Polyurethane belts are commonly referred to as urethane belting, urethane belt, o-ring belts, round belt conveyor, o-ring belt, o-ring drive belt, lineshaft conveyor belt.

They are used in numerous applications. The most common application is in material handling equipment. These are lineshaft conveyors, roller to roller conveyors, pop up diverters, and transfer systems. Conveyor systems are found in large distribution centers and large manufacturers throughout the world. Besides in large distribution centers, polyurethane o rings are also commonly used in robotics, engravers, and many drive to pulley applications.

One of the most common problems is having the wrong size polyurethane belt on your application. If your polyurethane o ring or urethane belt is too small, it can pop and break or cause damage to your roller bearings. If the polyurethane o ring or urethane belt is too large it will slip and your boxes or material will not move down your line. If you are having a problem, give us a call and we can normally diagnose the problem over the phone with a few measurements. If not, we will gladly come out to your facility to perform a survey to make sure all your polyurethane belting is sized correctly.

Polyurethane belts or o-ring belts are ordered using the following specs:

  • Diameter- this is the thickness of the belt- anywhere from 1/8” to almost any thickness, most common in lineshaft conveyors and roller to roller conveyors is 3/16”
  • Durometer- this is the stiffness or hardness of the polyurethane or urethane- 60A-100A, 83A or 85A is the most common
  • Cut length- this is the actual cut length of the belt before it is welded together- This is what causes the majority of problems for customers. The 83A durometer polyurethane belt or o-ring belt stretches 10%-12%. So a polyurethane or urethane belt needs to be cut 10% to 12% shorter than the actual tape line measurement. Tape line measurement is the measurement using a string where the urethane belting or o-ring belt will actually run. This 10-12% stretch is usually true in lineshaft applications, roller to roller applications, pop up diverters and transfer belts.
  • Color or material of Polyurethane belt- The most common urethane belting is clear. It also comes in a translucent blue, a rough surface green, and an orange for thicker less stretching applications.
