OVERVIEW & BENEFITS
The 4/3V6.90SK Sheave is a 4-groove V-belt pulley engineered for reliable power transmission in industrial drive systems such as softwash rigs, pressure washers, and pump setups. With a 6.9-inch outside diameter (OD) and compatibility with 3V belts, this sheave provides optimal torque transfer while minimizing belt slippage.
Designed to fit an SK taper-lock bushing, it offers a secure, vibration-resistant mounting solution. The precision-machined cast iron construction ensures long-lasting durability and consistent performance in harsh working environments.
