Please see Page 227 for more details.② Backlash of racks vary depending on mating pinions. Please calculate the backlash in accordance with the backlash of the mating pinion and values in the table "Backlash of Rack Tooth (Amount of Tooth-Thinning)" (Page 191).[Caution on Secondary Operations]① Please read “Caution on Performing Secondary Operations” (Page 228) when performing modifications and/or second-ary 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 Round Racks. It causes contortion and deformation, and straightening processes are difficult to apply.[Caution on Product Characteristics]① The allowable forces shown in the table are the calculated values according to the assumed usage conditions. Please see Page 227 for more details.② In cases of using a molded flexible rack in an arc shape, proper meshing cannot be obtained as the pitch error and the tooth profile error increases. Be sure and adjust the center distance so that the pinion turns without any problem.③ Metal Flexible racks are not suitable for use when positioning accuracy is required.*SW Saw Blade Finished■ Example: Fastening of FRCP Metal Flexible RacksFastening with at head screwsSpot welding(Overhead view of Flexible Racks)Catalog No.Pitch mm(Module)Effectiveno. of teethShapeTotal lengthOutside dia.Height to pitch lineAllowable force (N)Allowable force (kgf)Weight(kg)Adh9DBending strengthSurface durabilityBending strengthSurface durabilitySROCP2.5-500SROCP5-500SROCP10-1000CP2.5(0.7958)CP5 (1.5915)CP10(3.1831)2009999R2R2R250550510101015309.213.4126.82474 16506610 91.8 324 130048.3 169 674 9.36 33.1 132 0.300.655.16
