What Nexen Group does

Nexen Group, Inc. is a privately-held, family-owned US manufacturer of precision motion control and power transmission components, headquartered in Vadnais Heights, Minnesota, with manufacturing concentrated in a state-of-the-art facility in Webster, Wisconsin housing over 80 multi-axis CNC machine tools. The company traces its lineage to Horton Manufacturing (founded 1902) and was reorganized into Nexen Group in 1999 by Hugh (Hutch) K. Schilling, Jr.

The portfolio is organized into four product categories: Rotary Motion Control (rotary indexers, roller pinion gears, precision brakes, harmonic gearheads), Linear Motion Control (roller pinion racks, profile rail brakes, rod locks), Power Transmission (friction and tooth clutches, friction brakes, torque limiters, tension control products), and the NexSafe sub-brand of ISO 13849-1 functional safety-certified products. The flagship Roller Pinion System uses bearing-supported rollers engaging a patented tooth profile to deliver zero backlash, 99% mechanical efficiency, accuracy better than 2.2 arc-seconds, and tangential velocities up to 11 m/s; the proprietary Raydent coating enables lube-free operation at moderate speeds. NexSafe servomotor brakes, profile rail brakes, and rod locks are certified by Intertek to ISO 13849-1 Category 4 / Performance Level e.

Nexen operates a hybrid go-to-market: direct e-commerce via its website with full CAD/technical documentation downloads for registered users, a global network of independent distributors and trained sales representatives, and wholly-owned regional sales offices in Wemmel, Belgium (Europe) and Tokyo, Japan (Japan/Korea/Taiwan), with an authorized distributor covering Australia/Southeast Asia/New Zealand. Customers span aerospace, robotics and factory automation, medical equipment, machine tools, automotive production, packaging/material handling, semiconductor fabrication, solar/renewable energy, and mining OEMs. The company is ISO 9001:2015 certified and CE/REACH/RoHS compliant. No public revenue is disclosed.
