There are many machines today; in particular, some aircraft in aviation also use bearings; today's aerospace bearings are of very good quality; today's bearings are also of good quality; especially the quality of imported bearings is very good; usually the bearings on the aircraft All of them use imported bearings; our domestic bearings still can't reach such quality specifications; no matter what the famous imported bearings are better than domestic bearings, the aircraft is related to the safety of life; therefore, the quality is used. The best bearing; today's imported bearing quality is the best. Especially the quality of SKF bearings is surprisingly good. Let's analyze the use of aviation, aircraft and helicopter bearings.
1. Trent900 and GP7000 engines
FAG is the only supplier of all jet engine bearings and many components of the new Rolls-Royce "Trent900" engine. The engine powers the Airbus A380, the world's largest passenger aircraft. FAG will supply the Airbus A380 in the future. The second generation engine, the GP7000 jointly developed with Pratt & Whitney and General Electric.
2. Trent500 engine
The FAG Aerospace Bearings team worked closely with Rolls-Royce; in a very short time; developed new spindle bearings in addition to the Trent500 engines for the Airbus A340-500 and A340-600 (highly integrated; using new information).
FAG's success factors: 1. The FAG aerospace bearing part is an important force for the development of engine bearings (spindle bearings and gearbox bearings). The Trent500 engine supplies extremely high power density.3. FAG's induction test bench test procedure demonstrates the reliability of high-strength spindle bearings.
3. The PW4000 engine exceeds half of the commercial passenger aircraft using Pratt & Whitney engines. Over 70 airlines are confident in the reliability of the PW4000 engine. The thrust is from 22 to 45 tons; almost all large aircraft are made by Airbus and Boeing.
Airbus: A300; A310; A330, Boeing: B747; B767; B777; MD-11
FAG's success factors: 1. The FAG Aerospace Bearings Division is the supplier of all spindle bearings for these engines. In addition; FAG Aerospace Bearings is the approved supplier of all gearbox bearings.3. The same; these bearings need to be satisfied with the highest quality and reliability specifications
4. BR700 engine
Integrated spindle bearings for the BR700 engine are equipped with: FAG Aerospace Bearings has developed spindle bearing assemblies for the BR700 engine. These engines were developed by Rolls-Royce (Rolls-Royce), Germany; used in feeders made by Boeing, Bombardier and Gulfstream. And business jets.
FAG's success factors: 1. "Synchronous Engineering Technology" and the user "hand in hand" for product development 2 . Through system integration; reduce product components and component quantities; save costs. Bearings and integrated spindle components are selected for electron beam welding.
5. Joint-intrusion-fighter
The FAG Aerospace Bearings Division is a new partner for new projects. For example, in the development of nozzle bearings for the VTOL (straight take-off and landing) joint attack aircraft (Lockheed system).
FAG's success factors: 1. VTOL system: Rolls Royce 2. Promote the system: Pratt & Whitney F135 / General Electric F1363. Nozzle bearing: diameter 1200mm, high temperature bearing ring, corrosion resistant steel, ceramic ball
6. SikorskyHelibusS92
Sikorsky helicopters use FAG roller bearings: FAG develops and manufactures many bearings for the Sikorsky Helibus S92 helicopter; the rotor uses active skewer bearings.
FAG's success factors: 1. Active and skewer bearings with higher power and reliability are depicted in 2. Double row of sheet bearings (diameter: 750mm), high corrosion resistant, fatigue resistant steel 3. Production of cylindrical roller bearings for helicopter transmission.
7. Space-propelled equipment turbo pump bearings: FAG Aerospace Bearings united with NASA (NASA) and Pratt & Whitney; developed bearings for the main engine of the space shuttle (liquid oxygen and hydrogen turbo pumps). Newly developed FAG bearings; Replace after each launch, can be used for repeated launches
FAG's success factors: 1. Years of experience in the field of aerospace engineering bearings 2 . Special information extends the bearing life by several times3. Ceramic balls and rollers 4. Nitrogen alloy; stainless steel bearing ring 5. Self-lubricating cage
8. Eurocopter
FAG's roller bearings are used on helicopters made by Eurocopter: many helicopters made by Eurocopter are equipped with FAG bearings.
FAG's success factors: 1. The integrated depiction allows the component to be significantly reduced. Optimize the internal structure; to add reliability 3. The coating protects the product from conflict corrosion4. Use wear-resistant and high-alloy data; extend bearing life.

Machine Screw

Non-tapping screws are machine Screw, the pieceworker to be fastened must be tapped with taps in the screw hole in advance to match the screw threads.

The difference between tooth screws and other screws depends on whether they can be used together with nuts. Tooth screws can be used with nuts. And relative to the screws of other teeth, there are self-tapping screws. The nut of this kind of screw has no bow teeth. As for the standard teeth and fine teeth are only different pitch, it is the nut of the machine screw
