Description:

Claim:

Our invention relates to ball bearings, especially adapted for heavy supporting duty, for instance, in metal working machinery, and we have instanced its use in a radial drilling machine, and utilized for supporting the rotatable column which has the drill-arm thereon.

In a radial drilling machine the column is a heavy body, usually in the form of a sleeve received about a post. It carries the drill-arm thereon, and the drill-arm has a. usual tool-slide thereon, the tool-slide being laterally adjustable on the arm, and the arm and tool-slide usually supporting the driving means for rotating the drill spindle and feeding the same axially, many of the parts in practice being mounted on the slide and sliding back and forth on the arm with the slide toward and from the column.
