Roller bearing race suitable for extreme conditions - is made of steel or ceramic material and operates with self-lubricants cage

摘要

The bearings are suitable for extreme conditions such as high temperatures or operation under vacuum. The bearings have steel races or are made from refractory material or a hard alloy. The material has a high anti-corrosion properties, and may also be made of ceramic material. The cage may include self-lubricating material, which could be based on synthetic components. The bearings are resistant to contact or friction.
