oil resistance V-Belt are probably the only elastic belts that work well at hot temperatures above 200oF. Works up to 230oF (110oC). Our high temperature urethane belts are exceptionally strong, durable and long lasting, but relatively expensive. Available only as round belts. Natural* color. 90A durometer. Not weldable in the field. Do not stretch high temperature urethane belting more than 5%, as more stretch can cause it to fail prematurely. Recommended stretch is 4%.
Our High Temperature oil resistance V-Belt work well up to up to 170oF (77oC) and for moderate periods up to 200oF (93oC). They are much less expensive than our Ultra Hight Temperature Urethane belts and are weldable in the field. Tan color, 90A durometer. Do not overstretch during installation because polyester will not bounce back. Recommended stretch is 8%.
Each lot can vary in color from clear to tan to gold-tinted, yellowish or tea colored. Belts typically become more tea colored over time, but this does not significantly affect performance. Belts should not be exposed for long periods to sunlight or intense UV light, as this will degrade the material and cause a sever change in color -- usually deep yellow.
For the best in High Temperature Elastic Belting and Heat Resistant Belts for hot environments, insist on oil resistance V-Belt.
Each and every belt has a specific temperature range that it is not meant to exceed and that range is -18 degrees through 158 degrees Fahrenheit. What people often don't realize is that these are sustained temperatures. You could run your v-belts in consistently at 158 degrees and your belt would be able to withstand the abuse. You could do the same with the temperature being -18 degrees. If the constant temperatures exceed this mark, you run the risk of ruining the belt and in some cases the machine itself.
There are a five different types of v-belts that all have a different constant temperature ranges. The belt that has the lowest heat range is the standard v-belt. These belts are designed to work within the -18 through 158 temperature range. Raw edge belts on the other hand are capable of working under higher heat situations but don't handle the cold as well. Their temperature range is -1 degree through 212 degrees. This makes the the optimal belt for usage in higher heat applications. The reason that these belts are able to with stand higher heat is because they are cogged. The belt has had notches taken out of the underside of the belt to allow an increase in air flow.
oil resistance V-Belt means that the belt is oil and heat resistant. Many belt manufacturers are now making this the standard type of belt that is sent out because they are not much more expensive to make and the belt will last longer. They can handle a temperature range from -22 degrees through 212 degrees. A FRAS belt is a belt that is made to be Fire Resistant and Anti Static. This belt is designed so that if the belt is running in a place where a fire might be started by static shock, the belt will be a little more resistant. The temperature range for these belts are up to 275 degrees. The last belt only pertains to poly v-belts. These belts are made to withstand heats up to 302 degrees
The reason that these belts are priced higher and have a minimum order amount is because they are made out of natural rubber products. These are harder to get a hold of and when you do they are more expensive. Also, because there is less of a demand for these belts, the manufacturers do not want to be stuck with a belt that they can not sell. if you have any questions about high temperature resistance V-Belt, don't hesitate to ask.
