Product Precautions
[Caution on Product Characteristics]  ①The allowable forces shown in the table are the calculated values according to the assumed usage conditions. Please see Selection Hints for more details
 ②The backlash value of a rack is calculated from the addition of 1/2 the backlash of the mating pinion and the value shown in the table “Backlash of Amount of Tooth Thinning”.

[Caution on Secondary Operations]  ①Please read “Cautions on Performing Secondary Operations”when performing modification and/or secondary operations of Racks. Haguruma Kobo, the KHK's system for quick modification of KHK stock gears is also available.
 ②Having a decarburized layer (approx. 0.5mm thickness) on the rectangular surfaces, the tooth tips cannot have the hardness you designate, if induction hardening is applied.
