TIAN LONG, being a kind of efficiently modified polyer material, is of excellent characteristics such as high strength, wear resistant and self-lubricating,especially in water,and so is paritcularly appropriate for using as stern tube bearings and rudder bearings on ships and those for various water pumps and so on. The typical merits of TIANLONG are as follows:

 1.Long life:
  The application life especially in water is usually much longer than most conventional materials such as bronze, babbitt nylon, PTFE, lignum vitae,laminated materials etc.

  2.Easy fabricating and quick instrallation:
  TIANLONG is supplied in semi-finished product, and is installed by freezing and shrinking for interference fit.

  3.High compression and impact strength:
  The material can bear the stress concentration action due to the slight bending of the axis,and may spread the stress to a much larger atea.

  4.Wide scope of application:
  The material can be used in sea water,dirty water and in oils as beatings and bushings.It can also be used as guide-ways,gasket thrust washers, supporting roller, sliding plates, sealings and so on in various mechanical and ealectrical industries.
