The Impact of Coefficient of Friction on Polyurethane Drive Wheels

There are always forces at work around us, whether working for us or against us. One of the predominant forces in the world of polyurethane drive wheels is the co-efficient of friction (COF). In layman’s terms, the co-efficient of friction (COF) is the amount of resistance an object encounters when moving over another. For example, when a polyurethane drive wheel is used to turn a conveyor belt, the wheel must overcome the friction exerted on it by the belt to spin. Most of the wear and tear experienced by the belt and the polyurethane drive wheel will be the result of this friction. Another example of co-efficient of friction is when a polyurethane wheel rolls over a surface, such as a concrete floor. If the wheel must roll over contaminants, such as debris or pits in the floor, it will require a greater coefficient of friction to keep the wheel moving. Likewise, if the floor is finished and polished, the co-efficient of friction will be less. Companies that specialize in providing skid- or slip-resistant surfaces will often measure the coefficient of friction (COF) to determine the degree of slip resistance of a surface. The higher the coefficient of friction, the greater the slip resistance, and the harder an object will have to work to pass over it. The coefficient of friction is always measured as a value between 0 and 1. When measured from a resting position, for example the friction between a conveyor belt and polyurethane drive wheel when the belt is not in motion, it is a measurement of “static coefficient of friction” (SCOF). When measured in...
