4" × 3/4" Aluminum Sheave with ½" Oilite® Bronze Bushing – Made in USA

Perfect Pulley for Jet-Ski, PWC & Light-Duty Boat-Lift Cable Systems

Upgrade your PWC or small-craft lift with our 4" × 3/4" aluminum sheave, machined and assembled in the USA. The ½" Oilite® bronze bushing delivers self-lubricating performance while the compact bore matches ½" axle bolts and pins— a common size on jet-ski and light-duty lift cradles.

Key Features

• Made in USA Quality: CNC-turned, balanced and inspected for tight tolerances.
• 4" Diameter × 3/4" Width: Fits standard light-duty pulley brackets.
• ½" Borehole: Ideal for ½" axle bolts or clevis pins on PWC lifts.
• Oilite® Bronze Bushing: Self-lubricating insert reduces friction & wear.
• Marine-Grade Aluminum: Lightweight, corrosion-resistant alloy resists salt & spray.
