MIDDIA 95% Alumina Ceramic Wheel and Guide Roller Component for Industrial Furnaces (Item No. AC12)

Engineered for high-temperature continuous kilns, heat treatment furnaces, conveyor systems, and glass annealing lines, MIDDIA AC12 95% Alumina Ceramic Wheels and Guide Rollers offer reliable thermal and mechanical performance. Manufactured from high-grade 95% Aluminum Oxide (Al2O3), these precision-molded ceramic wheels feature extreme surface hardness (Rockwell HRA80–88), high mechanical strength, and outstanding resistance to abrasive friction. Designed with smooth central bores, outer drive grooves, and chamfered edges, AC12 wheels function effortlessly as guide pulleys, wire traction sheaves, and furnace roller supports in continuous high-temperature environments reaching up to 1500 degrees Celsius. With a low coefficient of thermal expansion and high thermal shock resistance, they resist surface micro-cracking, deformation, and thermal sagging under rapid thermal cycles. Non-porous, chemically inert, and highly corrosion-resistant against hot gas oxidation, harsh fluxes, and industrial chemicals, these ceramic rollers outlast conventional heat-resistant steel wheels by multiple service lifespans without requiring liquid lubricants. MIDDIA provides full OEM/ODM manufacturing based on customer technical drawings, custom inner/outer diameters, groove geometries, low MOQ wholesale orders, and fast global factory delivery.
