These companies can provide surface coating fluids containing particles to increase the coefficient of friction i.e. coefficient of friction to 0,25 to 0,3. (ref links 1 below) The American Gear Manufactures Association (AGMA) recommends a value of between 0,12-0,15 for hydraulically expanded hubs and 0,15-0,20 for shrink or press fit hubs.
For decades, it was widely believed the Americans with Disabilities Act (ADA) required a static coefficient of friction (dry or wet as applicable) of 0.60 or higher for level floors and 0.80 for ramps. In fact, this was never true, and the Access Board of the U.S. Department of Justice has disavowed any responsibility for this custom.
Product Description. The term lagging describes the variety of elastomers used to coat the contact surface of a conveyor pulley. Its primary purpose is to enhance traction by increasing the coefficient of friction between the surfaces. The enhanced friction may also improve belt life by allowing lower belt tensions and reducing abrasive ...

For a flat belt, the maximum value for (T_2) will depend on the value of (T_1), the static coefficient of friction between the belt and the surface, and the contact …
Figure 6.10 Frictional forces, such as [latex] overset{to }{f}, [/latex] always oppose motion or attempted motion between objects in contact. Friction arises in part because of the roughness of the surfaces in contact, as seen in the expanded view. For the object to move, it must rise to where the peaks of the top surface can skip along the bottom surface.
