AC6733 Aluminum Oxide Bearing Balls

Aluminum Oxide Bearing Balls Description

Aluminum Oxide Bearing Balls are high-performance ceramic components engineered for extreme environments. Resistant to most corrosive chemicals-except hydrochloric acid, hydrofluoric acid, and strong alkalis-these balls are non-porous, lightweight, and harder than steel. With exceptionally low friction and the ability to spin at higher speeds than traditional steel balls, they are ideal for high-speed, high-precision, and corrosion-resistant bearing applications across aerospace, chemical, and industrial sectors.

Aluminum Oxide Bearing Balls Applications

1. High-Speed Bearings

Due to their low friction and high hardness, Al₂O₃ balls are ideal for precision, high-RPM bearing systems, including in turbines, spindles, and dental tools.

2. Chemical and Corrosive Environments

Thanks to their excellent chemical resistance, they are widely used in chemical processing equipment, fluid pumps, and valves handling corrosive or reactive fluids.
