Please see Page 189 for more de-tails.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 Tolerance of “d” dimension of SRO6-1000 is h10. [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 Please avoid hardening of Round Racks. It causes contortion and deformation, and straightening processes can hardly be applied.*SW Saw Blade FinishedRound RacksStainless Steel Round RacksModule 1~3SUROSpecificationsPrecision gradeKHK R 001 grade 5Gear teethStandard full depthPressure angle20°MaterialSUS303Heat treatment ―Tooth hardness(less than 187HB)AdDSWSWCatalog No.ModuleEffectiveno. of teethShapeTotal lengthOutside dia.Height to pitch lineAllowable force (N)Allowable force (kgf)Weight(kg)Adh9DBending strengthSurface durabilityBending strengthSurface durability[Caution on Product Characteristics]① The allowable forces shown in the table are the calculated values according to the assumed usage conditions.
