Tandem sub for a roller bearing

Abstract

Description

FIG. 1 is a first perspective view of a tandem sub, showing our new design.

FIG. 2 is second perspective view of the tandem sub of FIG. 1, shown from a different angle, and from an end opposite that of FIG. 1.

FIG. 3 is a top plan view thereof.

FIG. 4 is a bottom plan view thereof.

FIG. 5 is a right side elevation view thereof.

FIG. 6 is a left side elevation view thereof.

FIG. 7 is a front plan view of the tandem sub of FIG. 1.

FIG. 8 is a rear plan view thereof.

FIG. 9 is a cross-sectional view of the tandem sub of FIG. 1, taken across Line 9-9 of FIG. 8, and showing a bore of the tandem sub. Because the bore is cylindrical, all views of the bore (top view, bottom view, left side view, and right side view) will be identical; and,

FIG. 10 is a third perspective view of the tandem sub of FIG. 1, with a roller bearing shown in exploded apart relation to demonstrate environment.

The broken lines in the drawings depict portions of the tandem sub for a roller bearing that form no part of the claimed designs.
