Every incoming lot is checked against its mill certification before it enters production — steel chemistry, heat lot traceability and supplier documentation are verified, and sample components are dimensionally inspected and logged on the shop floor.

CMM, optical comparators, and dedicated gauge stations check every critical dimension through the machining sequence — bore, OD, raceway geometry, and width. Results are logged against the drawing so any deviation is caught before the part reaches final assembly.

Each bearing is tested for radial internal clearance and running noise on calibrated Anderon meters and vibration analyzers. We confirm smooth rotation, acceptable vibration velocity, and quiet operation so assemblies run cleanly in the final application.

Raceway finish and roundness are verified on Talyrond and profilometer systems. We measure waviness, surface roughness, and circular geometry to the levels required for low-torque, low-noise, and long-life performance — critical for high-speed spindles, precision robots, and medical devices.

Bearing rings and rolling elements are heat-treated to controlled profiles, then verified for through-hardness and effective case depth across every lot. Rockwell and microhardness testing confirm the metallurgical structure required for long life under shock and fatigue loads.

Before shipment every lot passes final visual, dimensional, and running checks at our QC facility. We confirm quantities, markings, packaging, and surface condition, then bundle mill certs, heat-treatment records, inspection reports, and dimensional data so you receive full traceability with the parts.
