Product Description
Silicon Nitride Ceramic Irregular Slide Block - Multi-Functional Integrated Precision Structural Component
Product Overview
This silicon nitride ceramic irregular slide block is manufactured using gas pressure sintering technology, featuring a uniform dark gray color and mirror-level smoothness achieved through precision polishing. The innovative integrated structural design combines an irregular block main body, semi-cylindrical positioning protrusion, and through-type circular hole to achieve multifunctional structural integration. This composite design ensures precise positioning functionality while providing excellent mechanical support, making it particularly suitable for high-precision industrial equipment applications.
