Customized Steel Internal Ring Gear

These internal spurs have a cylindrical pitch surface and teeth which are parallel to the axis. However, the internal spur gear teeth are formed on the inner surface of a cylinder. Also, the precision engineered mating component will be an external spur gear. The teeth are machined during the shaping production step.

When manufacturing ring gears, increased durability is the most important factor to focus on achieving. Ring gears manufactured by Longsum allow for very close proximity operation versus externally toothed gears. Also, ring gears include customizable pressure angles to mate with nearly any accompanying gear. Our custom ring gear products are most ideal for light applications, through smooth, quiet operation. These products are manufactured to transmit power control between parallel shafts, that operate in a similar plane.

 All gears are packaged for safe shipping and convenient storage. Gears are carefully packaged using the most appropriate materials and method for the gear type.
