Sliding Bearings

Sliding Bearings

Ceramic sliding bearings are load-bearing components that operate under relative motion between surfaces—either oscillating or continuously sliding—without the use of rolling elements. Unlike traditional ball or roller bearings, sliding bearings handle axial or radial loads through surface contact, and when constructed from advanced ceramics, they deliver outstanding performance in harsh operating conditions. They are ideal for use in applications where lubrication is minimal or intermittent, temperatures are high, and media is corrosive or abrasive.

Material Diversity

Yttria-Stabilized Zirconia (YSZ) | Zirconia Toughened Alumina (ZTA) | Alumina (Al₂O₃)

Each component is isostatically pressed and sintered, followed by precision grinding and lapping to ensure ultra-low surface roughness and tight dimensional tolerances.
