About GREAT LAKES INDUSTRY, INC.

Great Lakes Industry, Inc. is a manufacturer of mechanical power transmission components, specifically torque limiters and sprockets with integrated bushings. The product line centers on overload protection and drive train alignment for industrial machinery. Torque limiters from Great Lakes Industry are available in bore diameters from 0.75 in to 2 in, with torque ranges spanning 25 lb-ft to 620 lb-ft, depending on the model. These units are designed to disengage or slip when a preset torque threshold is exceeded, protecting downstream equipment from damage due to jams or overloads. The sprocket and bushing assemblies combine a roller-chain sprocket with a tapered or straight bushing for mounting on shafts, offered in tooth counts from 20 to 29 and sprocket diameters from 3.5 in to 6.1 in. Both product families are constructed from steel or ductile iron, with no integrated teeth on torque limiter models, indicating a modular design that accepts separate sprockets or couplings. 3G Electric stocks multiple SKUs from Great Lakes Industry, covering the 250, 350, 500, and 700 series torque limiters, as well as TL-series sprocket/bushing combinations. These components are used in conveyor systems, material handling equipment, packaging machinery, and other rotating equipment where torque control and drive alignment are critical. The absence of proprietary tooth profiles on torque limiters allows engineers to pair them with standard ANSI roller-chain sprockets or other drive elements. 3G Electric provides global logistics support for these parts, enabling procurement teams to source replacements or new installations without manufacturer lead-time constraints. The product range is suited for maintenance, repair, and operations (MRO) applications as well as new equipment builds. No certifications or industry standards are explicitly listed for Great Lakes Industry components, but the dimensional and torque specifications align with common industrial practice for mechanical overload devices. Engineers should verify bore size, torque setting range, and shaft keyway dimensions against application requirements. 3G Electric’s catalog includes part numbers such as 250 x .750, 350 x 1.250, and 500 TL 50A29 Sprocket, facilitating direct cross-referencing with existing equipment.
