What is the recommended method for replacing a properly sized belt?

The recommended method for replacing a properly sized belt is to use the Rubber Manufacturers Number (RMA). This standard provides specific guidelines for determining the correct belt size, ensuring compatibility with the drive system and its operational requirements. RMA guidelines help technicians select belts that meet the necessary specifications for load capacity, length, width, and other critical factors, which contributes to optimal performance and longevity of the belt.

Utilizing the RMA ensures that the correct belt is chosen based on industry standards, which reduces the risk of using an improperly sized or unsuitable belt that could lead to operational inefficiencies or premature failure. By following this method, it is easier to find a replacement that fits well and functions correctly within the existing machinery.

In contrast, simply measuring the old belt length might not be sufficient since the belt may have stretched or worn over time, leading to incorrect replacement. Increasing belt tension is generally not a method for replacement—it might temporarily address slippage but can lead to premature wear or even damage. Choosing the first available size without adequate consideration could easily result in selecting a belt that does not fit correctly, compromising system performance and reliability.
