Movendis Poly-V Belts (also known as ribbed belts, flat belts, or accessory drive belts) are engineered for efficient power transmission in modern combustion engine accessory systems. Designed to transfer energy from the crankshaft to multiple engine components, they ensure reliable operation of alternators, air conditioning compressors, hydraulic pumps, power steering systems, and other auxiliary drives.

Built for OEM-grade performance, Movendis serpentine PK belts deliver superior contact efficiency and friction stability compared to conventional V-belts, enabling compact drive layouts, higher transmission speeds, and improved overall system efficiency.

Key Features & Performance Benefits

• High-efficiency Poly-V design with increased contact surface area
• Superior traction and reduced slippage, even in wet or demanding conditions
• Enables compact accessory drive system designs with smaller pulley configurations
• High flexibility for improved bending and counter-bending performance
• Stable power transmission at high linear speeds
• Low noise operation with improved NVH (noise, vibration, harshness) characteristics
• Excellent resistance to slip under variable load conditions
• Compatible with small diameter pulleys and backside idler systems
• Works with or without automatic tensioner systems
• Reduced tension loss and improved long-term stability
• Eliminates common drive issues such as vibration, noise, and belt flutter

Construction & Materials

• EPDM compound for high heat resistance and crack prevention
• Aramid fiber reinforcement for exceptional tensile strength and durability
• Precision form-ground manufacturing for consistent dimensional accuracy
• Engineered elastic belt variants for complex or high-demand drive systems
• Optimized profile geometry for improved pulley engagement and wear resistance

Typical Applications

• Automotive and industrial engine accessory drives
• Alternator systems
• Air conditioning compressors
• Hydraulic and power steering pumps
• Compact serpentine drive configurations
• Engines with small pulley or high-tension routing requirements

Movendis Poly-V belts are designed to meet or exceed OEM specifications, providing a robust, low-maintenance solution for high-performance accessory drive systems where reliability, efficiency, and durability are critical
