Overview
The Dodge PS80-90 Para-Flex Spacer Coupling Element 2517 is a precision-engineered elastomeric coupling for industrial power transmission applications. This spacer coupling uses a 2517 series Taper-Lock bushing and is designed to connect shafts while accommodating angular, parallel, and axial misalignment. The natural rubber elastomeric element absorbs shock loads and vibration, reducing stress on connected equipment and extending component life. With no lubrication required, this coupling minimizes maintenance overhead while delivering reliable, smooth power transmission across a wide range of industrial machinery, motors, and driven equipment.
Key Features
- Elastomeric Element: Natural rubber absorbs shock and vibration for smooth torque transmission
- Misalignment Accommodation: Handles angular, parallel, and axial runout without binding
- Taper-Lock Bushed Design: Uses Series 2517 Taper-Lock bushing for secure, tool-free hub removal
- Precision Alignment Flats: Ensures repeatable positioning and easy installation
- Zero Maintenance: No lubrication needed; operates dry for cleaner, safer machine environments
- UL Listed: Meets industrial safety standards for certified equipment installations
Technical Specifications
The PS80-90 Para-Flex spacer hub is rated for power transmission in machinery ranging from small motors to large industrial drives. Standard configurations deliver reliable performance in demanding applications requiring misalignment tolerance and vibration dampening.
Typical Applications
- Electric motor to pump or fan coupling
- Conveyor drive systems and material handling equipment
- Compressor and air handling unit connections
- Industrial gearbox input/output shafts
- Adjustable-speed drive installations where misalignment tolerance is critical
