From standard geometries to fully custom shapes, CeramTec supplies piezoceramic components engineered for your application. Our engineering team supports you from the first design discussion through development and testing, so that each component matches your performance and integration requirements.
Custom shapes are available. Not every combination of thickness and lateral dimensions can be produced, so our engineers will confirm feasibility for your specific design. A list of standard sizes is available on request.
Tailored to Meet Your Specific Design and Application Needs

Piezoceramic Components
Standard Mechanical Tolerances
| Parameter | Tolerance |
|---|---|
| Outside diameter | ±0.15 mm (±0.006") |
| Inner diameter | ±0.15 mm (±0.006") |
| Length & width | ±0.15 mm (±0.006") |
| Thickness | ±0.05 mm (±0.002") |
| Squareness (edge to face) | Within 0.15° |
| Concentricity | ±0.2 mm (±0.08") TIR |
| Surface flatness (lapped parts) | ±12 μm (0.012 mm / ±0.0005") |
| Surface flatness (large sliced parts) | ±15 μm (0.015 mm / ±0.0006") |
| Parallelism (lapped parts) | ±12 μm (0.012 mm / ±0.0006") |
| Parallelism (large sliced parts) | ±60 μm (0.06 mm / ±0.0024") |
| Surface finish (Ra) | ±3 μm (0.003 mm) |
Tighter tolerances are achievable on request, for example concentricity within 0.13 mm (0.005") TIR and surface finish Ra within 1.6 µm (63 µin). For large parts, achievable tolerances must be confirmed before ordering.
