Internal gear supplier needed

Internal gear supplier needed

Internal gear supplier needed

(OP)
We need to build a small (roughly 1.5 inch diameter) planetary drive reduction system and were wondering if anyone knows of any suppliers who stock internal gears.   This is a low cost application so it doesn't lend itself to custom injection molding or gear cutting.  We were hoping that there is a supplier who stocks an internal gear close to this size and we'd then build from there.  Any assistance would be greatly appreciated.

(OP)
Thanks for the help, eromlignod. We did check out these two websites but the O.D. of the internal gears they offer is too large for our application. The I.D.'s are fine. Is there such a thing as a molded plastic internal gear supplier? We're looking for a gear more on the order of 1.5" O.D. (or less), 1.25" I.D. (or less). Maybe we're asking too much of stock components.

They are purposely made large on the OD so that you can turn them to the desired size to fit your housing.  They can be easily cut on a lathe by chucking them internally.
