Linear Modules and Cartesian Systems BKK Bridge Modules Bridge Modules feature an extruded aluminum profile whose geometry has been optimized for extremely high torsional stiffness. Inside, two internal ball rail systems are mounted at a 90 degree angle to each other to maximize load and moment capacity. The Bridge Modules are ideal for applications where the module is not fully supported, such as the Y axis in a gantry system. It can also span long lengths unsupported.
