CAUTION:: The slip torque which is dependent on the fastening torque can sometimes be less than the gear strength. Please use caution in selecting. The chart on the right shows the relationship between the slip torque and the fastening torque.

Fastening torque vs. Slip torque

CAUTION:: Gears with wider face widths such as the SS and SSA series can be used as mating gears to these.

NOTE 1: The bore cannot be modified. It is possible to pin the gear to the shaft to prevent slippage.
NOTE 2: Do not tighten the clamping screw without first inserting a shaft, or the bore will be permanently deformed and will not accept a shaft.
NOTE 3: The allowable torques shown in the table are calculated using the Lewis formula.
NOTE 4: The backlash values shown are the theoretical values of a pair of identical gears in mesh.
All dimensions shown in the above table(s) are listed in millimeters unless otherwise specified.
