BZA

The BZA heavy-duty toothed arc coupling from R+W Couplings is designed to span longer distances and transmit high torques. This industrial coupling features a compact corrosion-resistant design, high power density, and is very low in clearance and maintenance. Additionally, the element can accommodate significant lateral, axial, and angular misalignments. For specific inquiries about toothed arc couplings or other industrial couplings, please contact VARIODRIVE.
