What Boston Gear does

Boston Gear is a 1877-founded manufacturer of industrial power transmission components, operating as a brand within Regal Rexnord (NYSE: RR) following the 2023 acquisition of Altra Industrial Motion. The company is headquartered at 701 Carrier Dr., Charlotte, NC, employs 101-250 people, and offers more than 30,000 standard products spanning enclosed gear drives and motors, worm gear speed reducers (including the Gen2 SS700 stainless steel series), Micron TRUE planetary gearheads, open gearing, bearings, Centric brand clutches, and couplings/shaft accessories. Its flagship differentiation in food and beverage is the Domed Crown curved housing design combined with IP69K-rated 316 stainless steel enclosures and NSF International certification, addressing washdown hygiene and contamination prevention.

The business serves 17 documented verticals with food and beverage as the primary market and material handling, aerospace and defense, agriculture, medical imaging, motion control, wastewater, mining, packaging, marine, and power generation as secondary markets. Manufacturing of the SS700 Gen2 series is performed at the Charlotte headquarters. The company publishes extensive application profiles, catalogs, and innovation spotlights via altraliterature.com, maintains ISO 9001 certification, and holds a registered Domed Crown industrial design.

Boston Gear generates revenue through hardware sales of standard and custom-engineered components, priced on a quote basis rather than published rates, with 2-day standard lead times on select products. Go-to-market is primarily indirect through a global authorized distributor network covering 30+ countries, supplemented by direct customer service (1-888-999-9860), an OrderNet B2B ordering platform, and an eCatalog with CAD configuration. A product cross-reference tool enables replacement of competitor components, supporting capture of installed-base upgrade demand.
