Ceramic engineering components
Ceramic parts beyond bearings: dosing pistons, plungers, valve seats, seal rings, guide bushings and nozzles in Al₂O₃, ZrO₂, Si₃N₄, SSiC, SiSiC.
Ceramic components
Not every ceramic part sits in a bearing. We supply ceramic engineering components in their own right — wherever metal reaches its limits through wear, corrosion, temperature or aggressive media.
Engineering components to your specification
Engineering components hardly ever come in fixed catalogue sizes — geometry, tolerances and material follow your application.
How it works: you send us a drawing or a sample together with the operating conditions — temperature, media, pressures, cleaning cycles. We work out the right component and the right material, have it made at our producers and come back with a recommendation. As a sample first if you prefer, then in series.

Materials
Hard, corrosion- and wear-resistant — pistons, cylinders, valve seats, guides.
Tough and wear-resistant, electrically insulating — plungers, valve cones, dosing needles.
Hard, light, resistant to thermal shock — balls, rollers, bearings, guides.
Almost entirely SiC, no free silicon — the better choice above roughly 1,400 °C.
SiC skeleton with 10–20 % free silicon — good for complex geometries and larger parts.
SSiC or SiSiC?
The difference lies in the free silicon and it decides the operating limit. See the direct comparison under SSiC vs. SiSiC.
