Quick-Flex® Elastomeric Couplings

The Simplicity of Quick-Flex Couplings Beats Other Coupling Designs

A Quick-Flex coupling, consisting of two coupling hubs, elastomeric insert and cover, offers advantages not offered by other coupling designs such as jaw, grid, gear, chain, tire or disc couplings.

Quick-Flex couplings are direct replacements for virtually all comparably sized couplings in use. Quick-Flex couplings require no lubrication and are easy to install and maintain. Once the two coupling hubs, insert and cover are installed for the first time, the coupling hubs do not need to be moved again for the life of the equipment. The straight-forward design means there is no possible interference between the coupling hubs if the insert fails. Plus, the urethane insert can be easily changed without moving the hubs or shafts.

Lower your maintenance costs with one of the most rugged coupling designs available for a wide range of applications today.

Quick-Flex Benefits

• Never needs lubrication
• Easy to replace urethane insert without moving hubs
• High torque ratings (up to 1,670,825 in-lbs)
• Shaft sizes from 1/2” to 11-1/4”
• Hubs not damaged by insert failure
• High speed capacity (up to 5,000 RPM)
• Fewer loose pieces
• Shock loads absorbed while accepting misalignment up to 20,000 horsepower
• Compact
• Lower cost

Choose from four inserts for varying torque needs and temperature ranges up to 350 F (177 C). Extend shaft separation 1” to 120” by ordering standard and double-ended spacer couplings. Stainless steel versions are available for harsh and food processing environments. Select standard covers for high RPM applications and split covers for high torque applications.
