4 in. Aluminum Sheave w/ Bronze Bushing

The 4-inch Aluminum Sheave with Bronze Bushing is an essential component for boat lift systems. It is designed to guide the boat lift cable from the drive pipe to the boat cradle with precision and reliability. This sheave is specifically engineered to accommodate up to 5/16 inch thick 7 x 19 aircraft cable, making it suitable for a wide range of boat lift applications.

Key Features:

  1. Sturdy Construction: The sheave is made from high-quality 6061-T6 US aluminum, known for its strength, durability, and corrosion resistance. This ensures that the sheave can withstand the rigors of marine environments and provide long-lasting performance.
  2. Bronze Bushing: The sheave features a 3/4 inch bronze bushing bore, which provides smooth and efficient rotation of the cable. The bronze bushing enhances the overall performance of the sheave, reducing friction and wear on the cable.
  3. Easy Installation: The sheave is designed to be mounted on sheave housings using a 3/4 inch axle bolt (sold separately). This allows for easy and secure installation, ensuring proper alignment and smooth cable operation.
  4. Cable Compatibility: The sheave is specifically designed to fit up to 5/16 inch thick 7 x 19 aircraft cable commonly used in boat lift systems. The 7 x 19 construction of the cable provides excellent strength and flexibility, enabling smooth lifting and lowering of the boat.
  5. Precise Cable Groove: The sheave features a 7/16 inch cable groove that securely guides the boat lift cable, preventing it from slipping or jumping out of place during operation. The precise cable groove ensures reliable cable tracking and reduces the risk of cable damage.
