Altra Industrial Motion Corp F71810B5G Gearbox

The F71810B5G Gearbox from Altra Industrial Motion (Boston Gear) is a worm-gear speed reducer that lowers drive speed while increasing torque for industrial power-transmission applications. The model designation indicates a 10:1 reduction ratio and a B5 mounting flange, placing it in the inline worm reducer family commonly used in equipment where a compact footprint and reliable torque transfer are required. As part of the Altra Industrial Motion portfolio, this gear reducer is designed for robust service in manufacturing environments and is listed among Boston Gear/Worm Gear Reducers in distributor catalogs under the F718 series, including variants such as F718-60-B5-G and F718-10-B5-G. The 10:1 configuration makes it compatible with standard motor outputs and supports straightforward replacement or integration into existing drive trains, enabling higher torque at lower speeds without changing motor speed. This model is suitable for machines that demand steady, long-term torque transmission in a compact package.
