Custom Silicon Carbide Gear Pump Bearing for Industrial Use

Customized Silicon Carbide Or Zirconia Sliding Bearing For Gear Pump

Product Introduction

Silicon Carbide (SiC) gear pump bearings are manufactured from high-performance reaction-bonded or sintered silicon carbide, offering exceptional corrosion resistance, wear resistance, and thermal stability. Designed for gear pumps in extreme operating conditions, they significantly extend service life and reduce maintenance costs.

Gear pumps transfer fluid via rotating meshing gears, while gear pump bearings are critical components supporting the gear shafts, directly affecting smooth operation, lifespan, and efficiency. Their roles include:

• Shaft Support – Withstand radial/axial loads to ensure precise gear alignment;
• Friction Reduction – Minimize wear at high speeds for energy efficiency;
• Chemical Resistance – Especially in chemical pumps (e.g., silicon carbide bearings resist acids/alkalis).
  Bearing failure can cause gear misalignment, leakage, or seizure, making material (e.g., metal, ceramic) and design vital for pump reliability.

Bearings act as the "joints" of gear pumps, synergizing with gears to define performance.
