Magneto bearing applications
Magneto bearings need to understand the situation, you need to first understand Magneto. Magneto is the use of a small permanent magnet alternator generates a magnetic field, a gasoline engine ignition system ignition power, they use a rotating magnetic motor magnet structure, according to the overall design can be divided into single type and flywheel. Magneto during operation will produce a spring-like compression resistance, so will cause axial load bearing from unilaterally when magneto ignition device during operation, will produce some current transmitted through contact with Magneto to this current will cause some bearing itself galvanic corrosion, and environmental impact with the magnetic field of the impact of the bearing is self-evident, so the requirement is magneto bearings can bear certain axial load, and has a certain resistance to electrical resistance.
Magneto bearings are separable 15 ° of angular contact ball design, the inner ring - ball - holder assembly as a whole, using the wrap-holder made of high quality precision bearings hardened bearing steel.
