Our vision remains unchanged: be your trusted local source for precision gear manufacturing, where expertise meets reliability.
A ring gear is also known as an annular gear or internal gear. In planetary gear systems, it's sometimes referred to as the annulus. Ring gears feature internal teeth that mesh with external gears (planet gears and sun gears) and are fundamental components in epicyclic or planetary gear assemblies used across automotive, aerospace, and industrial applications.
