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.

[Caution on Product Characteristics]  ①A sets of miter gears must be identical in module and number of teeth, but opposite in spiral hands.
 ②The allowable torques shown in the table are calculated values according to the assumed usage conditions. Please see precaution for more details.
 ③Dimensions 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.
 ④These gears produce axial thrust forces. See precaution for more details.

[Caution on Secondary Operations]  ①Please read “Cautions on Performing Secondary Operations”when performing modification and/or secondary operations of Miter Gears. Haguruma Kobo, the KHK's system for quick modification of KHK stock gears is also available.
 ②In the illustration, the area surrounded with -- - - -- line is masked during the carburization process and can be modified. However, care should be exercised since the hardness is high (approx. HRC40, maximum).
