Abstract: A glass fiber web and a wet lay process of making the glass fiber web. The glass fibers of the web include glass fibers sized with a sizing composition which includes a partially amidated polyalkylene imine cationic lubricant randomly dispersed in a cured thermosetting resin. The wet lay process includes the steps of so sizing the glass fibers followed by separating such fibers by immersing the glass fibers in an aqueous dispersant medium to form an aqueous dispersion which is agitated. The separated sized glass fibers are dried. The dried, sized glass fibers are then bound with the thermosetting resin binder. The curing of the binder produces the product glass fiber web.

Abstract: A rolling element bearing, comprises an inner ring, an outer ring and rolling elements which are in rolling contact with the raceways of the inner ring and the outer ring. The rolling elements and/or the raceway (2) of at least one of the rings is coated with a metal-mixed diamond-like carbon layer (8).
