If your Delta 18-36 drum sander has stopped gripping boards or the conveyor belt is starting to fray, you are likely looking for a reliable replacement. I have analyzed these nine options to help you distinguish between specialized parts and entirely different machines. In my view, matching the correct replacement surface to your specific model is the most important step in restoring your shop efficiency. Here is an honest, ranked guide to your best options.
1. Drum Sander Feed Belt Conveyor Compatible with Delta 18-36 Drum Sander – 100 Grit Silicon Carbide, 18" x 47-1/2"
This belt earns its spot because of its 100 grit surface, which provides a consistent texture for general wood and plastic sanding. It is an excellent choice for owners who want a straightforward, durable replacement that matches the original factory specifications.
The bi-directional tape joint is a major benefit because it simplifies the installation process, allowing you to run the belt in either direction without worry. I appreciate how this design choice reduces the frustration often associated with alignment.
Buyers frequently confirm that this belt matches the dimensions for the 31-250 and 31-260X series.
The 18-inch width is widely regarded as a perfect fit for the standard drum setup.
Users often report that the silicon carbide material stands up well to regular sanding pressure.

2. 120 Mesh Drum Sander Conveyor Belt 18 x 47-1/2 Inch Fit for Delta
This belt is best for those focused on finer finishing work where a smoother, more controlled feed is required. If your projects involve hardwoods that require a delicate touch, the finer 120-mesh texture helps prevent unnecessary surface marring.
It is designed to increase friction, which is vital for maintaining transmission accuracy during smaller batch jobs. In my opinion, this belt is the most logical upgrade for anyone who finds their current feed is slipping on lighter materials.
Feedback highlights the ease of replacement as a major time-saver for busy woodworkers.
The increased surface grip is often noted as a key factor in reducing workpiece sliding.
Owners value the long-term stability this material provides compared to entry-level belts.

3. Drum Sander Feed Belt Conveyor for Delta 18-36 Drum Sander models 31-250 & 31-252, 18" x 47-1/2" by Monarch Industrial
An unexpected feature of this belt is its precise compatibility with service part number 655503-00, which makes it the standard choice for those performing routine maintenance. It functions exactly as the original manufacturer intended, ensuring your sander keeps moving without a hitch.
I consider this the top overall pick because it balances price, durability, and perfect compatibility. For anyone who treats their equipment like a long-term investment, this is the most reliable option for keeping a machine in peak condition.
Maintenance logs consistently suggest this part is the go-to for Delta 31-250 series owners.
Users praise the consistent 100 grit surface for its longevity.
The 47-1/2 inch circumference is frequently cited as the ideal fit for standard tensioning rollers.

4. 150 Grit Sandpaper Roll, 2 Inch x78.7 Feet Continuous Abrasive Sand Paper Ready to Cut Emery Cloth Roll for Drum Sander Woodworking Automotive Metal Sanding
The most common complaint about this roll is that it requires manual cutting and measuring, which can be tedious compared to a pre-sized belt. However, this limitation is also its biggest strength, as it allows you to adapt the abrasive to custom sanding needs across different machines.
I find the aluminum oxide material to be remarkably versatile for both wet and dry applications. If you do not mind a little extra prep work, this roll offers significantly more value than purchasing individual sheets.
Reviewers often point out that the anti-stretch material holds up well during high-pressure cycles.
Many users appreciate the ability to cut only what is needed to minimize waste.
The grit consistency is generally viewed as high quality for automotive and woodworking tasks.

5. JET 16" Drum Sander w/Stand, SandSmart Auto Feed Control (JWDS-1632)
When compared to the simple conveyor belts listed above, this product represents a massive leap into modern machine technology. While the belts are for maintenance, this unit is a complete replacement for those whose old Delta sander has reached the end of its life.
The SandSmart auto-feed control is a significant upgrade that prevents burning wood by adjusting the speed automatically. I would point most people toward this machine if they want to stop babysitting a dial and start prioritizing consistent output.
Owners regularly describe the dust collection system as highly effective for keeping the shop clean.
The toolless parallelism dial is frequently highlighted as a major improvement over older designs.
Assembly feedback indicates that the unit can be put together in under an hour.

