Nylatron™ GS PA66, is a Molybdenum Disulphide (MoS₂) filled nylon that offers outstanding strength and rigidity and a lower coefficient of linear thermal expansion than other nylon products. Due to these characteristics, Nylatron™ GS PA66 components maintain their fits and clearances and also have a reduced likelihood to seize as bearings. For these reasons, this grade is often used in bushings, bearings, roller wheels, pulleys, sheaves, wear pads, valve seats and seals throughout the construction and heavy equipment industries.
