PTFE мягкой полосой кусты

This is composites material bronze wire mesh as frame and calendered with a film of filled poly tetrafluorethylene. This is of low friction and low wear,andin is rather soft and is to be applie readily by inserting between the two rubbing metal surfaces, and can fulfil the ideal aim of no noice,no lubricating,no maintenance and no pollution. At present,this is applied in those mechanical elements under relatively low load and low speed,such as in textile machines,spherical bearings,automobile door hinge and the operating rod for cars.
