Plastic Universal Joints

Plastic Universal Joints FAQ

1. What are Plastic Universal Joints?
   Plastic Universal Joints are lightweight, corrosion-resistant couplings designed to transmit torque between shafts while accommodating misalignments. They are particularly suited for intermittent applications where low mass, corrosion resistance, and electrical isolation are desirable.

2. What are the mechanical specifications of Plastic Universal Joints?

   • Torque Capacity: Suitable for low-torque applications
   • Speed: Up to approximately 1000 rpm
   • Backlash: Backlash-free up to 10^8 turns
   • Inertia: Low, making them appropriate for higher-speed applications
     These joints are not intended for continuous heavy-duty use but excel in applications requiring occasional or lighter loads.

3. What materials are used in Plastic Universal Joints?

   • Body Material: Typically acetal (Delrin), providing low mass and corrosion resistance
   • Hubs Material: Often brass, giving additional structural support
     Together, these materials offer a good balance of durability, corrosion resistance, and electrical isolation.

4. What are the environmental specifications of Plastic Universal Joints?
   Plastic Universal Joints function effectively across a range of environmental conditions and are well-suited for intermittent duty. However, they are not recommended for continuous high-torque applications, where metal joints may be more appropriate.
