Overview
The Dodge 011529 is a standard elastomeric coupling element for the Para-Flex PX40 tire coupling system. This natural rubber element delivers 429 in-lb torque at a maximum speed of 4500 rpm and is designed for non-lubricated, maintenance-free operation in industrial automation and power transmission applications. Para-Flex couplings employ a molded, non-lubricated elastomeric flexing member loaded in shear, with the flexible element compounded from natural rubber with textile cord reinforcement throughout and an extra layer of reinforcement adjacent to the split for added durability.
Key Features
- Patented cording transmits torque, offers a wear indicator, and absorbs shock loads to prevent damage to connected equipment
- Flexible element is replaceable without disturbing the coupled equipment and without the requirement for realignment
- Absorbs shock loads to prevent damage to connected equipment
- No lubrication and visual inspection which saves time
- Five year limited warranty on elements sizes PX40 thru PX200
Technical Specifications
- Angular misalignment capacity: 4°
- Parallel misalignment capacity: 0.125 in
- Axial misalignment (end float): 0.3125 in
- Operating temperature range for natural rubber: -45°F to +180°F
- Outside diameter: 4.25 in
- Torsional stiffness: 120 in-lb/deg
- Weight: 0.4 lbs
Typical Applications
Para-Flex couplings connect to harsh applications where the margin for failure is zero, including industrial pumps, motors, fans, compressors, and other rotating equipment requiring damping of vibration and shock. The elastomeric element absorbs transient torque spikes while maintaining precise alignment, making it essential for critical power transmission systems where equipment protection is paramount.
