What General Kinematics does

General Kinematics (GK) is a privately held, family-owned manufacturer of vibratory and process equipment founded in 1960 and headquartered in Crystal Lake, Illinois. The company designs and builds Two-Mass vibratory equipment used to move, screen, separate, and process bulk materials in heavy-industry applications, including foundry lines, recycling systems, mining operations, bulk processing, and wood processing. Its installed base of more than 40,000 units spans 35 countries, and customers include 150 US power plants, all major US and European automotive OEMs, and named industrial buyers such as TAZ Recycling, American Wood Fibers, and Badger Alloys.

The company's core technology is its proprietary Two-Mass vibratory platform, protected by more than 200 patents — reportedly four times the patent count of its nearest competitor. GK operates a dedicated material testing lab for application engineering and supports customers through seven global facilities in the United States, Germany, Poland, two sites in China, India, and Australia. The product offering has expanded beyond core vibratory equipment into an integrated portfolio of sub-brands: Tuffman, Cyrus, GK Llambeck, and GK Systems, covering vibratory feeders, pneumatic conveying, and engineered process systems. The most recent digital offering, APEX Wireless, provides remote condition and performance monitoring on installed equipment.

Revenue is generated primarily through engineered-to-order equipment sales into capital projects at enterprise industrial customers, with ISO 9001:2015 certification supporting procurement into regulated buyers. The company is in its third generation of family ownership under the Musschoot family and does not publicly disclose financial results, though its 2025 Inc. 5000 placement indicates multi-year organic growth sufficient to rank among the fastest-growing private US firms. The business model is reinvestment-funded rather than venture- or private-equity-backed, and growth is supported by global expansion, sub-brand development, and services tied to the installed base.
