DieQua Drives

Right Angle Servo Worm Gearheads

For applications requiring high precision and versatile output options, the High Performance Servo Worm series offers a compact, ultra-high-precision right-angle solution.

We also offer our Industrial Servo Worm Series, for a reliable, cost-effective option suitable for general automation and motion control.

DieQua Precision Worm (DPW 35-110)

The DPW series is designed for accuracy, offering ultra-high precision with backlash ratings of less than one arcminute for demanding positioning tasks. Its unique dual-pitch worm design allows for precise backlash adjustment by moving the worm axially relative to the ring gear. Combined with a proprietary special bronze alloy ring gear that reduces friction, the series ensures an optimized contact pattern and a significantly longer operational life

    DieQua Precision Worm (DPW) Flanges

    There are few industry standards regulating servo motor mounting dimensions. DieQua stocks an enormous number of different flanges and mounting components, additionally we can produce motor adapter flanges to accommodate a wide range of non-standard servo and step motors to our reducers.

    There are two ways to select the proper mounting flange and coupling. The first and most accurate way is to provide the motor performance data and mounting dimensions listed below. Our technical staff will review the motor mounting dimensions and select the proper flange and coupling. They will also double check the motor torque data to make sure the gearbox is properly sized for the motor. The second way is to use the table provided below to identify the proper flange plate that will mate with the motor of your choice. Please designate the corresponding motor flange 2-digit code in the part number when creating your DieQua Drives Servo Worn reducer part number.
