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.
 ② 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). Areas of those products which have been re-worked are not black oxide coated.

[Caution on Product Characteristics]  ①Keyways are made according to JIS B1301 standards and Js 9 tolerance. For products with a tapped hole, a set screw is included as an accessory.
 ②The allowable torques shown in the table are calculated values according to the assumed usage conditions. Please see Selection Hints for more details.
 ③The 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.
 ④The use of S1T, S1T2 and S3T shaped Set Screws for fastening gears to a shaft is a method only applicable to gears for light loads. For secure fastening, please use dowel pins in combination.

[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.
 ②Due to gear teeth induction hardened, no secondary operations can be performed on tooth areas including the bottom land (approx. 2 to 3 mm).
