Abstract
471,154. Ball and roller bearings; lathe centres. ROTERBERG, W., (trading as PROZESKY, R., [Firm of]). Feb. 26, 1936, No. 5813. [Class 12 (i)] [Also in Group XXII] A lathe centre is mounted in a combined thrust and journal bearing comprising three individual bearing sets, the intermediate race rings being axially movable so that axial thrust is transmitted through them. The rollers a, b, c, run on races which either contact directly or have intermediate pieces d. Rollers may be replaced by balls, or combinations of balls and rollers may be used.
