This tin Babbitt in comparison with the analogues of higher sliding quality indicators of pererabatyvaemogo, resistance to wear and corrosion, excellent thermal conductivity. In soft substrate included solid granules with the following characteristics: hardness HB 13−32, high ductility at 100 °C (HB 9−24). Recommended thickness of the fill bolee1 mm, t° fill ≤ 420 °C.

Babbitt alloys are not resistant to shock loads and vibration, which often complicates the work of the mobile nodes. Small strength allows you to operate only the babbit in the bearings with a solid housing on the basis of steel or non-ferrous alloys. B88 is one of the most expensive.
