Organization: ASTM
Publication Date: 10 November 2000
Status: inactive
Page Count: 6
ICS Code (Bearings in general): 21.100.01
scope:

This specification covers sintered bronze, oil-impregnated bearings made primarily from elemental copper, tin, and graphite powders. The manufacturer may, at his discretion, use prealloyed bronze powder in the blend.

This specification covers the following variables:

Grades - Available in three bronze base composition grades identifiable by different graphite contents.

Type - Grades 1 and 2 are available in four types described by specific density ranges.

Bearings ordered to this specification will normally be sized after sintering and will be impregnated with a lubricating oil unless otherwise specified by print.

The values stated in either inch-pound or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
