Abstract
The present disclosure relates to a low friction bearing liner for a solenoid may include a low friction layer. The low friction layer may include a first fluoropolymer matrix component and a first thermoplastic filler component distributed throughout the first fluoropolymer matrix component. The content of the first fluoropolymer matrix component may be at least about 1 wt. % and not greater than about 99 wt. % for a total weight of the first low friction layer. The content of the first thermoplastic filler component may be at least about 1 wt. % and not greater than about 99 wt. % for a total weight of the first low friction layer.
