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 H1T 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]  ①The allowable torques shown in the table are calculated values according to the assumed usage conditions. Please see precaution for more details.
 ②There may be space in the casting between the two materials, but it will not affect the joint strength.

[Caution on Secondary Operations]  ①Please read “Cautions on Performing Secondary Operations”when performing modification and/or secondary operations of Worm Gears. Haguruma Kobo, the KHK's system for quick modification of KHK stock gears is also available.
 ②Tooth and the hub area, fastened by casting, is designed to have higher hardness than other parts of the gear. However, please avoid modifying parts except for the hub. Also, the hardness may decrease if secondary operations are performed.
