Please see Page 189 for more details.② The backlash of racks differ depending on the size of the mating pinion. Please calculate the backlash from the backlash value of the mating pinion. Also, please refer to the data in the section called ‘Backlash of Rack Tooth (Amount of Tooth Thinning)’ on Page 191. ③ After attaching the racks to the base, please fasten with dowel pins. Clamping only with mounting screws could possibly cause the screws to be broken, due to the heavy load.[Caution on Secondary Operations]① Please read “Caution on Performing Secondary Operations” (Page 192) 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 hardening Racks with bolt holes, due to deformation occurring at the mounting hole and the difficulty of straight-ening the rack after hardeneing.* The precision grade of J Series products is equivalent to the value shown in the table.
