PCMW264401.5E Imperial Thrust Washer 1.024x1.732x0.059 inch

PCMW-E Thrust Washers: Thrust washers of triple-layer PTFE composite material. Suitable for space-saving axial locating bearing arrangements. For slow rotational or oscillating movements. Initial lubrication not required. Maintenance-free.
PTFE E composite: PTFE composite bearings consist of a copperplated sheet steel backing on which a 0,2 to 0,4 mm thick porous layer of tin/bronze is sintered. By a rolling process, the pores of the sintered layer are filled with a mixture of PTFE (polytetrafluoroethylene) and molybdenum disulphide. An additional 5 to 30 mm thick running-in layer of the mixture is then applied to the sintered tin/bronze. This additional layer provides an optimum combination of the mechanical properties of the sintered tin/bronze and the good sliding and lubricating properties of the PTFE mixture. PTFE composite bearings have good dimensional stability and thermal conductivity.
