The GB straightening roll series complete with axle is designed to guide and straighten material being processed thru straighteners in demanding applications, and can be used in other applications and devices. The straightening rolls can be re-greased and are prepared for resisting high speeds and high loads. As an option, alternative roll materials or specific coatings can be realized. Roll axle assemblies in the GB series are available in many sizes to suit a variety of straighteners and other applications. They are available with both “V” grooves as well as “U” grooves. On a custom basis, other types of profiles are also possible. This high quality and robust German quality designed roller/axle is suited for wire applications but also is used for tubing, cable and other materials.
