JUNE 24, 1937. ADVERTISEMENTS. FLIGHT. 35 MADE IN ENCLAND Aircraft engines are often arranged with ?ushrods so inclined to the rocker arms as to impose upon the latter a certain amount of side thrust together with a tilting moment. Plain bearings usually prove unsatisfactory in such applications, giving rise to undue wear with consequent variation in valve lift. The special Timken tapered roller bearing shown in the small illustration has been developed expressly to meet these conditions This two-row pre-adjusted bearing resists loads from every direction, yet without increased play, friction or wear, and enabUs valve clearances and Eft to be held wilhin precise limits, maintaining power output and eliminating valve gear troubles. Ths L4 Jacobs 7-cylindsr radial eng'ns shown is so equipped and the attractive newcomer, the Amherst-Viliiers "MAYA" 4 cylinder inverted air-cooled inline Airmotor has all rocker arms mounted on Timken tapered roller bearings. British Timken Ltd. also manufacture a special light-weight range cf aircraft wheel bearings where radial and thrust loads are both met by the famous Timken tapered rollers. Their accumulated experience covers a wide field and they invite requests to collaborate in solving bearing problems. Amherst-Villiers photograph reproduced by courtesy of " Flight."
