APTS (Advanced Power Solutions Co., Ltd) is an experienced professional supplier from China of high performance wear-resistant parts.
Our material includes Silicon Carbide, Tungsten Carbide, Stainless Steel, Carbon Graphite which have been widely used in axial bearing for pump and compressor.
The
silicon carbide material is ultra hard and have a high thermal conductivity. This has led to silicon carbide being used in bearing and rotary seal applications where the increased hardness and conductivity improves seal and bearing performance. Process fluid-lubricated sliding bearings of silicon carbide are superior to conventional oil-lubricated sliding bearings in many respects: The machines or systems can have much simpler designs, complicated oil feed systems with maintenance-prone seals can be eliminated and the material properties are outstanding.
Thanks to the specific properties of sintered silicon carbide materials, the silicon carbide bearings can even operate in waters, acids and strong alkalis. The high hardness crushes foreign particles in the process fluid. The silicon carbide materials offer outstanding specific properties for use in sliding bearings.
We are capable to process the bearings according to your specific drawings.

Tungsten carbide is with good wear-resistance, excellent hardness and mechanical characters. Tungsten Carbide is ideal for high pressure applications due to a high modulus of elasticity which helps prevent face distortion. We have two primary types:
Nickel Bound (Ammonia applications should be avoided)
Cobolt Bound (May be used in Ammonia)
Carbon Graphite Axial Bearing has the advantage of excellent corrosion resistance, self lubricity, high coefficient of heat conductivity.
We have following grades of carbon graphite:
*Impregnated Phenolic Resin Graphite
*Impregnated Furan Resin Graphite
*Impregnated Antimony Alloy graphite
*High Purity Graphite
