Bearing Disc Spring for Angular Contact Bearings: Engineered for Stable Preload Control and Vibration Damping in Precision Applications
Product Overview

Our Bearing Preload Disc Spring serves as the ideal dedicated component for angular contact bearing assemblies operating at high speeds up to 20,000 RPM. Engineered to maintain rotational accuracy (≤0.002mm runout) and minimize vibration amplitudes (≤0.01mm peak-to-peak), this precision component ensures optimal performance in demanding applications.

Design Features
  • Available in grooved (high-speed) and grooveless (heavy-load) series
  • Precision-machined annular design with tolerance class IT5
  • Perfect interface with angular contact bearing raceways (ISO 104 specification)
  • Uniform load force distribution with ±2% variance in parallel stacks of 2-8 discs
  • Load multiplication with the same displacement for stepless preload adjustment (500N to 5000N)
Technical Specifications

Constructed from 50CrVA alloy steel with tensile strength of 1250-1400MPa and hardness HRc 45-50. Features black oxide surface treatment compliant with MIL-DTL-13924, providing 72-hour salt spray resistance. Maintains stable preload force (±3% variation) over 10⁷ fatigue cycles.

Performance Benefits

Field validation in CNC machine tool spindles (e.g., DMG MORI NTX series) and precision servo motors (1.5kW to 15kW) demonstrates 30% reduction in bearing vibration and 40% extension in maintenance intervals compared to conventional wave washers. Accommodates diverse precision requirements from ultra-precision spindles (≤1μm axial runout) to heavy-duty gearboxes.
