The P-Type Toothed Chain (also known as a slat chain or laminated chain) is the core mechanical component designed specifically for PIV (Positive Infinitely Variable) Drives. Unlike standard roller chains, the P-Type chain features a unique set of sliding slats that adapt to the grooved radial teeth of the PIV pulleys. This design ensures a positive, non-slip power transmission while allowing for seamless, stepless speed adjustment. It is engineered to withstand high torque and continuous friction in heavy-duty industrial transmission systems.

Our PIV Variable Speed Chains are manufactured using high-strength alloy steel with specialized heat treatment to ensure maximum wear resistance and longitudinal stability. Whether you are maintaining a vintage PIV gearbox or outfitting a new high-precision textile or paper processing line, our chains offer the durability and exact pitch alignment required for smooth operation. We provide a full range of standard models, including P0, P1, P2, P3, and P5, each precision-matched to specific link counts and power ratings.

Key Performance Benefits
Positive Non-Slip Drive: Slatted design ensures 100% positive engagement with pulley grooves, eliminating power loss from slippage.

Stepless Speed Regulation: Facilitates smooth, infinitely variable speed changes for precise process control.

High-Grade Alloy Steel: Constructed with premium hardened steel for superior tensile strength and extended service life.

Precision Pitch Control: Accurate link-to-link dimensions (P0 to P5 series) ensure minimal vibration and noise at high speeds.

Heavy-Duty Reliability: Designed to operate under high-tension and variable load conditions in demanding industrial environments.

Universal Compatibility: Standardized dimensions make these chains the perfect replacement for OEM PIV drive units globally.
