New Material Sector Star, Polymer Bearings Taking Place of Ceramic Bearings in the Underwater Work Environment
We know that almost all types of boats, whether they are large yachts, passenger ships or cargo ships, are placed on the drive shaft. Therefore a high-quality drive shaft arrangement plays a significant role in the overall operation of the vessel. Earlier we were using conventional shaft bearings on our ships. These bearings caused problems for people because they often needed regular maintenance and lubrication. In order to solve this problem, the new material sector star – polymer bearings, with its unique low-friction self-lubricating properties, and gradually into the public field of vision.
Polymer bearings are plastic bearings that we often call them. They have good self-lubricating properties and are suitable for use in a variety of environments, such as dry outdoor or wet sea water. At this point, they are comparable to ceramic bearings, especially in seawater. Bearings do not require grease lubrication, in line with the EPA’s unified national emission standards, also these are environmentally friendly bearings products. Polymer bearings have low friction properties, which is necessary for deck safety, which ensures that mooring lines are not damaged under tension.
Polymer bearing have a range size, and are able to meet the needs of different types of vessels. Of course, this is not limited to the use of ships, all underwater operation of the instrument is also the scope of its application. Polymer bearings almost no deformation in the water, the service life is also ten times the ordinary shaft bearings. In terms of the use on ships, the current polymer bearings is ideal bearings which have been certified by a number of classification societies, including China Classification Society, Det Norske Veritas, Lloyd’s Register, Korea Classification Society.
