Strut Mount Core Machining Precision: Tolerances & QC Standards

Strut Mount Core Machining Precision

The mount core fits inside the bearing inner ring. Accuracy determines performance.

Key Tolerances

• OD: ±0.05mm
• ID: ±0.05mm
• Face parallelism: ≤0.03mm
• Concentricity: ≤0.05mm
• Surface finish: Ra≤1.6μm

Inspection

• First article inspection
• In-process every 30 min
• 100% go/no-go gauge at final

Huami maintains ±0.02mm precision, exceeding industry standards.
