Speed Reducers - Boston Gear


New 80:1 and 100:1 ratios are now available in single reduction 700 Series worm gear speed reducers. The new models provide the compact size of a single reduction reducer with a lower purchase price than traditional double reduction units. Units are backwards compatible with all 700 Series industry-standard mounting dimensions. These economical reducers are ideal for low-torque, light-duty material handling, food processing and packaging applications. The new ratio reducers are available with projecting, quill or coupling input options. Hollow and solid (projecting) output options are also offered. 

Models are available with standard paint, BK/SBK coatings or stainless steel housings. Boston Gear’s 700 Series, the standard for modular worm gear construction, is known  throughout the industry for its durable, efficient, and trouble-free performance. The internal worm is specially-ground for enhanced efficiency and lower heat generation leading to prolonged product life. 700 Series reducers feature rugged cast iron or stainless steel housings with high-strength bronze worm gears mounted between heavy-duty tapered roller bearings. Quality materials and proper heat treating of the 700 Series components provide strength and durability. Large oil reservoirs also provide efficient heat dissipation and lubrication for longer operating life.
