Overview
The Dodge PX40 T-L Para-Flex coupling is an elastomeric tire-type flexible coupling designed for industrial motion control and power transmission applications. The coupling features a patented cording that transmits torque, offers a wear indicator, and absorbs shock loads to prevent damage to connected equipment. The split element design enables easy installation and includes industry leading misalignment capabilities with end split reinforcement for increased torque ratings. It utilizes standard TAPER-LOCK bushings for easy installation and removal.
Key Features
- Non-lubricated design assures trouble-free operation with visual inspection for preventive maintenance and split element for easy installation
- Reinforced torque-carrying tension cords prevent unexpected downtime with uniform and centered beads that prevent element pull out during operation
- Industry leading five-year limited warranty with over 50 years of proven performance
- ATEX approved with flexible element suitable for operation in ambient temperatures from -45°F to +180°F (neoprene alternative: -40°F to +210°F)
- Flexible element is replaceable without disturbing the coupled equipment and without the requirement for realignment
