Ceramic rods are widely used in industries such as precision machinery, semiconductors, medical devices, and chemical processing, thanks to their outstanding wear resistance, high hardness, corrosion resistance, and thermal stability.
We offer a variety of material options including zirconia, alumina, and silicon carbide. A wide range of ceramic rod types can be customized, including solid rods, hollow rods, stepped rods, threaded rods, locating pins, plungers, and more — all designed to meet the challenges of demanding operating environments.
Our ceramic rods are manufactured with high dimensional accuracy, excellent mechanical strength, and smooth surface finishes. They are ideal for applications such as bearings, seals, probes, and insulation supports, helping customers improve equipment performance and extend service life.
