The gravity conveyor range made by Ultimation is among the simplest and most versatile types of conveyors. As a result, you can use gravity conveyor for either temporary or permanent installations. In addition, either permanent floor supports or temporary tripod style stands are available. While most rollers for gravity conveyor systems can range for 1-3/8″ diameter (1.4″) through 1.9″, you can also use 2.5″ and 3.5″ diameters for extreme duty applications. It’s easy to configure your own system and buy online. Or contact our staff and we will analyze your needs and configure it for you.
Ultimation Gravity Conveyor Combinations
Especially relevant is that Gravity Conveyor is ordered by specifying each one of these variables:
- Diameter of the rollers (standard diameters are 1.4″, 1.9″, 2.5″ and 3.5″). While larger rollers can carry more weight, they are more expensive
- Frame style (generally powder coated steel; aluminum frames and rollers available on some models). Generally steel is used unless light weight is very important
- Length of the conveyor. Choose from 5′, 8′ or 10′ sections for most conveyors
- Width of the conveyor. Width is generally measured as the distance between the two conveyor frames
- Spacing of the rollers (generally from 1-1/2″ apart, 3″, 4-1/2″ or 6″ apart). The is the center to center distance of the roller spacing
- Straight or curve configuration
How to choose and configure the right gravity conveyor:
- Choose the gravity conveyor width you need based on the product dimensions. Allow at least 1″ each side. Also consider wider widths or fixed or adjustable side guides (optional) if the product may move sideways on the conveyor as it moves
- Then decide on the length you need. Lengths of 5′, 10′ and curves can easily be joined together to achieve the layout required.
- Check the load rating table which shows the load capacity of each roller
- Next, decide on support centers for the conveyor legs if required. Support must be provide either at 5′, 8′ or 10′ intervals for all loads.
- Review the tables showing maximum “live” (moving) loads per foot that the conveyor frame is suitable for. Remember to count the maximum number of products on the conveyor at once
- Finally, make sure the product will move smoothly along the rollers and not get stuck between rollers. Therefore choose the roller center distance (2-1/4″, 3″, 4-1/2″ or 6″ between rollers) so that the product is always gliding on at least 3 rollers at the same time (more if the product is uneven on the lower surface)

Options for gravity conveyor
- Stationary floor support legs. Click here to see the available range (opens link in a new tab).
- “Rollers set low” (see graphic). Standard configuration of these conveyors is “Rollers set high” where the top of the roller is above the side of the conveyor frames. This is in case the side of the product being conveyed extends over the sides of the conveyor
- Guide rails – Adjustable channel guide rails, fixed angle and channel guide rails
- See the “Downloads” tab on this page for catalogs and more information
Skatewheel Gravity Conveyor
Skatewheel Gravity conveyor systems are just like gravity roller conveyors, except the rollers are “skatewheel” style rollers mounted on axles. This helps convey items with a flat bottom smoothly. They are generally more economical that gravity roller conveyors, but can handle lower load. Hence skatewheel Gravity conveyor components are available with steel or aluminum frames in many lengths and widths.
Gravity Conveyor Safety
- Never stand on or near gravity conveyors. Because of the low friction bearings, you will fall and may suffer serious injury
- Because heavy loads may move quickly and continue to accelerate, ensure that any decline sections are carefully configured and tested
- Be careful when creating systems where loads may create pinch points between the load and the rack or conveyor structure
