Advantages of the one-piece design compared to the conventional two-piece guide wheels (wheels with separate bushing or journals) include lower profile and increased rigidity, larger diameter fasteners, less tolerance stack-up, external adjustment and tightening, and lower procurement and installation costs. DualVee wheels come in carbon-steel, stainless steel, and polymer-overmolded stainlesssteel construction.
