Conveyor Concepts, Inc. is a distributor of high-quality polyurethane belting. Conveyor belting varies from conveyor to conveyor, and our experts know the perfect solution for you. There are many different names for these endless round belts such as round belting, O-ring belts, or endless drive belts. When installing or modifying conveyor systems conveyor belting is a key to discovering the correct solution to handle your product. While there are many things to consider in the process of selecting the correct belt, it is important to know the three variables: durometer, length and color. Utilizing knowledge of these three variables belts can be selected to drive product with enough force and durability.
O-Ring durometer is the hardness of selected drive belt. Durometer is important because it determines the driving force of the conveyor system. While lighter strength belts are easier to replace, they have a lower driving force. A low driving force works fine for many scenarios when conveyor product is not very heavy. However, when heavy product is placed on a conveyor it will require a higher drive force, in these scenarios we recommend a high tension conveyor O-ring. A denser durometer on a conveyor drive belt will also be more resilient to damage from products traveling over the conveyor O-rings while in use. While in use there are a multitude of reasons for a belt to wear out, which is why we always carry spare conveyor O-rings and spare conveyor drive belts on our shelves. The different durometers available are: 60A, 70A, 75A, 76A, 80A, 83A, 85A, 88A, 90A, 92A, 95A, 100A, and 53D.
Next is the cross section of a conveyor O-ring, which is the thickness of a given belt. For example, the standard O-ring for line shaft conveyor is 3/16” x 13.50” O-ring 83A. Since this configuration of a drive belt has a twist, the thickness is lower to allow for the proper stretch of the O-ring. The cross-section of a conveyor O-ring can vary from 1/16” all the way up to ¾”. While durometer plays a role in the strength of a belt, so does the thickness. The thicker a conveyor drive belt the more resilient and powerful the drive belt will be.
Finally is the length of the conveyor drive belt, which is critical to order the correct length to fit the custom conveyor system that needs spare conveyor O-rings. The general length can be found by cutting an O-ring in half; however, these O-rings stretch over time and that could lead to an inaccurate measure of O-ring length. When a new conveyor system is installed, it is best to buy additional spare parts, including spare conveyor drive belts. By keeping new spare parts on hand, it is possible to get an accurate reading of what replacement conveyor parts are needed before they are damaged or altered. The length varies depending on centers between rollers, line shaft conveyor, between rollers in the curves, and depth of the groves in pulleys or rollers.
