Selection and Installation
Select the correct adapter flange according to the gearbox and flexible coupling mounting requirements. The following specifications must be checked:
- Flange Type: Nominal mounting configuration in inches
- Length: Overall adapter length in mm
- Center 1 and Center 2: Centering diameters and configurations
- Bolt Circle 1 and Bolt Circle 2: Mounting bolt circle diameters
- Mounting 1 and Mounting 2: Number and diameter of mounting holes
Both connection sides must match the corresponding gearbox and flexible coupling. Verify the centering dimensions, bolt circle diameters, mounting hole patterns and available installation length before ordering.
