Boston Gear 718-30-J Gear Reducer

Boston Gear 718-30-J is a compact, right-angle worm gear speed reducer offering a 30:1 single-stage reduction. It belongs to the company’s 700 Series, described as the backbone of Boston Gear’s worm-drive lineup, and is shipped as a J-assembly with no base mounting. In official literature and distributor listings, this unit appears as F718-30-B5-J and is commonly referenced simply as 718-30-J, confirming it is the same model across sources. The right-angle configuration places the input and output shafts at a perpendicular orientation, making it well suited for space-constrained drives. The 30:1 ratio provides a substantial reduction in speed within a compact footprint, enabling increased torque at reduced speed in equipment where a baseplate is not used or not required. The 700 Series worm reducers are a long-standing pillar of Boston Gear’s product line, designed for dependable, maintainable performance in industrial applications.
