| CAUTION: |
The products which are hardened by carburizing allow
no secondary machining. However, the back surface of B7 type gears are masked
during the process so that it is possible to drill and pin on this surface. |
| CAUTION: |
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. |
| NOTE: |
Although the dimensions of the keyway are made to the Js9 tolerance, there may be some deviations due to the effects of the heat treatment.
|
| NOTE: |
A set screw comes with these products.
|
| NOTE: |
The allowable torques shown in the table are calculated
according to JGMA Standards 403-01 and 404-01. All dimensions shown in the above table(s) are listed in millimeters unless otherwise specified.
