Bearings for Sulzer Slow‐Speed Diesel Engines

In a paper to the Institute of Marine Engineers in London on 14th November, Dr. P. E. A. Borgeaud (Technical Director, Diesel Engine Department, Sulzer Brothers Ltd., Winterthur) presented some detailed developments in the RND range of Sulzer slow‐speed Diesel engines which, a few years ago superseded the RD series. The main difference in the new range was in the super‐charging arrangement: pulse system for RD and constant pressure system for RND. Service experiences have caused various refinements and improvements, and in connection with bearings, the author had this to say.
