Inspecting Since 1955

Bearing Inspection, Inc. was founded in Huntington Park, California.

Born as a result of aviation turning to jet turbines, Bii was founded just 3 years after the first commercial jet airliner began operation. The company was originally founded as a bearing inspection facility and would not begin repair until 1960.

Bii Develops Level 2 Reconditioning Process

Bii is commonly acknowledged as the founder of the modern-day reconditioning process for turbine jet and other critical use turbine engine bearings. This process has the advantage of providing maximum savings to the customer while bringing the bearing back to the functional equivalent of new.

Bii obtains FAA Repair Certification for All Anti-Friction Aircraft Bearings.

FAA approval for all aircraft engine bearings validates Bii's bearing reconditioning approach and opens the way to the future success of bearing repair as a mainstay of Bii's business.

Extending Bearing Lifetimes

Our aerospace bearing reconditioning process returns your bearings to a like-new operational condition without sacrificing the quality, safety, or service life of your bearings. In fact, 80% of the bearings we receive are candidates for repair or overhaul. Based on bearing endurance data collected by NASA, approximately 92% of bearing sets that are available for refurbishing, result in a lifetime equaling or exceeding the predicted life of a new bearing.
