ABSTRACT:
A high precision, two-row ball bearing wherein the inner races of the two rows are worked into the shaft and there are respective outer rings around the rows of balls. A spacer bushing is axially disposed between the outer rings. The spacer bushing is of a single piece with an axial slot extending along its length. The slot has a width approximately equal to the diameter of the shaft. The center of the diameter of the bore of the spacer bushing is offset from the center point of the diameter of the external periphery of the spacer bushing, whereby the spacer bushing is radially thinnest opposite the axial slot and thickens toward the slot for balancing the mass of the spacer bushing with the material removed from the slot. A housing bushing surrounds the spacer bushing and the outer rings.
