- Reduces down time.
- Permits instantaneous phase adjustment of output shaft. Correction can be made intermittently or continuously by manual or other means.
- Eliminates step adjusting of speed.
- Assures positive power transmission.
- Shows control screw turns; relates input/output speed ratio.
- Allows space conservation.
- Minimum maintenance required.
- Assures long life and higher torque transmission.
- Allows easy mounting on machinery.
- Allows instant determination of oil level.
- Covers most applications of input and output.
- Accommodates special speed requirement, allows finer speed adjustment.
- Facilitates major maintenance.

The Specon Mechanical Differential Draw (MDD) Transmission differential draw design results in extremely accurate control of speed by compressing the speed range of a relatively wide mechanical variable speed device by appropriate connection to differential gearing. Inherent operating accuracies over 1000 times those of the variable element are attainable. This time-proven concept is combined with the service-proven components of the Specon MDD Transmissions to produce extremely accurate and reliable units with a long service life for Printing presses, paper machinery, film processing, paper cutoff, synthetic fiber, alternator drives, textile machinery, metering pumps and other Trim Speed applications requiring inherently high operating accuracy.
