7200 Angular Contact Ball Bearing (ZrO2)

The 7200 type zirconia (ZrO₂) all-ceramic angular contact ball bearing is a 10×30×9mm international standard precision bearing. It uses yttrium-stabilized zirconia (YSZ) for the inner and outer rings and balls, making it ideal for medium-to-high speed, heavy axial loads, and harsh operating conditions. It combines the corrosion resistance, insulation, and high-temperature resistance of ceramic materials with the axial load-bearing advantages of angular contact bearings.

Core Performance Advantages

● High axial load capacity, strong load adaptability

● All-ceramic corrosion resistance, maintenance-free in harsh environments

● Lightweight + low friction, lower energy consumption at high speeds

● Insulating + non-magnetic, suitable for sensitive working conditions

● High temperature resistance + wear resistance, long service life

● Oil-free self-lubricating compatibility, clean and pollution-free
