Comparison of bearing ceramic speed

Comparison of bearing ceramic speed

1. Full ceramic bearings

All-ceramic bearings are bearings made of all-ceramic materials, including outer rings, inner rings and rolling elements. Its main features are excellent wear resistance, corrosion resistance and high temperature performance. bearing full ceramic speed can reach more than 20,000 rpm and is suitable for high-speed, high-temperature, and highly corrosive applications, such as semiconductors, optical fiber communications, medical equipment, high-speed railways and other fields.

2. Hybrid ceramic bearings

Hybrid ceramic bearings are bearings whose inner and outer rings are made of steel or high-temperature alloy materials, and the rolling elements are made of ceramic materials. The main characteristics of hybrid ceramic bearings are high strength, high rigidity, high wear resistance, and low friction coefficient. The bearing hybrid ceramic speed can also reach more than 20,000 rpm, which is suitable for high-speed bearing fields such as machine tools, motors, and wind power.

3. Comparison of applicable scenarios

In terms of application fields, full ceramic bearings are mainly suitable for high-speed, high-temperature, and corrosive conditions, while hybrid ceramic bearings are suitable for high-speed bearing fields such as machine tools, motors, and wind power. In terms of bearing performance, all-ceramic bearings have better wear resistance, corrosion resistance and high-temperature performance, while hybrid ceramic bearings have better strength, rigidity and low friction coefficient, but their rolling elements are easier to use than all-ceramic bearings. Damage occurs.

In general, bearing ceramic speed can reach more than 20,000 rpm, but the applicable scenarios and performance are different. Therefore, when selecting bearings, you need to choose according to the actual application scenarios and requirements.

【Conclusion】

bearing ceramic speed is high-speed bearings with their own characteristics, advantages and disadvantages. In the actual application process, it needs to be selected according to specific scenarios and requirements. Whether it is a full ceramic bearing or a hybrid ceramic bearing, it needs to be kept well lubricated and clean to ensure normal operation and longer service life.
