Industrial 800160-AY 168WG21B Gearmotor Gearbox

Reliance Electric's Master XL gearmotor gearbox, part number 800160-AY, model 168WG21B, is a compact Master XL gearmotor assembly within the Reliance lineup that combines a gearhead with a motor housing into a single, install-ready package designed for industrial environments. The configuration is specified with a 10:1 reduction ratio, meaning the output shaft turns at about one-tenth of the input speed, while the geartrain increases torque relative to the motor input, enabling greater turning or lifting force at reduced speeds. The 800160-AY and 168WG21B identifiers uniquely locate this exact specification within the Master XL family, supporting precise ordering, replacement, or refurbishment decisions without ambiguity. Public listings and catalog references consistently cite the 800160-AY / 168WG21B designation for this model, indicating its recognition as a standard Master XL gearmotor gearbox configuration in both new and surplus inventories.
