Superior Bands focuses on quality Polyurethane O-rings. We start with unused Polycord, no regrinds or fillers. We focus on a strong weld on our O-ring drive bands. It is very important as your Polyurethane O-rings undergo stress when running conveyors continuosly. A poor weld will not hold up to the daily operations of a distribution center.
The next step in manufacturing Polyurethane O-Rings is the sanding off of the excess or flash. When the Polyurethane O-ring cord is heated on both sides and welded together it creates extra polyurethane when it is welded together. This extra “flash” or polyurethane has to be removed. Here is where we see another problem with inferior polyurethane o-rings. This is a common problem we see, when someone over sands the poly o-ring, it creates a serious defect that over just a little time, the poly o-ring will fail and break apart. When part of the weld is oversanded it removes part of the structural integrity. This oversanding causes the Polyurethane O-ring to come apart and fail.
The other thing that separates us from other sellers of Polyurethane O-rings, is us. We are a second generation American Manufacturer, and we stand behind our products. We are not just punching a clock, this is what we do. If you ever have a problem, we are here to help you work through it, even if it is a misorder or mismeasurement.
Running a factory or distribution center is a difficult task. It is not easy. We know, we have been manufacturing since 1954. We don’t have restocking fees or RMA Paperwork. We fix the problem, the easiest and simplest way. If you call us, you are usually speaking with the owner, or someone that has been here over twenty years.

What are Polyurethane O-rings?
Polyurethane O-rings, also known as polyurethane, urethane, O-ring belts, or O-ring drive belts are the industry standard for most motor pulley to shaft applications. These mostly include conveyor systems in large distribution centers. Poly O-rings are used as a driving factor on many different machines, including, but not limited to: line shaft conveyors, robotics, engravers, roller-to-roller conveyors and transfers, pop-up diverters, sorters, laundry machines, tire manufacturing, and printing machines. There are three common methods to determine the O-ring size you need.
Method One: Cut Length (Measuring of Prewelded/Endless Polyurethane)
Method Two: Application Measurement (Measuring of Conveyor Line Shaft)
Method Three: From a Twisted O-Ring Length
