Boston Gear F718-10-B5-J Inline Speed Reducer

The Boston Gear F718-10-B5-J worm-gear speed reducer is a 700 Series single-reduction unit that provides a 10:1 reduction in a compact package. It uses a 56C input flange and a center distance of 1.8 inches, enabling straightforward mounting to standard 56C motors with precise alignment in restricted spaces. The output is a solid, right-side shaft with a 0.875-inch (7/8 in) diameter, and the reducer features a cast-iron output shaft configuration for reliable torque transmission in everyday automation tasks. With a 10:1 ratio, this unit delivers notable torque multiplication while reducing output speed, making it suitable for small conveyors, packaging equipment, and other light- to moderate-load applications where space is at a premium. Variants such as RF718-10-B5-J are available without a base, offering mounting flexibility for OEM installations. Widely stocked across major distributors, the F718-10-B5-J is a common retrofit choice when upgrading or replacing existing 700 Series worm reducers, and its standard 56C flange compatibility simplifies coupling to compatible motors and drive components.
