professional manufacturer and distributor for special materials bearings
ZrO2 Angular Contact Ball Bearing: Handles combined radial/axial loads. High hardness, corrosion resistance, low friction for high-performance applications.
High-precision ZrO2 ceramic bearings excel in extreme conditions, offering:
Material: ZrO2 (Yttria-stabilized) for corrosion/wear resistance, low density, and electrical insulation.
Design: 15°–40° contact angles for combined radial/axial loads, high-speed capability (up to 1.5× steel bearings).
Performance: Operates at -200°C to +600°C, minimal thermal expansion, and no lubrication needed in vacuum.
Applications: Aerospace, medical, semiconductor, and high-speed spindles.
