2nd major advancement in Rubber Bearings... (our Contour Design was 1st) THREE YEARS OF ACTUAL SERVICE HAS PROVEN -THESE ADVANTAGES ARE YOURS ONLY WITH m 'DEMOUNTABLE L SERIES' STAVE BEARINGS HEAVY DUTY COMMERCIAL SERVICE Write for literature on ? Demountable Stave Bearings ? Principle of "Steady Flow" lubrication ? Complete line of Stuffing Boxes 1. Multi-durometer 'Precision Fitted' solid rubber stave bearings. 2. Improved shaft alignment found only in a precision fitted bearing. 3. Improved 'Steady Flow' lubrication. 4. 'Reduced' mechanical vibration. 5. 'Suppression' of resonance vibration. 6. Bearing staves are self-locking within the housing under tons of compressive force. 7. Ease of shaft installation and withdrawal with bearing in place. 8. Housing bore is always 'straight', never stepped. 9. 'All' journals the same size throughout the shafting system. 10. V3 the cost of conventional bearings through elimina-tion of nonessential brass shell. 11. Replacement of bearing in VA the normal time without removal of shaft or propeller. Only Johnson offers these and many more advantages. "WORLD LEADER IN MARINE BEARING RESEARCH" JOHNSON RUBBER COMPANY MARINE DIVISION MIDDLEFIELD, OHIO 44062 ? AREA CODE 216-632-2)11 May 1, 1969 23
