CAUTION: To use the molded flexible rack with a 20 tooth pinion, the radius of curvature for an external or internal arc must be greater than 150mm.
CAUTION: Molded plastic gears are inherently less precise than metal gears. The table on the right shows the dimensional tolerance of these racks. The overall length is 200010mm.picture1
CAUTION: These molded flexible racks are not suitable for applications where positioning accuracy is required.
NOTE: Allowable transmission forces shown in the table are the values calculated from the Lewis formula. The allowable bending forces are the values for Duracon M90.
