The Global Leader in Tungsten Disulfide (WS2) coating Micro Surface is the global leader in Tungsten Disulfide (WS2) coating and for over 30 years has applied it to the AMS2530 & DOD-L-85645 standards and lead the way with its use in a variety of applications. With a thickness of only 1/2 micron and an operating temperature of up to 1,200°F it is an excellent coating to reduce friction and noise without needing to resize components. MSC recently completed an initial round of testing on bearings coated with WS2 and a standard stock set which showed the Tungsten Disulfide (WS2) coated bearings lasted much longer and endured more rigorous testing conditions than the uncoated bearings while requiring a significantly lower level of torque and ran at a lower operating temperature.
