[Cautionon Product Characteristics]© Although the dimensions of the keyway are made to the JIS (Js9) tolerance, there may be some deviations due to the effects of the heat treatment.
© The allowable torques shown in the table are the calculated values according to the assumed usage conditions.
Please see page 35 for more details. ® The backlash values shown in the table are the theoretical values for the backlash in the normal direction for a pair
of identical gears in mesh.
© Products marked with "**" have a small amount of material between the corner of the keyway and the tooth root. This mode of failure must be considered when selecting these gears. For details, please see our web site.
