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.

Our factory and processing machine:
We have three factories in China, can meet the needs for different
custmers, and also we have advanced pressing, sintering and
processing machines.
Why choose us:
According to the structure difference, it can be divided into:
external gear pump and internal gear pump. Our company has ample
production experience of both kind of the gear pump sliding bearing
in material of silicon carbide. We did supply these SSiC sliding
bearing for Germany Witte for many years.
