The Impact of Coefficient of Friction on Polyurethane Drive Wheels

by | Oct 22, 2014 | 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...

Equipment Roller Customization

by | Aug 26, 2014 | Rollers

Sunray, Inc. is a leading polyurethane wheels and equipment roller parts specialist primarily because our main focus has always been extraordinary customer service. Making affordable one-of-a-kind custom feed rollers is just one of the many ways we cater to your individual needs. Equipment Roller Manufacturing Chemistry Polyurethane is a material with such amazing versatility that it is ideal for equipment roller manufacturing and customization. That’s because Sunray’s engineers can adjust the ingredient recipe for any of our industrial rollers to create exactly the shape, hardness, and resilience that you need for your own unique equipment roller applications and demands. We can, for example, modify the presence of particular polymers such as polyesters and polyethers to deliver targeted performance characteristics. Customizing High-Tech Conveyor Rollers You may want conveyor rollers designed for unusual conditions and industrial tasks but you aren’t sure where to find such rare conveyor belt rollers. Other poly rollers don’t meet your specifications. But Sunray is a solution-based manufacturer and our team can design and deliver conveyor rollers that are ideal for use in extreme heat or cold, water, and even environments where gamma-ray radiation is present or sparks are a hazard. Various Feed Roller Traits and Uses You may need a feed roller that has a particular elasticity, softness, or hardness but can also withstand intense friction and abrasion. You may want a pipe track roller that is solvent resistant to move industrial chemicals. Or you may require material handling rollers that meet FDA food grade criteria. Sunray can even customize low-vibration polyurethane rollers. So in addition to our vast inventory of standard urethane rollers we also...