6. VEVOR 22" Drum Sander with Stand & Extension Tables, 1.75HP 1440RPM Dual Motor Drum Sander for Woodworking – Variable Speed Conveyor Belt, 4" Dust Collection Port for Cabinet & Furniture Finishing
This machine became popular due to its large 22-inch capacity, which suggests it can handle wider boards than the standard 18-inch models. While it offers impressive specs on paper, it is a significant step up in weight and power compared to your classic Delta sander.
I believe this is a solid choice for those who need heavy duty sanding capacity for furniture or cabinet making. Just keep in mind that a machine this size demands a dedicated space in your workshop and a robust dust collection setup.
Users often report that the dual motor system provides reliable, consistent power.
The extension tables are frequently cited as a necessary feature for stabilizing large workpieces.
Many reviewers note that the variable speed control allows for great precision on different wood types.

7. Red Label Abrasives 1/2 X 18 Inch 36 Grit Aluminum Oxide Air File Sanding Belts, 20 Pack Sanding Paper Belts – Weld Removal, Metal Grinding, Woodworking, Knife Sharpening
The single biggest strength of these belts is the premium blue fired aluminum oxide coating, which stays cool even during aggressive metal grinding. They earn their ranking here because they handle heat much better than standard woodworking abrasives.
While these are not designed for your main conveyor, they are essential for weld removal and metal finishing tasks. I think these are a must-have for any multi-purpose shop that handles both wood and steel.
Buyers consistently praise the longevity of the abrasive under high-heat conditions.
The bi-directional tape joint is frequently described as a key feature for maximizing belt life.
Users report that the 36 grit is exceptionally effective for heavy stock removal on non-ferrous metals.

8. VEVOR Professional 4 x 36 in. Belt Sander with 8" Disc Sander, 5A Induction Motor Cast Aluminum Worktable for Woodworking, Metalworking
This tool is best for the benchtop shop user who needs a versatile, space-saving unit rather than a dedicated wide-belt sander. It combines two types of sanding into one footprint, making it ideal for smaller shops that handle a mix of woodworking and metal finishing.
The 5-amp induction motor is quieter and more reliable than the standard hobby motors found on similar benchtop tools. While it lacks the wide-surface capability of an 18-36 sander, it is a high-value utility machine for general shop chores.
Owners frequently comment on the stability provided by the cast aluminum worktable.
The ability to tilt the sanding belt up to 90 degrees is often listed as a major design benefit.
Reviewers appreciate the inclusion of a dust port for keeping the workspace relatively tidy.

9. DELTA 18 x 36 Drum Sander 31-250 Instructions & Parts Manual
An unexpected feature of this manual is the inclusion of detailed exploded-view diagrams, which are invaluable when you are trying to identify a broken spring or a missing screw. It is more than just a set of instructions; it is the definitive guide for anyone attempting a deep repair on their machine.
I recommend keeping this manual close by if you own a legacy Delta sander. It is the best way to ensure you are ordering the right parts and following the correct safety procedures for your Delta 18-36 equipment.
Users often note that the diagrams make identifying part numbers much faster.

Choosing Between Them
My top recommendation is the Monarch Industrial feed belt because it is specifically engineered for your Delta 18-36 models, providing the exact fit and durability required for consistent shop performance. If you need fine finishing, the 120 mesh conveyor belt is an excellent alternative, while those needing a total machine upgrade should look at the JET 16-32 drum sander. For specialized metal work or benchtop utility, the Red Label belts and the VEVOR combo sander offer the specific capabilities those tasks demand.
Always keep in mind that maintaining a drum sander requires consistent attention to belt tracking and tension regardless of the brand you choose. Regularly checking your machine for dust buildup and ensuring the conveyor surface is clean will significantly extend the life of your equipment. Taking these small steps will ensure your sanding results stay professional for years to come.
