What does roller center mean when talking about gravity conveyors?

Hello, I am John with A Plus Warehouse and I am here to answer your questions.

The roller center is the amount of distance in a frame between the center of the rollers.

The smaller a roll center may be means the smaller a box may be.

When loading boxes on the conveyor there must be a minimum of three rollers under the load at all times.
