Composition of the material: Powder antifriction material on the base of bronze OCS555 with additives of hard lubricants such as graphite, disulphide of molybdenum, etc.
Main characteristics of the material:
- ● Hardness – 550-640 MPa;
- ● Tensile strength – 220-240 MPa;
- ● Impact strength – 25-30 kj/m2;
- ● Friction coefficient in oil – 0,004-0,015.
Type and characteristics of the products: radial and face bearings of gear-type pumps like НШ8-НШ50 ensure
the service life of pumps up to 10 000 - 12 000 hours when working pressure is up to 30 MPa.
An output mastery of developed products: An output of the production is mastered at O.V.Roman Powder Metallurgy Institute and Molodechno Powder Metallurgy Plant.
Novelty: the copyright certificate is received.
