DieQua Servo Worm (DSW) Flanges
There are few industry standards regulating servo motor mounting dimensions. Because of this, DieQua stocks an enormous number of different flanges and mounting components. Additionally, we can produce custom motor adapter flanges to accommodate a wide range of non-standard servo and stepper motors to our reducers. There are two ways to select the proper mounting flange and coupling:
-
Option 1 (Most Accurate): Provide us with your motor performance data and mounting dimensions. Our technical staff will review the dimensions, select the proper flange and coupling, and double-check the motor torque data to ensure your gearbox is properly sized.
-
Option 2: Use the selection tables provided below to identify the proper flange plate that mates with your specific motor. Please designate the corresponding 2-digit motor flange config code in the part number when configuring your Servo Worm.
