Standard Parts
Most manufacturers will use special motors, valves, or controls so that nobody else can use them. When you need parts and/or service, there is only one place to get them, and that is the original manufacturer of the appliance.

Stainless Steel
The US Commerce Department defines a "Durable Good" as a manufactured item, such as a car or an appliance that typically lasts at least 3 years. The Pizza industry is approximately 40 years old and has used conveyor ovens only in the last 20 years.

Stainless Steel vs. Aluminized Steel
Aluminized steel is similar to galvanized steel. Both are carbon steel sheets that have a thin layer of either aluminum or zinc applied to the surface to protect against rust. Most other oven manufacturers use aluminized steel for the interior and back of their ovens.

Bearings
We have rebuilt hundreds of Lincoln and Middleby Marshall ovens. The conveyor bearings we have seen are 1/2", 5/8", or 3/4" in diameter. Of the 1/2" bearings, we have seen about a 90% failure rate. The 5/8" bearings experience about a 50% failure rate. We have not seen a failure yet on a ¾" bearing.

Fuses
Fuses protect components. Airplanes and other high quality goods are designed so that a failure of one component will not disable another component. For example, if a motor "shorts out", it could damage the control that is driving it if there is not a fuse between them.

Clean-ability
The entire front panel comes off in seconds with just 4 stainless steel knobs, no tools required. The fingers come out the front even faster.
