High Temperature Bearings

Bearings operating at high temperatures can be a problem for many reasons, including loss of radial clearance, lubricant degradation, and microstructural changes of ring and rolling element materials resulting in loss of hardness and dimensional instability. These and other problems associated with high operating temperatures can be resolved with specialized heat treatment of rings, internal design considerations and proper material choices.

LILY high temperature bearings are essentially intended for use in environments with extreme temperatures, such as blast furnaces, ceramics industry, bakery and industrial ovens, glass plants, conveyors, dryers, kilns, kiln cars, stokers, soot blowers, oil guns, gypsum board and veneer dryers ...

Alloy Steel Bearings

High temperature resistance, added KLUBER high temperature grease, excellent mechanical properties, low cost, suitable for low speed, high load and difficult environment.

Ceramic Bearings

Corrosion resistant, high temperature, non-magnetic, no lubrication, suitable for low speed, low load and extreme environment.

Ceramic bearing is a basic part of mechanical equipment, because it has many advantages which metal bearings can't compare with, especially in the operating environment of high temperature resistance and high strength. Therefore, there are no substitutes for medical equipment, optical instruments, high-speed machine tools, high-speed motors, and aerospace.

High-temperature ceramic bearings have the ability to withstand temperatures up to 1200 ° C due to the material itself, and the self-lubricating properties are also very good. In the high temperature working environment between 100 ° C and 800 ° C, the high temperature bearing will not produce a large temperature difference, so the bearing won’t become larger in case of the expansion. For the high temperature stability, so in the plastic, steel, and so on, many high-temperature equipment has been applied.

Since the rolling ball density of ceramic is lower than that of steel, the overall weight of the high temperature bearing is much lighter than that of the steel bearing, so the centrifugal force of the outer ring is directly reduced by 40% during the running rotation, so that the bearing life can be made. Greatly extended.

According the principle of thermal expansion and contraction, the high-temperature ceramic bearing is also much smaller than the steel material bearing. Therefore, the high-temperature bearing is also most suitable in the working environment where the bearing clearance is certain and the temperature difference changes more severely and unstablely. Since the ceramic material is not easily deformed when subjected to a force, the work speed can be stably increased, and at the same time, it has high precision.
