Chongqing research and development ship water-running rubber alloy bearing

Chongqing University and Chongqing Pentium Transmission Technology Co., Ltd. newly developed a new type of ship water-lubricated rubber alloy bearing, which filled the domestic gap. At present, relevant parties are cooperating with the relevant manufacturers of ship parts and components in the city to push this achievement to industrialization as soon as possible.

It is understood that this kind of bearing is a key component that connects the traditional system of the ship. It is widely used in the position of propeller and tail wing, and direct command affects the navigation of the ship. Ordinary bearings are made of metal materials such as iron and copper. Therefore, lubricating oil is required as a medium during operation to reduce the friction between the bearing and the power system, and to effectively protect the surface of the metal parts. The normal operation of the ship's power system is affected by the rusting of the components.

Through unremitting efforts in recent years, the project team selected rubber as a substitute for metal alloy materials, and through chemical means, put a "nano coat" on the rubber bearing, its strength is equivalent to that of metal alloy, technical performance index It has reached the military standard for US ships. This marine rear-drive rubber alloy bearing breaks the traditional mode of using mineral oil as a lubricating medium, so that ordinary natural water can achieve bearing lubrication and save oil cost.

“The most important thing is that through the processing and technical development of the bearing surface, the rubber bearing of this layer of “nano coat” can be used to achieve natural lubrication with water.” The person in charge of the project said that using this technology, When manufacturing bearings, it will save 70% of the cost of metal materials, and can also save 100% of the cost of using lubricants. The relevant person in charge of the Municipal Science and Technology Commission said that the new type of water-lubricated rubber alloy bearing technology for ships is the first in China.

What makes Stainless Steel Ratchet Buckles the first-choice for high-end users?

It's the anti-rust advantage as well as its good looking surface.

You don't have to worry about the buckle goes rust even you use it at the sea shore.

It's higher in price though,however everyone who's using it thinks it's worth trying.
