Ceramic Bolts, Rods & Plungers | High Strength Industrial Components
Ceramic Rods, Shafts & Plungers for High-Wear Applications
Ceramic round rods and shafts are specified as direct replacements for hardened steel in applications where wear resistance, corrosion resistance, and electrical insulation matter more than raw toughness — pump plungers, agitator shafts, and precision guide rods among them. Because these parts are often ground to a running fit, dimensional consistency along the full length matters as much as the material itself.
Common applications
High-pressure pump plungers
Agitator and mixer shafts (chemical processing)
Guide rods and locating pins
Structural fasteners in corrosive or high-temp environments
Materials available
Alumina, zirconia, aluminum nitride, silicon nitride, boron nitride, silicon carbide — link to material pages.

Manufactured using advanced ceramic materials such as alumina and zirconia, these components provide exceptional hardness, thermal resistance, and chemical stability. Unlike metal parts, they do not rust, corrode, or deform under extreme conditions.
Ceramic bolts ensure secure fastening in high-temperature systems, while ceramic rods are widely used for structural and insulation purposes. Ceramic plungers are ideal for high-pressure pumping systems, offering superior wear resistance and smooth operation.
These properties make ceramic components highly suitable for demanding industrial applications where performance and durability are critical.
