Overview
The Dodge 011529 PX-40 is a standard elastomeric tire coupling element engineered for demanding industrial applications. As part of the Para-Flex coupling family, this 011529 PX-40 element delivers reliable torque transmission, shock absorption, and misalignment accommodation without requiring lubrication. The coupling element is manufactured with natural rubber and textile cord reinforcement, making it suitable for applications where vibration isolation and flexible power transmission are critical.
Key Features
- Non-lubricated design — eliminates maintenance and contamination risks
- Patented cording system — transmits torque while absorbing shock loads and protecting equipment
- Industry-leading misalignment capacity — accommodates 4° angular, 1/8″ parallel, and 5/16″ end-float simultaneously
- Wear indicator — visual inspection alerts when element replacement is needed
- Reinforced split design — reduces element fatigue during shock loading and extends coupling life
- Easy replacement — element is removable without disturbing connected equipment or requiring realignment
