In applications where speed must be varied smoothly under load without stopping the machine PIV chains offer a solution that conventional gear systems simply cannot match. Used primarily inside Positive Infinitely Variable (PIV) drives, these chains are designed to transmit power while continuously adjusting speed ratios. As a specialised PIV Chains Manufacturer in India, JobWurx produces chains that deliver stable torque transfer, controlled articulation, and long service life inside variable-speed mechanical systems.
PIV chains are not general-purpose chains. They are precision components, operating under constant compression, tension, and sliding contact often all at once.
A PIV chain works inside a variable-speed drive by running between adjustable conical pulleys. As pulley spacing changes, the chain alters its effective pitch radius, allowing speed variation without interrupting power flow. This places unique mechanical demands on the chain.
JobWurx engineers PIV chains with a focus on dimensional stability and surface durability, ensuring consistent performance throughout the speed range.
Key technical characteristics include:
In practical terms, PIV chains are designed to handle torque levels ranging from several hundred Nm to over 10,000 Nm, depending on drive size and application.
As a dependable PIV Chains Supplier in India, JobWurx supports OEMs and maintenance teams operating equipment where speed control directly affects process quality. Poor-quality PIV chains lead to vibration, inconsistent speed output, and premature drive failure.
Industries rely on JobWurx PIV chains because they:
This reliability is critical in machines where speed precision governs product consistency.
PIV chains are commonly found in machinery where process control depends on mechanical speed variation rather than electronic drives.
Typical application areas include:
In textile and printing applications, PIV drives equipped with correctly specified chains can maintain speed accuracy within ±1–2%, even under fluctuating loads.
JobWurx also operates as a reliable PIV Chains Exporter from India, supplying chains for PIV drives used in international machinery. Export inspection focuses on link geometry, surface finish, and dimensional repeatability factors that directly influence drive performance.
Export customers benefit from:
These practices ensure long-term reliability in demanding global installations

PIV chains from JobWurx are manufactured using:
Available options include:
Surface treatments are carefully selected to balance wear resistance and friction characteristics.
Unlike roller chains, PIV chains do not fail due to simple tensile overload. Failure typically begins with surface fatigue or uneven link wear caused by poor heat treatment or dimensional inconsistency. Even small deviations can lead to noise, vibration, and unstable speed output. This makes precision manufacturing far more critical than raw strength.
