Apparatus and preliminary testing for the experimental investigation of a steam lubricated journal bearing is described. The test bearing is an externally pressurized, double-row, orifice compensated type, 3.0 inches in diameter and 3.0 inches in length. The work is a continuation of a study of process fluid lubrication wherein the performance of a steam lubricated thrust bearing was previously investigated and reported AD-418 416. The work is directed toward the development of process fluid lubricated bearings for shipboard application. Steam was therefore considered to be the lubricant fluid with most potential for practical application. The choice of an externally pressurized test bearing, rather than a hydrodynamic type, was based on the load capacity requirements of probable shipboard applications. Preliminary tests were conducted at room temperature and at 400F using nitrogen instead of steam as lubricant. A base line of bearing performance was thus established for comparison with future performance with steam at various conditions. Author
