Waukesha Bearings Identifies

Worldwide Marine Service

Now ship propulsion system service is al- most as near as a local telephone call any- where in the world. A brochure, identifying a worldwide marine service group, has just been released by Waukesha Bearing's Corporation.

Companies comprising this world network, known as Waukesha Marine International, are

Waukesha Lips B V of Drunen, Holland;

Chuetsu-Waukesha Co. Ltd. of Tokyo, Japan, and Waukesha Bearings Corporation. The brochure touches briefly on each company in terms of its capabilities, and also includes tele- phone and index dire'etories of 24 se'rvice offices spanning the United States, Canada, Europe,

Japan, and Southeast Asia.

A second brochure, Catalog W-4A, is a fully descriptive and illustrated brochure on line shaft bearings for shi'p propulsion systems.

Treated within the literature are three dif- ferent types of bearings—self-aligning, non- aligning and journal—as well as lubrication systems that include ring, disc, and forced oil methods. Also covered are detailed dimensions for ail shaft sizes from 14 inches to 36 inches in diameter.

For a copy of the brochures or further in- formation, contact Eric A. Dow, Waukesha

Bearings Corporation, Box 798, Waukesha,

Wis. 53186.

Newport iNews Shipbuilding and Dry Dock

Company, co-authors, presented a paper on "Main Propulsion Shafting Eccentricity Con- siderations."

Mr. Harrington holds a BME degree from

North Carolina State University, a master's degree in naval architecture and marine engi- neering from the University of Michigan, and an MB'A degree from William and Mary. Mr.

S. Fielding

R.P. Pike C. Hanson

Their paper described existing criteria to es- tablish eccentricity tolerances on propulsion shafting and concluded that many of the re- quired tolerances for naval shafting are unnec- essarily restrictive, whereas those specified for merchant vessels are not sufficiently restrictive to assure satisfactory performance. Cost crite- ria for establishing tolerances and methods available for straightening propulsion shafting were included in this excellent paper.

Discussers were S. Fielding, formerly with the Maritime Administration ;l J. Toohey, Beth- lehem Steel Corporation; R.P. Pike, National

Forge; C. Hanson, U.S. Steel, and R. Yohe,

American Bureau of Shipping.
