Common Belt Failures in Aggregate Equipment

Hard-working aggregate screeners, like the Cedar Rapids model, use a tensioner idler pulley that presses against the back of the v-belt. Standard v-belts simply aren’t designed for that—and yet, for years, people just accepted the fact that their belts would fail every couple of months.

But not every belt failure can be blamed on poor design. Often, the root cause is simply age or neglect. Belts that sit too long without being replaced can dry out or harden, reducing their effectiveness and increasing the chance of snapping under load. Worn-out sheaves are another frequent culprit—if the groove is too shallow or misshapen, it can cause slippage or improper belt tension. Sometimes the belt is just the most visible failure point, and the real problem lies elsewhere in the system.

Fast Response, Fast Shipping, and Troubleshooting

In an industry where downtime can cost thousands per hour, availability is everything. Most end users don’t stock belts—they rely on suppliers to have what they need, when they need it. When a belt fails under load or due to a worn sheave, it’s an emergency.

That’s where D&D shines. They help troubleshoot in the field and get those high-demand belts shipped the same day 98% of the time.

Support That Helps You Win Business

For equipment dealers and resellers, working with D&D means more than just ordering parts. It means winning trust.

At Power Equipment Company, we switched to D&D about two-and-a-half years ago because our field guys were asking for better belts. Since then, we’ve had fewer complaints and better performance. D&D's pricing and inventory availability helped us win deals we might have lost otherwise.

Even better? D&D stocks odd sizes you can’t find anywhere else—and if you need a banded belt cut down, they’ll make it happen.

Equal to the Best. Better Than the Rest.

Compared to the industry’s top legacy belt manufacturers, D&D meets or exceeds them all in performance and support. They’re open to innovation, fast to respond, and willing to work with you when there’s a challenge in the field.
