General Specifications

The DD series torque detector is the high-end equipment of the SS series to use in high speed measurement and large capacity measurement. It can be recommended to use in the heavy-duty application from DD-505 to DD-108. Double bearings provides three to five times the strength of our conventional torque detector under radial and thrust load, which enables direct coupling to automobile engines and saves the space as it makes a conventional intermediate bearing unnecessary. The oil drip lubricant (option) is necessary for the DD series.

Features

Double bearings provide three to five times the strength of the DSTP series under radial and thrust load.
Excellent at overload resistance.
