Details:
Aligning ball bearings are two raceways in the inner and outer ring raceways between spherical , equipped with spherical ball bearings.
The outer ring raceway curvature center and bearing center line , and therefore have a self-aligning ball bearing with the same self-aligning feature. In the axis, deflection occurs when the shell can be automatically adjusted without increasing the burden bearing .
Aligning ball bearings with cylindrical bore and tapered bore two structures , and retainers made of steel sheet or synthetic resin. Which is characterized by the outer ring raceway spherical shape, with auto-Mind , can compensate for misalignment and shaft deflection aligning ball bearings into making errors , but the inner and outer rings relative inclination of not more than 3 degrees .

Material properties:
Pure ZrO2 is white, with yellow or gray impurities , generally contain HfO2, easily separated . The world's proven resources of approximately 19 million tons of zirconium oxide, zirconium is usually caused by zirconium ores purification system. At atmospheric pressure pure ZrO2 There are three crystal : monoclinic (Monoclinic) zirconia (m-ZrO2), Quartet (Tetragonal) zirconia (t-ZrO2) and cubic (Cubic) zirconia (c-ZrO2), the three crystal type exist in different temperature ranges , and can be transformed into each other .
