Tail pipe rubber bearing

The company adopts integral injection pressure process to produce according to GB769-86 standard. Bearing diameter 40mm-300mm.

In 1984, the Chinese government promulgated the "Law of the People's Republic of China on the Prevention and Control of Water Pollution". According to the regulations and regulations formulated by this law, it is strictly forbidden for any ship to discharge oil, oily mixture and other harmful substances. At present, all kinds of motor ships sailing in the Yangtze River leak oil, and nearly 1000 tons of oil are discharged into the Yangtze River every year. Rubber bearings are used on board, and oil lubrication is changed to water lubrication, so that the pollution of oil leakage can be completely solved.

Selection Principles of Design Parameters of Stern Tube Rubber Bearing

1. The specific pressure (MPa) of the bearing is commonly used as P=W/DL

In the formula: W~bearing load N;

D~ journal diameter M;

L~bearing length M;

2. Bearing installation clearance

3. Lubricating cooling water device

4. The thickness of the rubber layer of the tailpipe rubber bearing
