Standard Spider for Spidex® Coupling

Quick-Flex flexible urethane coupling inserts are resistant to most chemicals and available in four materials for varying temperature and torque needs:

Quick-Flex red insert (standard)
The standard Quick-Flex red insert is made from a relatively soft urethane compound. This insert is well suited for a wide range of applications. The standard insert excels in vibration dampening and cushioning of shock loads and is best for reversing applications or applications with quick starting and stopping of high-inertial loads.

Quick-Flex blue insert (high torque)
The Quick-Flex blue insert is made from a relatively stiff urethane compound. This insert is well suited for applications with moderate to high torque. Quick-Flex couplings with the blue insert deliver high torque while maintaining a degree of torsional softness and the ability to dampen vibration. They are excellent replacements for gear, grid or chain-style couplings.

Quick-Flex white insert (high temperature)
The Quick-Flex white insert is made of a heat-resistant urethane compound for use in applications where heat is a concern. This insert can handle temperatures up to 177° C and provides torque capabilities equal to our blue insert.

Quick-Flex black insert (highest torque)
The Quick-Flex black insert offers the highest torque ratings of all inserts. This insert is well suited for very high torque applications, and Quick-Flex couplings with a black insert are excellent replacements for gear-style couplings. When using a high-speed cover, the use of a black insert is not recommended. In an application where high torque is present, use a split-cover option.
