1. Heat Treating – You Get What You Pay For! Precise Heat Treatment – Ensures long term durability and quality Dura Hub Assembly 295-513017 (BCA 513017K) Induction hardening is a surface heat- treating process. A ferrous metal work piece (from medium to high-carbon content) is heated by means of a high frequency electromagnetic field. The heated work piece is then quickly quenched to produce a hardened structure. Typical Chinese Hub Assembly No Heat Treatment – Soft metal will deform and fail. Studs Meet or Exceed SAE/ASTM Standards - Ensures quality and strength Low Quality Studs- No supplier mark

2. Manufacturing Process: Quality Control Factory Inspection of: Metallurgical composition Length and Roundness Measurement Profile Parallelism Taper Measurement QC and Testing (onsite): Bearing Life Testing – Predicts the relative bearing life. Friction & Torsion Testing - Determination of bearing rigidity and strength. Salt & Mud Simulation Testing – Tests the Bearing seal. Society of Automotive Engineers (SAE J2530) Impact Simulation Test – Evaluates impact properties of the Hub Assembly. Radial Tensional Test – Tests cornering force by applying a radial load.
