① The allowable forces shown in the table are the calculated values according to the assumed usage conditions. 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
