  • Key functions & working principle
Working Principle 1. Belt Guidance: The idler pulley is mounted at a fixed position in the engine’s accessory drive system, guiding the serpentine belt along the optimal path between driven components (alternator, water pump, air compressor).
2. Tension Assistance: Works in conjunction with the automatic belt tensioner to distribute belt tension evenly – preventing localized stress and extending belt life.
3. Low-Friction Rotation: The sealed ball bearing allows the pulley to rotate freely with the belt (minimal friction), reducing energy loss and belt wear.
4. Alignment Maintenance: Precision machining ensures the pulley rim is perfectly perpendicular to the belt path – avoiding belt off-tracking, fraying, or premature failure.
Core Functions 1. Guide Belt Routing: Ensures the serpentine belt follows the correct path to drive all engine accessories – critical for proper system operation
2. Reduce Belt Wear: Low-friction rotation and belt-friendly rim design minimize abrasion – extends belt service life by 30–50%
3. Dampen Noise: Rubber/PU coating absorbs vibration between the belt and pulley – reduces operational noise (e.g., engine idle noise)
4. Maintain Alignment: Prevents belt off-tracking and misalignment – avoids costly damage to accessories (e.g., alternator pulley damage)
