ATCoat-coated rolling bearings

ATCoat-coated rolling bearings provide an alternative to bearings made of stainless steel, achieving comparable corrosion behavior, particularly on the functional surfaces. The layer thickness of 2-4 μm with a dome-shaped surface structure exhibits excellent properties under extreme conditions. Especially in conjunction with ceramic rolling elements, the ATCoat coating enables significant increases in speed at lower operating temperatures. Furthermore, the prevention of fitting rust on free bearings, which occurs due to the micro-displacement of the outer rings of the rolling bearings during thermal expansion or vibration, often allows for a considerably longer, trouble-free operation of the units. The special topography of the surface significantly improves the emergency running properties of the rolling bearings. For example, in the event of a lubrication system failure, the units can continue to operate under partial load for a certain period of time or function properly...
