Roller guides can be made to cover complete range of guide sizes for all different shapes and steel grades. These days the design of the roller guides needs the manufacturing and assembly of a reduced number of parts without compromising any feature which is expected from a quality roller guide. This also makes the assembly process a lot quicker.
