High Temperature Ceramic Bearings

Ceramic is the perfect material for any application seeking to achieve higher rpm s reduce overall weight or for extremely harsh environments where high temperatures and corrosive substances are present.

High temperature ceramic bearings.

High temperature ceramic bearings are also widely used in high speed machine tools high speed motors metallurgy aerospace aerospace and other fields. Can operate at higher. Our bearings are available in a wide range of sizes and configurations in both solid and fully split construction. Extremely resilient to corrosion and foreign particles.

In addition to being excellent electric insulators hybrid bearings have a higher speed capability and will provide longer service life than all steel bearings in most applications. High temperature ceramic bearings full ceramic bearings provide corrosion thermal and electrical resistance with good load and speed capacity in a light weight compact size with service up to 2192 f that can operate without lubrication that would degrade under extreme conditions. Skf high temperature bearings and bearing units are designed to deliver increased reliability reduced complexity and decreased environmental impact in operating temperatures up to 350 c 660 f making these products very suitable for applications in kiln trucks roller hearth furnaces and bakeries. Ceramic bearings are precisely because of the characteristics of ceramic materials so compared to ordinary steel bearings ceramics ball bearings are suitable for high temperatures.

Silicon nitride sin4 alumina oxide al2o3 zirconia oxide zro2 silicon carbide sic. High temperature carbon sleeve composite sleeve hydrodynamic and ball bearings since 2001. Ordinary steel bearings its temperature is 120 c it is a high temperature bearing its temperature can only reach 180 c. For bearings with service up to 2192 f.

Because skf high temperature bearings correspond to the iso dimensions of grease lubricated bearings production efficiencies and cost savings can be realized with a simple change to the. Usually the material weakens above a certain temperature and the bearing can no longer handle any meaningful load or speed. Ceramic bearings are also harder than steel bearings and therefore are more durable. Advantages of longlife hightemp.

When used in combination with high quality lubricants these bearings provide you with a solution which has an extremely long lifetime in high temperature operating environments. Can operate at temperatures of up to 350 c. Ceramic balls also create a lower degree of wear on the races. Full ceramic bearings have races and balls that are made entirely of ceramic material and are superior to common steel bearings in many ways.

The smoother surface of the ceramics also significantly reduces the risk of bearing seizure with little to no lubrication. 4 8 times longer lifetime. No damage under extreme temperature changes. All bearings have temperature limits.

Mrc hybrid ceramic ball bearings use a combination of traditional 52100 steel rings precision matched with silicon nitride ceramic balls. Provided a suitable lubricant is used chrome steel bearings can handle temperatures up to 150 c while 440 grade stainless steel bearings can be used at temperatures of up to 300 c full ceramic bearings can be used at temperatures of up to 1000 c. Insert full ceramic bearings full ceramic insert bearings can continue to operate under extremely high temperatures and are capable of operating up to 1800 deg. Ceramic is much lighter than steel and many bearings are 1 3 the weight of a comparable steel bearing.
