Also known as induction heating power induction heater

Also known as induction heating Cross roller bearing induction heater, also known as induction heating equipment, all collectively work piece is heated both involve induction heating include: induction heating power supplies, induction heating equipment, bearing heater, bearing induction heater, including industrial after preheating induction heating power supply piping hot, Evaporation, copper brazing used, the basic working principle is to use alternating current generates an alternating magnetic field, the alternating magnetic field which is generated inside the metal conductor eddy (eddy current), heat rapidly so that the metal of the workpiece, in general, the heating effect, there is a frequency, a current, a magnetic field joint decision.
In induction heating, the temperature rise of the workpiece to be heated is a metal part, there will be induced heat the heater itself, most of the work to be induced through the use of cooling water to cool the heated portion of the workpiece is not a non-metallic heat .
All metal parts can be used induction heater to heat, such as cast iron, electrical short-circuit ring, car wheels, metal bars, pipes, bolts, screws large turbine, wind power blades slice, journal bearing, gears, pulleys, couplings, etc. .

Angular contact ball bearings

Angular contact ball journal bearing: 7000C-type (α = 15 °), 7000AC type (α = 25 °) and 7000B (α = 40 °) of several types. This kind of bearing lock port on the outer ring, the inner and outer rings can not be separated in general, can withstand radial and axial joint load and axial load in one direction. Axial load capacity from the contact angle, the contact angle is larger, the ability to withstand high axial loads. This kind of bearing can limit the axial displacement in one direction shaft or housing.
Higher speed limit contact ball bearings can support radial load and axial load can also be subject to pure axial load, axial load capacity by the contact angle and the contact angle increases with the increase.
