With the development of oil and natural gas on land and sea, the demand for oil refining, ethylene and three major synthetic materials is gradually increasing. This requires a large number of oil and gas pipeline gathering and transmission equipment and large-scale and efficient petrochemical equipment, and focuses on developing large-scale oil exploration and drilling and production equipment in deserts and oceans. Therefore, the annual market demand for sun bearings, mechanical seals and packing static seals for supporting and maintenance of petrochemical equipment will increase greatly.

It is suitable for high-temperature sealed self-aligning roller bearing in harsh environment. The characteristic of this bearing is that there are rubber seals on both sides to ensure the safe operation of the bearing raceway in a dust-free environment and prevent the leakage of lubricating grease. It has the advantages of dust-proof, waterproof, high-temperature and high-pressure resistance and heavy load. It also has open type and high-temperature bearing suitable for specific applications. It can operate continuously and safely under the working conditions of - 40 to + 200 degrees, This is an attractive feature of the sun bearing, which cannot be replaced in many demanding applications.
