Aircraft Bearings - Pictorial Introduction



Ultra-Precision High-Value Bearings


Bearings

Bearings are everywhere! ... bicycles, trains, windmills, helicopters, cranes, elevators, ships, dentist-drills, rockets, and many more – bearings carry the load, and keep turning.

Invented by Leonardo da-Vinci 500 years ago, billions of bearings are made each year in each continent. However, not all bearings are created equal...

Bearings and Aircraft

High-value bearings are found in aircraft engines and other aircraft systems. A typical passenger jet may include 100 to 175 high-value bearings, with total value of $300,000 to $600,000 of bearings per aircraft.

Airbus (Europe) and Boeing (USA) deliver an estimated 100 new aircraft each month, or over 1,000 per year. Other companies deliver a significantly larger number of military jets, commuter-aircraft, executive jets and helicopters worldwide.

Most passenger jets have two engines. Others, such as the Airbus 380 and Boeing 747 have four engines. Each such aircraft has an Auxiliary Power Unit and other systems with high-value bearings.

High-Value bearings may cost from $2,500 to over $50,000 per bearing. The installed population of all aircraft bearings worldwide may be close to $50 Billion.

Commercial aviation worldwide has an established growth of 5% to 7% per year, and is estimated to remain above 4% for the foreseeable future.

The world's top bearing manufacturers, Timken (USA), SKF (Sweden), FAG (Germany), and NTN (Japan) sell new bearings and provide bearing overhaul services for aircraft engines, and seek additional revenue from the sale of replacement bearings.

Aircraft and Maintenance

Aircraft maintenance is predictable, periodic, and mandatory by law. Maintenance is done to precise specifications and regulated by the aviation authorities (FAA, EASA).

Industry reports estimate the global aircraft-maintenance business to exceeds $45 Billion per year, excluding Military aircraft, with aircraft engines making up 43% of the global aircraft maintenance business.

According to Aviation Week's data published in January 2013, Airlines globally are expected to spend $17 Billion on Engine Shop visit (Engine Repair and Overhaul) in 2013 with similar forecast for 2014 and 2015.

Since the 70's Aircraft maintenance has been an international business with no boarders, for reasons related to the nature of aviation, government programs, military offset programs, and high-tech innovations in aircraft maintenance technologies.

Bearings and Aircraft-Maintenance

Maintenance of specialized aircraft components is generally outsourced to specialized “Approved Repair Station” companies worldwide. Each such company works under strict oversight of the FAA (USA), EASA (Europe), CAAC (China), and other local authorities.

There are almost 5,000 "Approved Repair Station" companies worldwide, tending to every part of the aircraft from alternators to auto-pilots, and from windows to wheels. The majority of these “Repair Stations” have fewer than 100 employees, are low-cost, and compete with the larger "OEM's” (manufacturers) on providing specialized repair and overhaul of aircraft parts.

100% of all high-value bearings are inspected during each aircraft overhaul, and approximately 30% to 40% of bearings are rejected.

By repairing the rejected bearings, typical savings of over $100,000 can be realized during each overhaul. These savings are significant for airlines operating dozens or hundreds of aircraft, with several aircraft undergoing overhaul at any given time.

These same savings represent lost revenue-opportunities to the bearing OEMs (manufacturers), as the repaired bearings displace the purchase of a new bearing.

Bearing Inspection and Repair

Each repaired bearing must meet or exceed the performance specifications of a new bearing, and is subject to 100% inspection by specialized personnel and equipment.

The records of each person, equipment, process, and date when each bearing was cleaned, inspected, and repaired are kept for a minimum of 3 years.

Each repaired bearing is approved to "return to service" only after individual inspection and acceptance by an experienced professional licenced by the FAA.
