Overview
The Dodge 120406 is a SDS-type quick disconnect (QD) bushing engineered for reliable power transmission and mechanical drive applications. This quick disconnect bushing features a 4° tapered design that enables simple, tool-free mounting and removal of sheaves, sprockets, and pulleys onto rotating shafts. Built to industry standards and manufactured from ductile iron with a steel bushing core, the 120406 delivers precise fit and durability in demanding industrial environments.
