PIV Chains

PIV chains are also called Positively Infinitely Variable chains and are designed specifically for gearboxes. The chain has a variable pitch due to the chain's structure consisting of multiple individual plates that can move independently. This adaptability allows the chain to engage with grooves that have varying diameters from the edge to the center of the gearbox wheel. Please give us a call or submit a form online if you need any assistance identifying your PIV chain.

Dixie Industrial Sales is a trusted distributor and supplier of positively infinitely variable chains. Contact us to request a quote today!

Overview & Materials Of PIV Chains

PIV chains consist of multiple individual plates that move independently. The plates create a uniform pitch that maintains consistent contact with the gear system’s sprockets. The chain usually operates on pulleys or grooved wheels with varying diameters from the edge to the center of the gearbox wheel, allowing precise, uninterrupted speed and torque changes.

Manufacturers use durable and wear-resistant materials to make PIV chains, including:

  • Hardened steel
  • Alloyed steel

The exact choice of material depends on the size of the load and the application’s conditions or environment. Contact us to speak with one of our experts and find the exact PIV chain you need today!
