Is AGMA Class 16 the tightest tolerance gear class?

[Ranger Mike]

Does anyone here have knowledge of AGMA Gear classification standards relating to classes or grades? I understand the AGMA std was revised in 2015 but many still follow the AGMA 2000 standard. Is Class 16 AGMA the tightest tolerance gear class?

The AGMA website lists a phone number to "talk to our staff." Give that a try!
