Belt Tensioner Pulley with Single Bearing
Detroit Diesel

The belt tensioner pulley with a single bearing is a vital component that preserves the correct tension on your engine’s serpentine or flat belts, directly impacting accessory operation and engine performance. With a width of approximately 6 inches, it supports the belt's alignment and prevents slipping or misalignment during operation. Constructed from sintered steel, the pulley offers excellent strength and thermal stability, ensuring long-term durability. The single bearing design allows smooth rotation, reducing belt wear and noise. Its resilience across a broad temperature range, from -40°C to +130°C, makes it suitable for demanding environments. Properly functioning tensioner pulleys are crucial for preventing belt failure, which could lead to accessory malfunction or engine overheating.
