The problem: Optimum temperature resistance at both high and low temperatures, guaranteed safety, reliable sealing materials, a low price and a short delivery time: these requirements for roller bearings used in high-temperature applications have not been met all at once until now. It was truly challenging to search for a solution, and things usually ended with expensive, hard-to-deliver products or special bearings.
The solution: Xtemp series ABEG® roller bearings. For this purpose, proven Supra and Premium class bearing technology with the most suitable materials and modifications were identified and tested on the test rig under the harshest conditions in order to find particularly high-performance combinations for applications at both high and low temperatures. The materials most suited for the specific application, consisting of roller bearing steel, ceramics or PEEK, paired with a sophisticated design, adapted production processes, specifically selected sealing materials and cover materials and grease variants, guarantee optimum temperature resistance, lower maintenance efforts, and longer service lives. Furthermore, customers are no longer forced to acquire costly product properties that they don’t even need with standard premium bearings.
|>1000 °C||SiC ceramic (silicon carbide)|

|500 °C||Si3N4 ceramic|
|up to 450 °C||Stainless steel|

Rough operating conditions call for good seals and covers that protect the interior of the bearing. In addition to high temperature resistance, highly effective sealing is also required. For this reason, Xtemp series bearings are equipped with the sealing and cover materials most suitable for the specific application.
|base material||Designation||Temperature range|
|acrylonitrile butadiene rubber||NBR||-40 °C to 120 °C|
|silicone rubber methyl polysiloxane||MQ/PMQ/VMQ/PVMP||-70 °C to 200 °C|
|hydrogenated acrylonitrile butadiene rubber||HNBR/NEM||-30 °C to 160 °C|
|fluorine rubber (Viton)||FPM/FKM||-25 °C to 200 °C|
|acrylate rubber||ACM||-17 °C to 170 °C|
From 200 °C, Z covers made of cold-rolled steel sheet or PEEK are used.
