Product Precautions
[Precaution on J Series Products]  ①Since J series are available-on-request products, it requires a lead-time within 2 working-days (excludes the day ordered), after placing an order. Number of products we can handle for one order is 1 to 20 units. In case of ordering products over 20 units, we shall submit a quote.
 ②Keyways are made according to JIS B1301 standards and Js 9 tolerance.
 ③Certain products which would otherwise have a very long tapped hole are conterbored to reduce the length of the tap. (Products marked with “ * “ are the tap size). For products which have a very short tapped hole (Products marked with “ ** “ are the tap size), the length of tapped hole is less than the nominal diameter (4mm or lesser for M4). Since tapped holes made for plastic products are easily broken, avoid too much tightening when fastening screws.
 ④For products, the use of S1T shaped Set Screws for fastening gears to a shaft is a method only applicable to the usage for light loads. For secure fastening, please use dowel pins in combination.

[Caution on Product Characteristics]  ①Significant variations in temperature or humidity can cause dimensional changes in plastic gears (MC Nylon gears), teeth diameter and backlash. Please see the section "Design of Plastic Gears" in the technical reference.
 ②The allowable torques shown in the table are calculated values according to the assumed usage conditions. Please see Selection Hints for more details.
 ③When the core O.D is the same as the hub diameter, you may see some serration on the hub. There in no effect on the strength of the gear.
 ④Without lubrication, using plastic gears in pairs may generate heat and dilation.
It is recommended to mate steel gears.
 ⑤The 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.

[Caution on Secondary Operations]  ①Please read “Cautions on Performing Secondary Operations” when performing modification and/or secondary operations for safety concerns. Haguruma Kobo, the KHK's system for quick modification of KHK stock gears is also available.
 ②Even though the holding strength at the material interface is designed to be stronger than the teeth, a secondary operation may weaken the holding strength.
 ③Plastic gears are susceptible to the effects of temperature and moisture. Dimensional changes may occur while performing secondary operations and during post-machining operations.
