Couplings resist hostile environments.

Press Release Summary:

CD Couplings include hub and bushing that have high chemical and moisture resistance in hostile environments. Hubs are precision machined steel. Couplings are available in Single Flex models, which provide misalignment up to 3 deg angular, 0.025 in. parallel, and 0.160 in. axial. Double Flex models provide misalignment up to 3 deg angular, 0.089 in. parallel, and 0.32 in. axial. Both models are available in sizes 37 through 77.

Original Press Release:

New Model Zero-Max CD® Coupling Accommodates Many Bore Sizes

Plymouth, Minnesota: Now Zero-Max CD® Couplings are more versatile than ever using the new QD hub and bushing model. That's because one size CD coupling can accommodate a large range of QD bushing bore sizes, making ordering, delivery and installation fast and easy.

Available in Single Flex models which provide misalignment up to 3 deg angular, 0.025" parallel and 0.160" axial, as well as Double Flex models providing misalignment up to 3 deg angular, 0.089" parallel and 0.32" axial.

The QD hubs are precision machined steel and are featured in the CD Coupling Single and Double Flex models from sizes 37 through 77. Standard QD bushings in either inch or metric bores are then mounted onto the QD hubs to complete the package. All coupling models feature a unique open arm disc pack design made of rugged composite material. This patented disc pack design provides the high misalignment capacity of elastomeric couplings but with higher torsional stiffness. The disc pack also has a higher misalignment capacity as compared to steel disc couplings and provides superior damping and isolation of shock and vibrating loads. The composite disc material eliminates fretting corrosion, a common problem with steel disc couplings, which can result in disc pack stress fractures at the bolt hole locations.

Another important feature -- CD® Couplings have high chemical and moisture resistance in hostile environments, conditions which are too difficult or impossible for steel disc and elastomeric couplings.

Single and Double Flex CD couplings with QD bushing hubs are available for immediate shipment from Zero-Max. (The QD bushings are purchased from your local distributor).
