Custom Silicon Carbide Gear Pump Bearing
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.

We have three factories in China, capable of meeting different customer needs, equipped with advanced pressing, sintering and processing machines.
According to structure differences, gear pumps can be divided into external gear pumps and internal gear pumps. Our company has ample production experience with both types of gear pump sliding bearings in silicon carbide material. We have supplied SSiC sliding bearings to Germany's Witte for many years.
A: We are a factory in Beijing, China with over 40 years of experience producing ceramic bearings. We have established cooperative relations with many domestic and international companies.
A: We produce samples before mass production and strictly follow customer requirements. After production, we use inspection equipment for precise quality control. Our packaging includes foam and carton for double protection.
A: Ceramic deep groove ball bearings, ceramic angular contact ball bearings, hybrid ceramic ball bearings, ceramic linear bearings, and various ceramic balls.
A: As an integrated company with three factories and modern production/inspection equipment, we offer better delivery times and product quality.
