Ordering a Dorner Conveyor? This 7-Step Checklist Came From Real Mistakes

I've been ordering Dorner conveyors for production-line integrations since 2017—mostly the 2200 Series, with belt widths from a few inches up to 24 inches. I'm not a conveyor engineer, and I'm definitely not here to deliver a lecture on mechanics. I'm the person who places the order and then has to explain why an expensive piece of the line doesn't fit, doesn't run, or doesn't move the product the way everyone expected.

How expensive? I track my own mistakes. Roughly $11,000 in wrong belts, reordered mounts, expedited replacements, and pure scrap can be traced back to things this checklist now catches. I should add that most of that damage happened before 2023. Since I started actually working through this list, we've caught about 40 small and large issues before they became invoices.

Use this when you're sitting in front of Dorner's configurator or about to send a PO for a Dorner conveyor system. It applies to replacement conveyors, new lines, and one-off test stands. The whole thing takes about 20 minutes.

One quick note before the steps: this matters even for small orders. I've seen a two-foot conveyor get far less review than a 40-foot line. That is exactly backwards. A short conveyor that jams or misroutes product can stop the same production line as a long one, and the downtime doesn't care what you paid for the conveyor.

1. Choose the belt type before you choose the speed

"Standard belt" is a trap. There is no universal belt that works for every product, every angle, and every environment. A smooth belt that handles cardboard totes on a flat section may not handle machined steel parts on a slight incline. The reverse is also true—a grip belt can create unnecessary friction and wear if the product slides across it at a merge point.

I once specified a 2200 Series conveyor with the default belt for a line carrying aluminum brackets. On the horizontal section it was fine. On the short incline to the next station, the brackets slid backwards and jammed the guard. The reorder cost me about $800 and a week of waiting. Not a catastrophic number, but it was pure waste—the right belt had been one option away in the configurator.

Ask yourself what the product is made of, whether the conveyor runs on an incline or decline, and whether liquids, oils, or dust are present. If you don't know which belt surface is right, ask the application engineer before you buy. The configurator will happily sell you the wrong belt; it has no way of knowing your product is slippery.

2. Measure the installed footprint, not just the belt path

The length between pulley centers is not the same as the space you need on the plant floor. Actually—no, wait—the conveyor frame itself is rarely the surprise. The parts bolted to it are: the gearmotor, the motor bracket, cable guards, controls, and sometimes the tensioning hardware at the idle end.

I've made this mistake in a tight line layout. The conveyor length was correct, but the gearmotor stuck out into an aisle that was supposed to stay clear for forklift traffic. We had to rotate the whole motor arrangement after installation, which meant new brackets and another round of electrical work. Nothing in the conveyor drawings was wrong—I just didn't look at the full assembly view.

When you download the dimensional drawing from the configurator, check every dimension that extends beyond the frame. Don't measure from the belt path and call it done.

3. Read the configurator output like a purchase contract

This is the step that sounds obvious and gets skipped most often. A Dorner conveyor part number is not just an SKU. It encodes real decisions—belt width, belt type, drive configuration, motor voltage, and other options. If you don't know what each part of the model number means, you are ordering a machine with an unread label.

I'm not going to pretend I memorized their part number convention. I ask the Dorner representative or my distributor to walk me through it at least once per project. On one order, the model number looked fine to me, but the belt type code was different from the previous identical setup because the configurator had quietly changed the default. It probably shouldn't have—don't hold me to this—but that kind of change is exactly why you read the full output before approving.

If you're using the Dorner configurator, export the PDF and read the item description line by line. It takes two minutes and it catches slips that are easy to miss in a storefront-style interface.

4. Nail down the gearmotor side before it's cast in metal

Drive location is one of those details that gets decided by default, then becomes painful later. The gearmotor can usually be mounted on either side of the conveyor, but "either side" doesn't mean you can swap it in the field without cost.

The conventional wisdom is to put the motor on the side closest to the controls or the electrical panel. That's not always right. Maintenance access matters more. If the motor is against a wall, against another conveyor, or under a guard, every inspection becomes a contortion trick.

Think about direction of product flow when you define left and right. It's easy to mirror the orientation in a CAD view and order the wrong drive side. I've caught two of those by physically standing where the operator will stand and asking: "Which side do I want someone to work on?"

5. Leave room to tension and change the belt

This is probably the most overlooked item on the list. New conveyors don't need much attention, so it's tempting to install them tightly against guarding, a wall, or a machine frame. But belts stretch, tracking drifts, and eventually you need to reach the tensioning adjustment or remove the belt entirely.

A few years ago, we tucked a small Dorner conveyor into a custom frame with almost no clearance at the idle end. It worked perfectly for about eight months. Then the belt needed replacement, and we discovered the only way to get it off was to unbolt the conveyor from the structure. What should have been a 40-minute job turned into most of a day.

The clearance doesn't need to be huge—sometimes six inches is enough. But check the manual's recommended service access instead of assuming. I should add that if you're designing guarding around the conveyor, design it so the guard can move out of the way, not just "open for inspection." Access for hands is not the same as access for a belt.

6. Don't guess voltage, phase, or VFD compatibility

Electrical specs are the least glamorous part of ordering a conveyor, and they cause some of the longest delays. A gearmotor that runs on the wrong voltage or the wrong phase isn't going to self-correct. It's going to sit on the floor while someone figures out what to do next.

Check the motor nameplate requirements against the actual supply available at the installation point. "The plant has 480V" may be true in one area and false at the specific location where the conveyor will run. If you're using a variable frequency drive, make sure the motor is rated for inverter duty—small AC motors sometimes aren't, and the results can be noisy, hot, and unreliable.

I'm not 100% sure how many times this has caused problems for other people, but I've personally dealt with two situations where the conveyor arrived and the motor was simply the wrong electrical configuration for the line. Both were avoidable with one email to the supplier.

7. File the configuration before the box arrives

This is my favorite step because it costs nothing and saves time for years. When the order is placed, save three things: the configurator PDF, the sales order confirmation, and a screenshot of the final product page. Put them in a folder that belongs to the machine or the line, not in your personal email inbox.

A year later, when someone asks for a replacement belt or a spare gearmotor, you'll have the exact specification without measuring the conveyor again. We've used ours four or five times for reorders. Honestly, if I had done this from the beginning, I would have avoided at least one wrong replacement part order.

Oh, and one more thing: if the conveyor is being bought as part of a larger system, share that folder with the maintenance team before installation. They're the ones who will eventually need the details.

A few notes from the field

First, the size of the order doesn't change the discipline. The supplier that pays attention to a one-unit conveyor order is worth remembering. When a larger project comes along, that's often the best place to start—not because they're big, but because they treat small questions seriously.

Second, lead times shift. I can't quote a current number with confidence—it varies with component availability and the season. Ask for the promised date in writing and build in a buffer if the conveyor is tied to an installation deadline. The value of a promised date isn't just planning; it's the ability to escalate when something changes.

None of these steps will make you look like a hero. They are unglamorous checks that don't appear on a project schedule. But they're the difference between a smooth startup and an afternoon spent explaining why a small mistake is holding up a whole line. If you've ever signed off on a conveyor order, you know exactly what I mean.
