Parts in Low-load Sliding Contact with an Abrasive Product

Parts in Low-Load Sliding Contact with an Abrasive Product (Ref 1) 

Many products are abrasive, either as a result of their basic structure and composition or through the action of added fillers or pigments. In low-load situations (as defined by the product areas discussed later in this section), the choice of surface treatment can be made primarily on the basis of surface hardness, since even very thin coatings are able to support the contact loads. 

The industrial areas covered in this section include textiles, printing, plastics, packaging, food, pharmaceuticals, leather goods paints, inks, ceramic powders, and wood processing. It is assumed that the part in question is in direct contact with the product (e.g., a textile guide, a print roller, a wood-cutting tool, a food chute, etc.) and not with another engineering component. 

The applications also cover seals, where a nonmetallic, for example, a filled polymer or elastomer, part is in sliding contact with a shaft or a thrust pad.
