Speed & Ratio Control

Fairchild speed control transmissions are totally enclosed mechanical variable ratio drives. As opposed to belt or traction drives, all Fairchild models are positive with zero slip. Some transmissions combine the variable speed unit with a mechanical differential to expand or compress the final speed range.

Position or Register Control

Fairchild Position or Register control transmissions are enclosed mechanical differentials designed to precisely control the angular phase relationship of mechanically connected rotating equipment. These differentials are used for dynamic synchronizing and timing of different machine elements.

Speed & Position / Register Control

Often an application does not fit exclusively into speed/ratio or position/register control. These special applications require simultaneously controlling the speed and position of the transmission output.
