First off, the VersaPlanetary gear boxes were not designed to be used 1:1 with a 19,000 RPM motor. You are at the limits of the bearing's speed ratings. We do not sell the gearboxes for use as 1:1 gearboxes.

With that said, we designed these gearboxes with FRC teams in mind knowing they would modify them. Many, many items used in FRC are used outside their intended purpose. We just put a few hooks in the design to help teams use these gear boxes in many different ways (like the CIM mounting, for example).

The heat is not a problem. The ring gear section is very thin and the entire gearbox is made from aluminum. That combination conducts heat very quickly. All of the other gearboxes are getting this hot inside, but have either steel or thick aluminum housings and do not conduct heat to the surface as quickly.

Running the gearbox at 1:1 with an AM-9015 (free speed of 19,000 RPMish) is near the limit of the bearings. Also, if you have a fully charged battery you probably are at about 13.5 volts which means the free speed is even faster. Something to consider when using the VersaPlanetary at 1:1.
