Extreme Environmental Resistance of Ceramic Bearing Solutions
Industrial bearings sometimes fail under extreme thermal stress or chemical media. Our high-quality ceramic bearings provide a reliable solution to such problems. They retain their structural characteristics within the range of -150℃ to 1,400+℃.
Ceramic bearings are also acid, alkali, and water-resistant. This makes them not react with any corrosion or oxidation media like metals. Employing ceramic bearings, you will get stable operation in the harshest vacuum and high-temperature furnace environments.
Maximizing Rotational Speed with Precision Ceramic Bearing
To increase the speed of production, it is required that bearings reduce heat and centrifugal forces. A bearing made from silicon nitride ceramic materials possesses a density of only 3.2 g/cm3. It is only 40% of the density of steel. This reduction in weight lowers centrifugal force during high-speed rotation. A lower friction coefficient reduces energy consumption and heat generation. Using ceramic bearings, your equipment can operate at significantly higher RPMs without thermal seizure or excessive energy loss.
Reducing Maintenance Costs by Durable Ceramic Bearing
The problem of frequent downtimes due to parts replacements can greatly affect the productivity and profitability of your manufacturing operations. The Vickers Hardness level of the ceramic bearing may range from HV1800 and is two times harder compared to conventional metal material. Due to its superior wear resistance, it can provide a service life 5 to 20 times higher than metal materials. Using these ceramic bearings will allow for less maintenance downtime and continuous manufacturing operations.
