Polyurethane wheel casters have tremendous advantages over all other types of casters. Whether they are intended for home use, commercial or industrial applications, the careful consumer will find that these casters have benefits in both use and economy. Here are just a few of the good reasons to consider wheel casters with polyurethane covers for the next purchase.
Polyurethane casters tend to be quiet. The slightly rubbery texture of polyurethane does not transmit or amplify sound easily, which reduces noise substantially when the casters are in motion.
Polyurethane casters put less wear and tear on surfaces. Metal casters can be nearly indestructible, but they simply are not suitable for any sort of softer surface. Even a low pile carpet can be irreparably damaged by one piece of heavy equipment moved across it on metal casters. If there is even the slightest possibility that the equipment may someday have to cross a vulnerable surface, then polyurethane casters are a far better choice than metal.
On the other hand, polyurethane casters are far more durable than most of the other casters recommended for soft surfaces. Rubber might have approximately the same qualities of shock absorption and floor protection as polyurethane can, but it does not have nearly the same characteristics of strength or length of service. Polyurethane casters have nearly the same load bearing capacity as metal casters would. The tread is only millimeters thick, but it has been bonded to the iron core of the caster with a chemical process that renders it nearly impossible to remove. Sudden failure is not a problem with these polyurethane casters.
Polyurethane is also nearly impervious to corrosion and environmental degradation. It can be fully immersed in water for months without any damage to the caster surface. Industrial equipment in toxic or challenging environments can certainly benefit from being placed on polyurethane casters, especially if the equipment is expected to remain in that situation for a long time. It is also possible to order special types of polyurethane casters designed for exceptionally hot or cold environments, but it is difficult to imagine working environments that commonly exceed the tolerances that the ordinary casters are designed for. The standard temperature ranges these casters have been rated for was listed as between -40F to 180F.
Polyurethane casters have a rugged and tactile nature. They tend to grip the surface that they travel across and hold their position with great ease, which is a major advantage that metal casters cannot offer.
If no other options are chosen by the customer, the standard color for these casters will be green resin around black metal. However, these casters are available in literally any color imaginable. There are no limits to the color combinations with polyurethane. Polyurethane is the only common caster surface that can make that claim while still offering a combination of reliability and economy.
There are many more special applications of polyurethane that can be accessed as well. Because polyurethane is a synthetic polymer, it can be manufactured to nearly any specification. For example, if a customer decides they need a low-grip red-tinted surface that is designed to resist humidity and outdoor exposure, then casters can be created with exactly those characteristics. It may also be less expensive than the customer might be expected.
