40、for Table I: (1) Cast bimetal on steel, bronze or brass back. (2) Maximum of 0.60% lead is permissible, providing a lead-tin solder has been used for bonding the bearing alloy to the backing material. (3) These materials are available as cast or sintered bearings with identical chemistry. They are u
41、sed interchangeably unless the suffix ”C” (cast) or ”S” (sintered) is added to the alloy designation. For example: BL-26-10C, CL-4S. (4) Lining will have a Rockwell hardness of 68 HRE minimum, unless otherwise specified. (5) Not to be used for new applications. (6) These materials are supplied with
42、overplate added to the bimetal material to make trimetal bearings. Overplate designation and thickness must be included on drawing. (7) Tin content may be raised to 1.25% maximum upon agreement between purchaser and supplier. (8) Obsolete material. Supplier will contact appropriate engineering depar
43、tment when drawing specifies this material. (9) Current Navistar spec designation reflects current MPIF STD 35 in which suffix denotes radial crush strength.

Materials Engineering and the supplier should be consulted before specifying hardness values on the drawing. 4.3.2 P/M Materi
47、als Unless otherwise designated on the drawing, P/M bearing material properties will meet the minimum values specified in MPIF Standard 35. These values include strength constant, porosity or oil content, and density. 4.3.3 Radial Crushing Force The theoretical radial crushing force of a bearing is
48、a function of the “K” strength constant and its dimensions. Radial crushing force will be calculated as indicated by the equation below. (NOTE: This equation is not valid when the wall thickness is greater than 30% of outside diameter.)
