Abstract
An adjustable height self-lubricating pulley system for use on the flyer bow of a twisting machine that twists strands. The height of the pulley can be adjusted to control the distance of the cable from the flyer bow during the cable's path along the flyer bow by selectively mounting the pulley spindle in one of a plurality of apertures in a pair of side plates of the pulley. The pulley is self-lubricating by virtue of the pulley spindle being coated with a self-lubricating liner system including polytetrafluoroethylene and other fillers in a resin system.
