HERUN manufactures ceramic rods, tubes, shafts, pins, sleeves and protection tubes for insulation, wear, heat and corrosion applications. Custom outer diameter, inner diameter, length, holes, chamfers and surface finish are available.
The same basic shape can serve very different purposes depending on material, tolerance and finish.
Alumina tubes for electrical insulation, heating equipment, furnace supports, sensors and protection sleeves.
High-temperature tubes that protect sensors in furnaces, kilns and thermal process equipment.
Solid rods, pins, plungers and guides for wear-resistant contact and positioning.
Smooth wear components for pumps, valves, automation and sliding assemblies.
Perforated and multi-bore tubes for heating, electrical and process applications.
Custom length, chamfer, end face grinding, polishing and inspection according to the drawing.
Alumina is usually selected for insulating tubes, high-temperature supports and cost-effective rods. Zirconia is selected for tougher rods, shafts, sleeves and smooth wear surfaces.
For ceramic rods and tubes, small dimensional differences often decide whether the part fits. HERUN reviews the drawing and confirms the key dimensions before production.
