Boston Gear GB1051 Worm Gear

Boston Gear GB1051 bronze worm gear is designed to pair with Boston Gear worms in right-angle drive systems to provide high-ratio speed reduction in a compact envelope. This stock gear is 12 DP, has 30 teeth, and a 14.5° pressure angle, all in bronze, with a 0.500-inch face width to align with standard Boston Gear worm-gear sets. When used with the compatible Boston Gear worm, GB1051 delivers reliable meshing and efficient power transmission in non-intersecting, 90-degree shaft arrangements where space is limited. In historical Boston Gear catalogs, GB1051 is listed under the 0.500-inch face-width family with catalog reference 13628, confirming its intended size class within the bronze worm-gear lineup. GB1051 is designed to mesh with Boston Gear worms to form a 90° worm gear pair, enabling compact, high-reduction drives.
