AEFA has skilled product planning engineer team and R&D team. Our commitment to continually mix and advance technology and engineering permits U.S. to optimize bearing planning solutions that offer a competitive advantage for our customers.
We are developing following generation of setting friendly merchandise like low torsion bearings to cut back energy consumption. These bearings are employed in thousands of different merchandise.
They are available associate in a very} large vary of various sizes: from a miniature bearing with an inner diameter of four millimeter employed in ultra-compact motors, through to a control employed in big boring machines that dig tunnels.
Long life and high durability bearings
Bearing life and responsibility comparison take a look at on AEFA bearings and a widely known complete bearing. Place the 2 brands of bearings on the skilled bearing life strengthen take a look ater (ABLT-3) for the comparison test. As shown within the figure left, set 1KN of radial load and 500N of axial load, and operate endlessly for a thousand hours at 15000RPM.
AEFA bearing rings and steel balls square measure “zero-wear”, as follow figures
Selecting appropriate lubricants is additionally a vicinity of the great support. we've developed our own vary of rolling bearing greases from a spread of lubricants. The greases square measure tested with progressive testing procedures and systems. They provide very good conditions for long bearing operational life and operational safety.
High temperature bearings
AEFA’s high-temperature greases consist of thermally stable, preferably synthetic base oils incorporating organic or inorganic thickeners. For lifetime lubrication, however, AEFA recommends operating temperatures which are considerably lower in order to achieve acceptable running times
Low-temperature greases
Lubricting greases exhibiting minimal consistency increase at low temperatures provide excellent low-temperature stability. Suitable base oils for low-temperature duty are synthetic esters, PFPE oils and polyalphaolefins.
High speed bearings
Bearing life and reliability comparison test on AEFA bearings and a well-known brand bearings. When a bearing operates under load, heat is generated internally as a result of rolling, sliding and fluid friction.
In order to regulate temperature rise at high speed, AEFA technology center in turn did experiments and analysis on dozens of grease that square measure provided by world famed oil makers, finally set many of foreign grease that square measure best suited for electrical power tools characteristics and needs.
Their comprehensive performance at high speed is extremely smart, particularly for lower temperature rise and higher life performance. General makers solely live the temperature of bearing outside diameter that is pseudoscientific.
Bearing surface temperature is just 40°C, whereas the bearing internal and grease temperature has reached 130°C. AEFA has taken the result in treat bearing within most temperature as a live of the temperature indicator.
Once the surroundings temperature is 25°C, the rotating speed is 18000RPM, AEFA bearing and a widely known complete bearing run 2 hours underneath a similar axial load of 100N, we have a tendency to compare the bearing highest temperature measured by the thermal infrared imager.
