Steel Helical Gear Racks
① The allowable forces shown in the table are the calculated values according to the assumed usage conditions. Please see
Page 189 for more details.
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 Please use SH Helical Gears as the mating pinion.
④ These racks produce axial thrust forces. See page 167 for more details.
⑤ After attaching the racks to the base, please fasten with dowel pins. Clamping only with mounting screws could possibly cause the screws to be broken, due to a heavy load.
