The variator belt is designed to offer great variability in terms of speed and power. In fact, it offers infinitely variable speed control. They are generally made of fiber-reinforced rubber, which gives them great strength and flexibility for operation under varying speed and load conditions. It's this variability that makes variator belts so useful for applications such as pumps, fans, compressors, tractors, combines and seed drills.
The variator belt is therefore often used in industry and agriculture. They ensure a smooth, jolt-free transmission. This optimizes energy efficiency and ensures adequate performance.
As the variator belt is subject to wear, it should be inspected regularly and replaced if necessary. The exact interval depends on the type of equipment used, and its operating conditions. It's always best to consult a qualified mechanic or dealer to determine the correct timing for drive belt replacement.
There are two main types of drive belts:
Whether ISO or DIN variator belts, they both have a large number of sections (height x width) and several lengths. At 123Bearing, for this type of product, we mainly offer the OPTIBELT, CONTITECH and DUNLOP brands. These brands offer high-quality drive belts, designed for long-lasting performance and reliability.
When choosing the right variator belt for your equipment, it's important to take into account the original part number or dimensions. If you have the original part number, simply enter it in the search bar on our website to find and order it. If you don't have this reference, you'll need to take the cross-section of your belt and its inside length. For the cross-section, i.e. the height and width of your belt, we invite you to use a caliper to be as precise as possible. For length, you can use a special belt-measuring ruler (called a MESSLAT) or a tape measure.
Overall, the choice of any drive belt is based on these two methods: reference identification and/or dimensions. If in doubt, it's best to consult a qualified mechanic or dealer to ensure you get the right drive belt for your needs.
We stock a wide range of sizes and brands, so you can be sure of finding the perfect belt for your application. With 123Bearing, you'll get the best quality at unbeatable prices. As always, don't hesitate to contact us if you have any queries or concerns about your drive belt choice.
