HNA Advanced Zirconia Liners are significantly harder than Chromium alloy bimetallic liners,and are tougher than any
other ceramic liner available.The pure Zirconia ceramic used in these liners are extremely resistant to abrasion,corrosion and heat and are currently the premium liner offered today in its type.Due to the high hardness of the ceramic surface,they wear substantally less than other liner types and operate over 10,000 hours when the correct conditions are present.The cost per operating hour can be much less than (only 1/5 as)that of the bimetal liner types,as well as only 15 consumption of pistons,which greatly benefits the end users in reducing operation cost.
