INA 5350041100 Alternator Decoupler Pulley

The INA 5350041100 is a high-quality alternator decoupler pulley designed to reduce vibration and noise while improving belt drive efficiency. This precision-engineered component features an integrated one-way clutch mechanism that isolates the alternator from engine vibrations and crankshaft irregularities, extending belt life and reducing wear on the charging system.

Key Features:

• Advanced decoupler design reduces belt slip and vibration
• One-way clutch mechanism protects alternator bearings from engine irregularities
• Engineered to OEM specifications for reliable performance
• Manufactured by INA, a leading supplier of automotive drivetrain components
• Direct replacement for worn or failed alternator pulleys

Alternator decoupler pulleys are essential components in modern belt drive systems, particularly in vehicles with start-stop technology or high-efficiency engines. The decoupling mechanism allows the pulley to overrun during rapid engine deceleration, preventing reverse torque from damaging the alternator while maintaining optimal belt tension.
