Fabricast grade FAG180 is the low noise level grade used for all standard assemblies. In general, a noise level of approximately 1 microvolt for each milliampere of current flow can be accomplished depending on the speed of the unit and quantity of brushes per ring.
Fabricast grade FAG150 is the highest surface speed grade: however, noise levels are slightly higher than FAG180. Brush life is approximately twice that of FAG180. It is recommended when brush life is critical and/or surface speed is high. Low noise can be achieved with multiple contacts per ring.
Fabricast grade FAG193 has highest current carrying capacity; however, it is limited to a surface speed of 250 ft. per minute.
Fabricast grades FAG180A and FAG150A contain molybdenum disulfide in addition to silver and graphite. This additive is required for operation in altitude, vacuum, and inert environments. Other characteristics remain the same.
