Please see Page 31 for more details.② The backlash values shown in the table are the theoretical values for the normal direction for the ring gear in mesh with a 30 tooth SS type spur gear.③ Although the inside diameter of these gears are made to H8 tolerance, since the ring shape is easily deformed, some error may occur beyond the stated tolerance.[Caution on Secondary Operations]① Please read “Caution on Performing Secondary Operations” (Page 32) when performing modifications and/or secondary operations for safety concerns. KHK Quick-Mod Gears, the KHK's system for quick modification of KHK stock gears is also available.② Avoid performing secondary operations that narrow the tooth width as it affects precision and strength.＊For products not categorized in our KHK Stock Gear series, custom gear production services with short lead times is available.
