The Boston Gear FWC752-1200-B5-G is a double-reduction, right-angle worm gear speed reducer from the Boston Gear 700 Series, the long-running cast-iron worm reducer line now produced under Regal Rexnord. The catalog code breaks down as follows: F denotes the flanged (quill-style) motor input, W the worm gearing, and C the double-reduction right-angle configuration; 752 is the frame size, corresponding to a 5.13 inch worm center distance; 1200 is the nominal gear ratio; B5 specifies a 56C NEMA C-face input flange; and G specifies a solid projecting output shaft on the left side. At a 1200:1 ratio this unit is built for extreme speed reduction and high mechanical advantage, delivering 12,610 lb-in of rated output torque from a fractional (0.620 HP) input, which makes it suited to very low-speed, high-torque duty such as slow conveyors, mixers, agitators, rotary tables, and indexing drives.
