Please see Page 189 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 Molded Flexible Racks are not suitable for use when positioning accuracy is required.④ To find the dimensional tolerance of these racks, please see the Dimensional Tolerance Table.
