Graphite Support Pillars & Spacers
Fine-grained isostatic graphite support pillars, columns and spacers for multi-layer fixture assemblies. Machined to close tolerances from TOYO TANSO grades. Available in cylindrical, hexagonal and custom threaded profiles.
Graphite Support Pillars and Spacers are precision-machined components that separate charge trays and fixture frames within multi-layer vacuum furnace loading assemblies. They transfer vertical load between layers while withstanding repeated thermal cycling to 3000ยฐC without dimensional creep.
Manufactured from fine-grained isostatic graphite (TOYO TANSO authorised grades), pillars are machinable to close tolerances and can be supplied with threaded ends, stepped shoulders, or precision-ground flat faces depending on the fixture design. Hexagonal profiles offer improved angular stability over cylindrical versions when used in loose-fit sockets.
Standard diameters from 10 mm to 100 mm and lengths from 20 mm to 500 mm; custom sizes on request. Packaged in matched sets for complete fixture assemblies.
