What Dorris Gear Drives does
Dorris Gear Drives (The Dorris Company, Inc.) is a manufacturer of industrial gear drives and speed reducers, founded in 1946 and headquartered at 17430 Malyn Blvd, Fraser, Michigan. The company produces a portfolio of mechanical power-transmission products including Shaft Mount TR Series reducers, Screw Conveyor TL/TLC Series drives, Base Type drives, TD Series, Direct Drive units, Right Angle drives, and C-Face motor adaptors, serving industrial customers across multiple sectors. The company operates as a wholly-owned subsidiary of Supreme Gear Company, and its products are documented in company materials as an "industry standard" in industrial gearing.
The product line is built around heavy-duty mechanical power-transmission components, with proprietary design elements including a quick-release bushing system and a two-piece ribbed bushing with integrated sealant groove, intended to simplify mounting, reduce maintenance time, and improve sealing performance in harsh industrial environments. The portfolio spans horizontal and right-angle configurations, with both shaft-mount and base-mount form factors, alongside screw conveyor and direct-drive variants for specialized applications such as grain handling, aggregate processing, food manufacturing, recycling, and specialty architectural/structural drive work (e.g., the Los Angeles Cathedral). The TLC Series and TRC Series C-face motor adaptor variants were introduced as explicit SKU extensions of the legacy TR/TL families to capture retrofit and OEM mounting-standardization demand.
Dorris distributes through a four-channel go-to-market: direct sales, an independent sales-representative network organized by U.S. state and Canadian province, regional distributors, and e-commerce via its corporate website. The customer base spans aggregate processing, grain handling (including the Saskatchewan Wheat Pool's Project Horizon program), food processing, recycling, and specialty applications, with positioning that explicitly targets both "Largest mills to smallest manufacturers." As a privately held subsidiary with no public financials, the company does not disclose revenue or headcount, and no recent funding, M&A, or leadership transitions are documented in the input.
