| The S9111A-T619 series
is an extremely low backlash Bu-Ord Size 11 gearhead for servo
applications. All backlash components due to gear-induced factors are eliminated. Hence, the name "Zero-Backlash Gearhead" has been applied. The zero-backlash feature will remain fully effective up to the Z-B torque limit. In the Size 11 units, the Z-B torque limit (in oz. in.)is approximately 1/2 of the ratio. If the load torque exceeds the Z-B torque limit, backlash is introduced. The backlash will be eliminated when the load torque decreases below the Z-B limit. No permanent damage will occur providing the load torque does not exceed the unit's maximum rated torque. The angular compliance (not to be confused with backlash) is approximately 1 arc minute per ounce inch. |
