Pump-Motor Coupling Bell - NEMA 56C-145TC

The bell housing (pump-motor mount) directly connects an SAE flange hydraulic pump to a NEMA C-face electric motor, ensuring precise shaft alignment and securely enclosing the coupling. Its design eliminates the need for brackets, additional bases, leveling shims, and coupling guards. Each mount is precision machined (to Magnaloy standards) to ensure concentricity within .003” from the motor pilot to the pump pilot.

Verify your NEMA motor's frame size, your pump's SAE flange, and the shaft lengths to confirm compatibility with this part.

General Specifications and Dimensions:

• Line: For NEMA 56C / 143TC-145TC electric motor.

• Component: Horizontal coupling mount/bell housing.

• Material: High-strength cast aluminum (larger mounts available in welded steel).

Coupling Data (Motor Side - NEMA Standard):

• Pilot Diameter (AK): 4.500" (114.3 mm).

• Bolt Circle (AJ): 5.875" (149.2 mm).
