alloys (50CrVA, SUS304) with fatigue life exceeding 10⁷ cycles, Bearing Preload Disc Springs remain the only elastic components validated for high-precision bearing preload in critical applications including machine tool spindles, automotive transmissions, and aerospace actuators.
