Thrust washers are not technically washers. Thrust washers are bearings
that happen to look like washers. A thrust washer is a flat bearing that
sandwiches in between a rotating component and a stationary component
and acts to keep the rotating component in place by giving it something to brush up against if it starts to move sideways. We machine thrust washers from Nylon MD (MOS2) rod or plate stock, which is more heavy duty than molded plastic thrust washers. Normally, thurst washers diameters are twice the shaft diameter.
Molybdenum disulphide (MoS2) filled nylon offers improved strength and rigidity. With a lower coefficient of linear thermal expansion than nylon natural. Nylon MD parts maintain better fit and clearances, and have less tendency to seize as bearings.
Custom thurst washers are machined various MOS2 Nylons such as: Nylon MD, Nylatron® GS, Nylatron® GSM, Vekton®, Nylon 6/6 MDS, and more.
