Grainger carries motion control couplings for small and dual-shaft applications. A single-beam control coupling can resist heat, chemicals and corrosion. A lengthwise spiral slot acts like a spring to help make the center flexible. For motion controls where two shafts must move at the same speed, in the same direction, a shaft control coupling can prevent misalignment. Use motion control couplings from Grainger to help run medical equipment, robots, metering devices, computers and more.
