Water Lubricated Rubber Alloy Bearings

BTG water lubricated rubber alloy bearing is invented by Professor Wang Jiaxu, Chongqing University and produced by Chongqing Benteng Technology Co., Ltd.It has clean, ultra-low noise, ultra-low wear, optimize the structure of the shaft, extending the life of equipment, assembly and disassembly easy, etc. other advantages and it`s an eco-friendly high-tech products in the international leading level with independent intellectual property rights.

BTG water lubricated rubber alloy bearings can be widely used in a variety of propulsion shafting system, such as ships, warships, submarines and other underwater weapons, and various pumps, oil drilling, mechanical drive turbines, washing machines or other industrial equipment.

The product is highly competitive in the international market for its high performance and low cost. In order to meet growing market demand, Chongqing Benteng Technology Co., Ltd. established BTG water lubricated rubber alloy bearing production base, and has achieved ISO 9001 quality management system certification and "water lubricated rubber alloy bearing type approval letter".BTG have been exported to dozens of countries, such as the United States, the United Kingdom, the Netherlands, Sweden, New Zealand and other European countries and Malaysia, Indonesia, Brazil, Thailand, Egypt, the United Arab Emirates. Our company takes "develop high technology & industrialization" as our aim, and we always unswervingly take the road of technological innovation, to ensure the development of a variety of products to be the best choice for domestic and foreign customers.

Product Features :

Use self-developed new polymer composite materials, particularly suitable for a variety of water used for lubrication medium conditions;

Use self-developed multi-functional digital control precision plastic molding process, to achieve more dense rubber layer in microstructure, and to ensure that the glue has great carrying capacity but also with certain resilience;

Use self-developed adhesive with advanced bonding technology, ensure that the layer is firmly bonded with various metallic or non-metallic sleeve, and never fall off;

Optimized structure combines elastic hydrodynamic lubrication multi curve with arc lubricating groove, both to ensure the carrying capacity of the water film, but also has good sand, impurities excretion;

Develop open and closed water lubrication systems two options for users to choose according to water conditions;

Support the use of BTG Benteng water lubricated stern shaft sealing device, propulsion shafting system will make more perfect operating results.
