Boston Gear 13138 G1060A LH C. I. Worm Gears

Boston Gear G1060ALH, catalog number 13138, is a cast-iron left-hand worm gear from the Altra line. The gear set specifies a 10 DP worm with a 20-tooth worm wheel and a 0.625-inch face width, standard dimensions that align with other Boston Gear worm-gear components for straightforward replacement and compatibility in existing drives. The G1060ALH is the left-hand variant of the G1060 family, paired with its right-hand counterpart G1060ARH (catalog 13136), both documented in Boston Gear's Altra catalog as 13136 and 13138 respectively. This product is part of the Altra Industrial Motion portfolio, reflecting the Boston Gear brand within a broader family of power transmission products. The 13138 designation identifies the left-hand CI worm gear in this series, with cast-iron construction for use in industrial gear-drive assemblies that require a 0.625-inch face width and 10 DP pitch.
