Roller conveyors are more suited to heavier loads than skate wheel. It is commonly used for workstations and pick modules because it provides a better working surface and is often less expensive than skate wheel conveyor. It ‘s also good at slowing the inertia of products coming out of a high-speed sorter. Rollers are recommended for uneven, open, or rimmed bottom packages. They have spring-loaded axles for easy removal & replacement. Unlike skate wheel conveyors, the product should never be wider than the rollers.

Gravity skate wheel conveyors can only be used for packages with flat surfaces that do not have soft bottoms. Though there are several skate wheel patterns, there should always be a minimum of ten wheels under a box. The wheels can be made of galvanized aluminum, galvanized steel or even plastic.
