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 253 for more details.③ Dimensions of the outside diameter, the overall length and crown to back length are all theoretical values, and some differences will occur due to the corner chamfering of the gear tips.④ Without lubrication, using plastic gears in pairs may generate heat and dilation. It is recommended to mate with steel gears.■ Dimensional tolerance table(Unit : mm)[Caution on Product Characteristics]① The allowable torques shown in the table are the calculated values according to the assumed usage conditions. Please see page 253 for more details.② The bore tolerance is generally -0.05 to -0.3 but may be + values at the central por-tion of the hole.③ To find the dimensional tolerance of these gears, please see the Dimensional Toler-ance Table.[Caution on Secondary Operations]① Avoid performing secondary operations as reworking material may expose air bub-bles (voids).*The precision grade of this product is equiv-alent to the value shown in the table.
