Learn how to pick the right conveyor sanding feed belt for your drum sander. We cover sizing, joint strength, and grit to keep your sander running smoothly.
Quick answer
Measure your drum sander's conveyor belt dimensions exactly, then match the belt's joint type and grit to your workload. Red Label Abrasives offers heavy-duty aluminum oxide belts with a no-bump tape joint that fits most JET Performax, SuperMax, and Delta models.
Why belt dimensions must be exact
A conveyor feed belt that is even a fraction of an inch off will not track properly, causing uneven sanding or belt damage. Measure the length and width of your existing belt or consult your sander's manual. For example, the JET Performax SuperMax 37 uses a 35 x 67 1/2 inch belt, while the Delta 18-36 uses an 18 x 47 1/2 inch belt. Ordering the correct size is the first and most critical step.
Joint type matters for durability
The joint is the weakest point on any belt. A bi-directional, no-bump tape joint, like the one used on all Red Label Abrasives conveyor belts, prevents the belt from snagging or leaving marks on your workpiece. It also resists stretching and breaking, so you get consistent performance over the life of the belt.
Grit selection for your material
Coarser grits (36-60) remove material fast for initial shaping or heavy stock removal. Medium grits (80-120) are for general smoothing. Fine grits (150-220) prepare surfaces for finishing. Match the grit to the stage of your project. If you are unsure, start with a medium grit and adjust from there.
Decision rules for choosing a conveyor sanding feed belt
- Measure your belt: Remove the old belt and measure its length and width. Write down the exact dimensions. If the belt is worn, check your sander's manual for the correct size.
- Match the joint type: Choose a belt with a bi-directional, no-bump tape joint. This prevents snags and marks on your workpiece and extends belt life. A no-bump joint is especially important for finish sanding where surface quality matters.
- Select the right grit: Use coarse grit (36-60) for heavy stock removal, medium grit (80-120) for smoothing, and fine grit (150-220) for final finishing. Buy a few grits to cover different stages of your project.
- Verify your sander model: Check the model number of your drum sander. Many belts are model-specific. For example, the JET Performax 16-32 (new model JWDS-1632) uses a 17 1/4 x 38 inch belt. Always confirm the model number before ordering to avoid returns.
