DODGE 015780 RAPTOR 70HCB 3-5/16" COUPLINGS/FLEX CLUTCH

A better choice has arrived

Coupling maintenance and reliability should not consume your maintenance team's time. The Dodge Raptor elastomeric coupling is the answer to these concerns. The Raptor’s easy to assemble, patented split natural rubber element significantly decreases total costs of ownership and extends driven equipment life. Built for drop-in interchangeability, the Raptor features an innovative design offering easier installation, reduced maintenance, and improved reliability in a wide range of new and existing applications.

Superior natural rubber element

Leveraging over 50 years of Dodge’s natural rubber expertise, the Raptor features a natural rubber flexible element that offers a number of performance benefits when compared to competitive urethane designs.

• Industry leading misalignment capabilities
• Less vibration transmission to connected equipment
• Better shock absorbing capabilities
• Static conductive for grounding redundancy, allowing current to safely pass through the natural rubber element, preventing the possibility of arcing during operation
• Exceptional resistance to hydrolysis, for improved performance in humid environments
• Superior thermal conductivity and ability to dissipate heat and hysteresis build up

Patented WingLock™ element design

Dodge Raptor utilizes a patented finite-element optimized winged elastomeric element design. This WingLock technology increases surface area in the most critical regions of the element, resulting in higher bond strength, improved fatigue resistance, and longer life versus competitive designs.

Documented performance

Comparative benchmark testing confirms the performance improvements associated with Raptor’s WingLock element design. Even under worst-case misalignment and torque conditions, testing results show that Raptor lasts six times longer than the closest competitor. Results based on accelerated life testing at 1.5x cataloged torque, while subject to 4° angular misalignment and 3/16” (4.8mm) parallel misalignment.

A practical solution to spacer couplings

The innovation behind the Raptor coupling also extends to applications requiring additional space between shaft ends.

• One spacer element fits all standard ANSI and ISO spacer lengths.
• Spacer elements can be replaced with standard closecoupled elements, resulting in lower replacement costs and reduced inventory.
• Eliminates the need for high-speed rings, resulting in easier installation, while also reducing purchase costs and inventory requirements.
• Modular full spacer design can be converted for use in half spacer and close-coupled applications, providing opportunity for inventory consolidation

Armored elements for extra protection in harsh environments

Raptor couplings are available with an optional armored element. This allows users to benefit from the increased performance and longer driven equipment life of standard Raptor elements, while providing an added layer of protection from ozone, petroleum oils, and some chemical environments. Raptor armored elements exceed ASTM 1149-07 rubber deterioration standards, as determined through third-party testing.

Improved features, easier installation

The Dodge Raptor has everything needed for easier installations and reduced maintenance costs.

• Split element for easy replacement without moving and realigning connected equipment
• Slotted clamp ring holes offer 187% extra mounting hardware clearance versus competitor’s circular through holes.
• Approximately 50% lower torsional stiffness makes the element significantly easier to manipulate by hand during installation.
• Maintenance free non-lubricated natural rubber element for trouble-free operation
