[Caution on Secondary Operations] © No secondary operations can be performed on these precision finished gears due to the applied carburizing process.

An example of KHK's inspection report on tooth profile and lead errors.

The precision grade of a spur gear (JIS B 1702-1:1998 and JIS B 1702-2:1998) is determined by factors such as single pitch error, pitch variation error, accumulated pitch error, tooth profile error, run out error, load error etc. For more details, please refer to the section "Precision of Spur and Helical Gears" in the technical reference.
