Bearing Disc Spring for Deep Groove Ball Bearings
Precision Light Load Preload Solution
This precision-engineered disc spring provides optimal preload for high-speed rotation stability in light-load mechanical systems including precision spindles, HVAC blowers, and dental handpieces.
Key Benefits
  • 28% enhanced radial flexibility compared to standard disc springs
  • 15-20 dB noise reduction at 10,000 RPM operation
  • Accommodates shaft misalignments up to 0.05mm
  • Stepless preload adjustment with minimal disc count (2-4 discs)
  • Load multiplication ratios of 2.3-3.8x at equivalent displacement
Technical Specifications
Material SUS304 Stainless Steel (18Cr-8Ni) with plain oiled surface treatment
Temperature Range -40°C to 120°C
Corrosion Resistance Passes 500-hour salt spray testing per ASTM B117
Outer Diameter 12-65mm
Inner Diameter 5-45mm
Thickness 0.3-2.0mm
Tolerance IT6级 (±0.03mm on critical dimensions)
Design Features
  • Precision-machined grooved annular structure (groove depth 0.3-0.8mm, groove width 1.2-2.5mm)
  • Uniform load distribution (±4% variance)
  • Validated for 10⁶ cycles with preload force retention exceeding 90%
  • Compatible with standard deep groove ball bearing series (6000, 6200, 6300)
Applications
Ideal for continuous-duty applications in household appliances (refrigerator compressors, washing machine motors), small precision motors (stepper motors, servo drives), and optical instruments (microscope stages, laser positioning systems).
Installation
Simplified installation via press-fit or snap-ring mounting, with optional anti-rotation tabs available for high-torque environments.
