The Ironman GRG-BMQ-821-25-L-56 Left Angle Gear Reducer is a right-angle, single-reduction worm gear speed reducer that lowers input speed by 25:1 to deliver higher output torque for industrial power transmission. It features a left-hand solid output shaft, a C-face quill input, and is designed to accept NEMA 56C motors, making it suitable for driving conveyors, packaging equipment, and material handling systems in automated production lines. Built with a cast-iron housing, bronze worm gear, and a heavy-duty bearing arrangement, this unit thrives in continuous-duty environments and supports multi-position mounting. Key specifications include a 2.06 in center distance, 0.625 in input bore, 1.000 in output shaft diameter, and a left-hand output orientation; lubrication is factory-filled Mobil Glygoyle 460 PAG and shaft seals are Viton double lip seals. The GR Series unit is part of Ironman by Grove Gear (Regal Rexnord), with part number GRG-BMQ-821-25-L-56, and is commonly used in OEM replacement, machine repair, retrofit projects, and industrial upgrades—exactly the role system integrators rely on to keep conveyors, packaging lines, and processing equipment running smoothly.
