Ceramic Gear Bushing / Ceramic Shaft Bushing

Kernvorteile

1. Extreme Environment Durability

Made of 99.5% high-purity alumina/zirconia; hardness HRA 88–92; wear resistance 10× higher than stainless steel.

Resists strong acids, Alkalien, and high temperatures up to 1600°C (inert atmosphere); service life extended 3–8×.

2. Leicht & Energy Saving

Density only 3.8–4.0 g/cm³ (≈ 1/2 of steel), reducing inertia and energy consumption for high-speed precision transmission.

3. Self-Lubricating & Maintenance-Free

Surface roughness ≤ Ra 0.2 μm; friction coefficient as low as 0.05–0.1; stable operation without lubrication.

4. Ultrapräzise Bearbeitung

Dimensional accuracy up to ±0.001 mm; tolerance grade ISO h5 (customizable to h3).
