Poly Ether Ether Ketone (PEEK) also has quality properties. A single piece order is acceptable and will be produced as a custom-made gear. For details on quotations and orders please see page 8.Module 1[Caution on Secondary Operations]① Please read “Caution on Performing Secondary Operations” (Page 32) when performing modifications and/or secondary operations for safety concerns. KHK Quick-Mod Gears, the KHK's system for quick modification of KHK stock gears is also available.② Plastic gears are susceptible to the effects of temperature and moisture. Dimensional changes may occur while performing secondary operations and during post-machining operations.[Caution on Product Characteristics]① Significant variations in temperature or humidity can cause dimensional changes in plastic gears (MC Nylon gears), including bore size (H8 when pro-duced), tooth diameter, and backlash. Please see the section “Design of Plastic Gears” in separate technical reference book. (Page 101).② The allowable torques shown in the table are calculated values according to the assumed usage conditions. Please see Page 31 for more details.③ Without lubrication, using plastic gears in pairs may generate heat and dilation. It is recommended to mate them with steel gears.④ The backlash values shown in the table are the theoretical values for the backlash in the normal direction of a pair of identical gears in mesh.PS1-1515S161215170.410.0420~0.320.0027PS1-16161216180.450.0460.0030 PS1-18181418200.530.0540.0041PS1-20201620220.610.0630.0053PS1-222281822240.690.0710~0.340.0062 PS1-24242024260.770.0790.0077PS1-25252025270.820.0830.0082PS1-26262026280.860.0880.0086 PS1-28282228300.940.0960.010 PS1-30302530321.030.100.013PS1-32322632341.110.110.014PS1-35352635371.250.130.016PS1-36362836381.300.130.018 PS1-4040103540421.480.150.024PS1-45453545471.710.170.028 PS1-48483548501.860.190.030 PS1-505050521.960.200.032PS1-555555572.180.220~0.360.037 PS1-606060622.410.250.042PS1-656565672.640.270.048PS1-70704070722.870.290.057PS1-757575773.110.320.064 PS1-808080823.340.340.071 PS1-858585873.570.360.079PS1-909090923.800.390.087PS1-95954095974.030.410.095 PS1-1001001001024.270.440.10SpecificationsPrecision gradeJIS grade N9 (JIS B1702-1: 1998)*JIS grade5 (JIS B1702: 1976) Gear teethStandard full depthPressure angle20°MaterialMC901Heat treatment ―Tooth hardness(115~120HRR)Face width (E)10Hub width (F)10Total length (G)20Screw offset (J) 5
