Couplings accommodate many bore sizes.

Press Release Summary:



Zero-Max CD® Couplings, with QD bushing hubs, are available in Single Flex and Double Flex models. Single Flex model provides misalignment up to 3° angular, 0.025 in. parallel and 0.160 in. axial. Double Flex model provides misalignment up to 3° angular, 0.089 in. parallel and 0.32 in. axial. Both are available with steel hubs to accept QD bushings in inch or metric bore sizes. CD couplings with QD bushing hubs are available in sizes 37 to 77.

Zero-Max CD® Couplings Available With QD Bushing Hubs
Allow One Coupling To Accommodate Many Bore Sizes

Plymouth, Minnesota: Zero-Max CD® Couplings, which combine the best features of both steel disc and elastomeric couplings, are now available with QD bushing hubs. Fast and easy to install, these standard QD hubs are designed to accommodate a large range of QD bushing bore sizes within one size CD Coupling. The QD bushings are available from local distributors in either metric or inch bores.

Considered to be the industry's most unique coupling innovation of the last decade, the patented CD® Coupling features a unique open arm disc pack design made of rugged composite material. The design provides the high misalignment capacity of elastomeric
couplings but with higher torsional stiffness.

The Zero-Max CD® Coupling also has higher misalignment capacity compared to steel disc couplings. It provides superior damping and isolation of shock and vibratory loads. This eliminates fretting corrosion and results in a dramatic reduction of stress fractures at the bolt hole locations, a common problem with conventional steel disc couplings.

The CD® Coupling also has excellent chemical and moisture resistance in hostile environments, conditions which are too difficult or impossible for steel disc and elastomeric couplings.

The new Zero-Max CD coupling with the QD bushing feature is available in both Single Flex and Double Flex models. The Single Flex model provides misalignment up to 30 angular, 0.025" parallel and 0.160" axial. The Double Flex model provides misalignment up to 30 angular, 0.089" parallel and 0.32" axial. Both models are available with steel hubs to accept QD bushings in inch or metric bore sizes. Currently these CD couplings with QD bushing hubs are available in sizes 37 to sizes 77 and are available in stock for immediate shipment from Zero-Max. The QD bushings can be purchased directly from most local distributors.
