Self-lubricating Ceramic Shaft and Shaft seal

Short Description:

Self-lubricating Ceramic Shaft / Shaft seal have improved the material properties on the basis of maintaining the original high strength, acid and alkali resistance, and friction resistance of alumina products. The biggest feature is the reduction of the coefficient of friction. The shafts and shaft seals using this material show obvious advantages. For example: longer life, lower noise, better stability, and better protection of the motor.

The micro-textured self-lubricating ceramic material improves the comprehensive mechanical properties of the Al2O3 ceramic material. The fracture toughness and flexural strength of the brown self-lubricating ceramic shaft are 7.43MPa·m1/2 and 504.8MPa, respectively, which are about 0.4% and 12.3% higher than the ordinary alumina ceramic shaft, the maximum friction coefficient is reduced by about 33.3% and the minimum friction coefficient is reduced by about 18.2%.
