GWW vs ROK Comparison

Founded in 1927, W.W. Grainger originally distributed various motors via a mail-order catalogue. Over the course of the 20th century, the firm expanded into new industrial product categories and launched its first digital catalogue in 1995. Today, the company organizes itself into two segments focused on different customer bases. Its larger segment, high-touch solutions, offers a vast array of maintenance, repair, and operations, or MRO, supplies and bespoke inventory management services to larger businesses. Its smaller segment, endless assortment, operates two online platforms, Zoro and MonotaRO, that offer comprehensive catalogues of MRO supplies to smaller businesses. Grainger has operations throughout the world but primarily generates sales within the US.

With roots tracing back to the early 1900s, Rockwell Automation is the successor to Rockwell International, which spun off its avionics segment in 2001. It is a pure-play industrial automation company that operates through three segments. Its largest segment by revenue, intelligent devices, sells factory floor-level devices such as motors, drives, sensors, relays, and actuators. Its software and control segment sells visualization, simulation, and human-machine interface software and control products such as programmable controllers, computers, and operator terminals. Its smallest segment, lifecycle services, offers digital consulting, engineered-to-order services, and other outsourced services such as remote monitoring, cybersecurity, and asset and plant maintenance and optimization.
