BoWex couplings are designed to transmit torque between drive and driven components via curved tooth hubs and a nylon sleeve. The combination of these components provides a torsionally stiff connection and accommodation for misalignments. This product is available in materials and elements that are optimized for close coupled applications. BoWex couplings, suitable for horizontal or vertical applications, are constructed from a variety of materials providing a torsionally stiff platform optimizing the balance between coupling performance and application requirements. The double‑crowned tooth reduces edge loading while accommodating misalignments and transmitting torque. The symmetrical relationship of the hubs and floating nylon sleeve allows for minimal maintenance in a close coupled design.
