Overview
The Dodge 011109 Para-Flex coupling element is a standard elastomeric tire coupling component engineered for medium-duty industrial power transmission. As part of the Para-Flex tire coupling system, this PX90-sized element absorbs shock and damps vibration to protect connected equipment and extend machinery life. The coupling element is manufactured from natural rubber and operates in close-coupled shaft configurations.
Key Features
- Elastomeric construction: Natural rubber material provides superior vibration isolation and shock absorption
- Misalignment accommodation: Angular misalignment of 4°, parallel misalignment of 0.125 in, and axial misalignment of 0.3125 in
- Industry-leading problem solver: Absorbs shock and damps vibration to protect downstream equipment
- ATEX certification: Suitable for use in hazardous environments where safety compliance is critical
- No maintenance lubrication required: Elastomeric design eliminates greasing and oil maintenance
