ASTM B439 - 00 Standard Specification for Iron Base Sintered Bearings (Oil Impregnated)

1. Scope

1.1 This specification covers sintered metal powder, oil-impregnated, bearings of four iron-base compositional grades:
Grades 1 and 2--iron-carbon
Grades 3 and 4--iron-copper

1.2 The values stated in inch-pound units are to be regarded as the standard. The metric equivalents of inch-pound units may be approximate.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
