摘要： PROBLEM TO BE SOLVED: To provide a sleeve for die casting in which thermal insulation properties of molten metal are more improved, and the loosening of a shrinkage fitting can be prevented even when used as the one for a hot chamber type die casting machine.
SOLUTION: The inside of an outer cylinder consisting of a metallic material having a low thermal expansibility is provided with an intermediate cylinder consisting of sialon ceramics. The inside of the intermediate cylinder is provided with an inner cylinder consisting of silicon nitride ceramics having a thermal conductivity of ≥60 W/(mK) at an ordinary temperature to compose the sleeve. A heating medium passage is formed on the inside of the outer cylinder or the outside of the intermediate cylinder located on the boundary part between the outer cylinder and the intermediate cylinder.

摘要： PROBLEM TO BE SOLVED: To provide a roller bearing used in a continuous hot-dip metal plating bath, which prevents hot-dip metal from being enclosed and remaining in a space between a ceramic member and a metallic bearing holder for holding the member, when raising the bearing from the bath, and which thereby prevents the ceramic member from cracking. SOLUTION: The bearing comprises the metallic bearing holder and the ceramic member. The metallic bearing holder is characterized by having a groove all over the length in the shaft direction on its region of which the bearing receives load due to sliding with a roll shaft, arranged inside the bearing holder, by arranging the ceramic member with a partly cylindrical shape having a curved surface on a sliding side with the roll shaft, in the groove of the bearing holder, and by forming a space for discharging the hot-dip metal, between the internal surface of the groove on the bearing holder and the external surface of the ceramic member which faces to the holder.
