What Is A Mind-adjusting Ball Bearing?

The center-ordination ball bearing is a bearing with a ball ball between the inner ring of the two raceways and the outer ring of the raceway for the sphere. The curvature center of the outer ring roller face is consistent with the bearing center, so it has the same adjustment function as the auto-adjusting ball bearing. When the shaft and housing are flexed, it can be adjusted automatically without increasing the bearing burden. The center-adjusting roller bearings can withstand radial loads and axial loads in both directions. The radial load capacity is large, which is suitable for heavy load and impact load. The inner inner diameter is a bearing of the conical hole and can be installed directly. Or use a tight set, removal barrel mounted on the cylinder shaft. The cage uses a steel plate stamping cage, a polyamide forming cage and a copper alloy car frame.

The center-centered ball bearing has two structures, cylindrical hole and conical hole, and the material of the cage has steel plate, synthetic resin and so on. Its characteristic is that the outer ring raceway is spherical, with automatic centeradjustment, can compensate for the difference of heart and shaft deflection to create the error of the heart-adjusting ball bearing, but its internal and outer ring relative tilt must not exceed 3 degrees.

It can withstand large radial loads, but also a certain axial loads. The outer ring raceway of this type of bearing is spherical, so it has the adjustment performance, when the shaft force bends or tilts so that the center line of the inner ring and the center line of the outer ring are tilted relatively by no more than 1 degree to 2.5 degrees, the bearing can still operate.

The inner holes of the centering ball bearing sither cylindrical and conical. The cone-shaped inner hole has a cone of 1:1 2 or 1:30. In order to enhance the lubrication performance of the bearing, the ring oil tank and three oil holes are processed on the outer ring of the bearing.
