A roller for a conveyor system is comprised of a body portion that is generally cylindrical and rotatable about a central axis. A first bearing surface is defined around the body portion. A second bearing surface is raised above the first bearing surface and is generally concentric to the first bearing surface, the second bearing surface being more resilient than the first bearing surface.

Self-adjusting conveyor system

A conveyor system for conveying a basket or rack through a chamber having a system for stopping a rack at a predetermined location along the conveyor. The system is comprised of a rocker device mounted relative to the chamber. The rocker device has a first normal position wherein the rocker device is movable from the first normal position when the rack engages the rocker device. The rocker device has an upper arm and a lower arm. The rocker device is rotatable about an axis disposed between the upper arm and the lower arm. A magnet is disposed on the lower arm of the rocker device. A sensing element is aligned with the magnet when the rocker device is in the first normal position. The sensing element is operable to provide a signal to a system controller. A stop is mounted relative to the chamber. The stop is rotatable from a first position to a second position. The stop has a tab dimensioned to engage the rack in the conveyor system when the stop is in the first position. The tab does not engage the rack when the stop is in the second position. A means of actuating the stop is movably connected to the stop. The means is operable to move the stop between the first position and the second position. The system controller is operable to control the means of actuating based on a signal from the sensing element.
