Bell Housing Pump-Motor - NEMA 182TC-256TC

The bell housing (pump-motor mount) directly connects an SAE flanged hydraulic pump to medium and large-format NEMA C-face electric motors, ensuring precise shaft alignment and securely enclosing the drive coupling. Its integrated design completely eliminates the need for brackets, additional bases, leveling shims, and custom-fabricated coupling guards.

Machined to the highest industrial precision standards, each mount guarantees concentricity within 0.003" from the motor pilot to the pump pilot, reducing premature bearing wear and extending system lifespan.

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

General Specifications and Dimensions:

• Line: For NEMA 182TC, 184TC, 213TC, 215TC, 254TC, and 256TC electric motors.

• Component: Heavy-duty horizontal coupling mount/bell housing.

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

Coupling Data (Motor Side - NEMA Standard):

• Pilot Diameter (AK): 8.500" (215.9 mm).

• Bolt Circle (AJ): 7.250" (184.15 mm).

• Front Fasteners: 4 threaded holes at 1/2"-13 UNC.

Coupling Data (Pump Side & Interior):

• Pump Flange: Compatible with SAE standards. (Check your pump's AK pilot diameter and the 2 or 4-bolt configuration depending on the specific model).

• Internal Depth / Length: Designed to accommodate industrial jaw couplings, maintaining a safety clearance of 0.10" to 0.25" between the motor and pump shaft ends to prevent axial friction.
