Ceramic angular contact bearings are high-precision bearings designed for combined radial and axial loads. They are available in hybrid (stainless steel rings + Si₃N₄ ceramic balls) and full ceramic (ZrO₂/Si₃N₄ rings + ceramic balls) designs. With contact angles of 15°/25°/30°/40°, they offer high speed, high stiffness, low friction, corrosion resistance, electrical insulation, and thermal stability. Ideal for precision spindles, aerospace, dental equipment, vacuum/chemical systems, and high-speed motors.
