Quality Inspection and Verification Services

Two certifications power Alpine’s quality inspection and verification: ISO 9001 and AS9100D. As a result, our quality management system is compliant with some of the highest standards in the aerospace industry.

Because of our certifications, we only accept bearings from manufacturers who themselves align with the same certifications. We maintain the same stringent quality standards from incoming receipt and inspection through packing and shipping.  Through our certifications’ repeatable work instructions, we minimize variation, creating the ultimate consistency for maximum quality. We perform first-article and pre-shipment verification inspections to the AS9100D standard, inspecting high percentages of product to AQL level 7. We survey our customers to confirm that our bearings arrive at the quality standard you expect and perform perfectly for their expected lifespan.

Alpine employs bearing experts with extensive metrology training, who are qualified to inspect and verify quality to the American Bearing Manufacturers Association (ABMA) or International Standards Organization (ISO) standards your organization requires. Dimensions and characteristics we can verify for ball and roller bearings include:

  • Running accuracy, including digital noise, roughness and torque
  • Boundary dimensions and internal clearances, including radius and roundness
