Significance and Use
5.3 The desired self-lubricating performance of PM bearings requires a minimum amount of interconnected porosity and satisfactory oil impregnation of the interconnected porosity. A minimum oil content is specified.
1.2 With the exception of the values for density and the mass used to determine density, for which the use of the gram per cubic centimetre (g/cm3) and gram (g) units is the long-standing industry practice, the values in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
