Durable

Durable

  • Oversized bearings for added support and greater durability
    • Gear-end bearings support rotor shafts, while drive-end double-row angular contact ball bearings fix the rotor position.
    • Prevents destructive axial rotor movement commonly caused by misaligned V-belt drives.
  • Durable single-piece cast iron cylinder with integral ribs
    • Provides greater strength and rigidity.
    • Ribs improve heat dissipation and prevent distortion that can affect internal clearances reduce performance.
  • Innovative rotor/shaft design machined from a single, high-strength ductile iron casting and dynamically balanced
    • Assures extra strength and rigidity to handle maximum loads on a continuous basis without fatigue, deflection or vibration.

Reliable

Reliable
