 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.
Features:
- Two ball rail systems mounted at 90 degrees and an angled carriage: higher stiffness and load capacities
- camoLINE connectivity: easy, precise connection and alignment of additional axes to the carriage of the Bridge Modules
- Aluminum cover and polyurethane sealing strips: protection from contamination
- Standard connecting brackets for Rexroth's other linear modules MKR, MKK, CKR, CKK: simple construction of mult-axis systems
Benefits:- Higher torsional stiffness reduces deflection for higher load and moment capacities
- BKK (ball screw driven version) features ball screw supports for high speeds at longer lengths
- Simpler mounting and assembly than using two modules in parallel
