This product is a silicon nitride ceramic I-beam guide rail manufactured using hot pressing sintering technology, featuring a uniform dark gray matte texture with a precision ground surface. The product adopts an innovative I-beam symmetrical structure, combining an elongated main body with vertical rectangular protrusions at both ends and the middle to form a stable three-support point structure. This design ensures sufficient structural strength while achieving precise guide positioning functionality, making it particularly suitable for high-precision automated equipment applications.
