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.
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.
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.
