Our standard 700 Series - the heart of Boston Gear's speed reducer product line - has been serving many industries reliably for over 40 years. Its proven modular design has set the industry standard for performance and is the most imitated product in today's worm gear speed reducer market.
features
Large oil reservoir provides efficient heat dissipation and lubrication for longer life
Housing is straddle milled top and bottom for precise alignment
Rugged housing fabricated of fine-grained cast iron for maximum strength and greater precision during worm and gear alignment
High strength steel output shaft ensures capacity for high torque
Pipe plugs allow easy fill, level and drain in any mounting position
Super finished oil seal diameters on both input and output shafts extend seal life
caution
Drives used in a vertical mounting application may require additional pipe plugs and/or grease fittings for proper lubrication and are considered special.
High loads, high ambient or operating temperatures, and unusually contaminated atmospheres will require more frequent relubrication.
