Water lubricated rubber alloy bearing

BTG water lubricated rubber alloy bearing with no pollution, low noise, ultra-low wear, high efficiency, optimize the structure of the shaft, put off easy maintenance, etc. It is not only widely used in the propulsion system of ships, naval vessels and other and other underwater weapons, but also used in the mechanical transmission system of pumps, turbines, washing machines and other industrial equipment. BTG water lubricated rubber alloy bearing with independent intellectual property rights reaches the international leading level. Compared with similar products produced by those companies who have the ability to produce such products in United States and Britain, it has a major breakthrough and innovation in the key technology of the physical and chemical properties of composite rubber bearing, the structural design of elastic hydrodynamic lubrication, the adhesive strength of rubber bearing bush and title dorsal with metal or non-metallic. Products have passed through the ISO9001 quality management system certification, reached U.S. MIL-B-17901 (Ships) Military Standard, got China Classification Society CCS certification, China Classification Society Product Type Approval Certificate and China Classification Society Certification Company UKAS certificate.

From the Lubrication structure, water lubricated rubber alloy bearing lubrication is divided into: the ring groove, circular grooves and spiral grooves; From the structural form, it is divided into: the straight tube, the overall flange, split, splice and slat type, etc..

Product Features:

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

(2)Using 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;

(3)Using 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;

(4)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.

(5) Researching and developing two programs of open and closed water lubrication system for users to choose according to water conditions;

(6) Supporting the use of BTG water lubricated stern shaft seal, it will get more perfect propulsion shafting operating results.
