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.
