Ceramic liners have better performance than metal liners in wearproof, corrosion resistant and service life. The material of ceramic liner is the most advanced international increased flexible Zirconium. As per this materal, the tenacity breakpoint is K10--15MPa ( 10 times of the ordinary material), bending strength is �?600--800Mpa with Weber coefficient is m18 and modulus of elestity of E200Gpa. These new ceramic liners are made for superior performance under tough corrosive and abrasive conditions. The HRC is more than 60�°. Each liner is machined to close tolerances to assure ease of installation and long liner life. Specification Inner size: 76mm Length: 98mm Outer size:82mm Thickness: 6mm
