PU tire casters are a popular wheel tread for use on industrial wheels, whether it is in a caster application or drive wheel applications.
1. Noise Reduction
Polyurethane tire casters are a popular choice in industrial applications because of their quietness in operation when compared to harder wheels such as steel or cast iron. The polyurethane acts as a shock absorber and helps to cushion the ride and absorb bumps from uneven terrain. The noise levels can be reduced dramatically when using polyurethane instead of steel or cast iron wheels, which can help protect your employees hearing.
2. Load Bearing Capability
Polyurethane tires are also often utilized for their load bearing capacity when compared to rubber. Polyurethane can provide a greater load bearing capacity while still providing the benefits of a rubber tread, such as noise reduction, shock absorption, and floor protection.
3. Coefficient of Friction
Another benefit to polyurethane tires in industrial applications is the coefficient of friction of the material. Polyurethane tends to be a grippy material and can help keep towed carts right-side up, where sliding can be a problem for harder wheel materials. It also provides good traction to drive wheels and helps to reduce the amount of load on the wheel to achieve the desired driving force.
4. Floor Protection
Polyurethane tires are also chosen in applications where floor protection is critical. The polyurethane will deflect and create a much larger footprint than harder wheel materials, such as nylon. This larger area helps reduce the stress concentration on floors and keep the floors in better shape for a longer period of time. So if your floors are expensive and critical to your operation, a polyurethane tire may be the correct choice for your application.
5. Resistance to Corrosion
There are many different types of polyurethanes that have varying levels of resistance to certain chemicals, solvents, or even water. In humid or wet environments, polyurethane can be chosen that will not break down or corrode in the presence of water. In other environments where chemical exposure is a problem, a different type of polyurethane can be used to prolong the life of the industrial caster.
