These rollers are utilized in industries such as woodworking, newspaper and print industries, plastic fabrications, medical equipment and material handling (conveyor systems). Whatever your application may be, finding the right roller manufacturer that specializes in the type of roller you are looking for, whether it is an impact roller or a form of urethane roller, is the difference between a good product and a great product.
Impact rollers are in place in order to assist conveyor belt systems in handling their loads in an efficient manner. Guide rollers are in place to protect objects that are on conveyor systems or to assist products such as drawers, doors, fences, and other similar applications in keeping alignment while it is in motion. While urethane rollers that are utilized in the print world are in place to press ink onto paper in a uniform manner. All of these application are very different, which means that there are a lot of specialty manufacturers out there who have years of experience working with each specific style of roller.
A guide roller would not be able to function within an impact roller application as they have a different diameter of shell and typically have a thinner rubber layer, where an impact roller has a smaller core diameter with a large layer of rubber to help absorb the impact. The opposite is also true; an impact roller would not function well within an application meant for a guide roller.
