For example, the KD0 ( radial runout of the sleeve cup to inside diameter) is less than 0.004 of the product from SKF company. And our products have also arrived at this level. Now, we are researching and developing the product with zero KD0 value. We researched and developed compound salt bath processing technique to be used for adapter sleeve product, and has obtained success in 2003. The compound salt bath technology was awarded the Second Prize of the National Science and Technology Progress as well as the United Nations Invention Award. The adapter sleeve treated by compound salt bath has high-wearring feature which is thrityfold than quenching treatment, and the corrosion-proof feature is five times than stainless steel.
