Technical characteristic
Babbitt is an antifriction bearing fusible alloy of antimony with tin and copper, or antimony with lead, copper and tin, or an alloy based on aluminum and zinc. The anti-friction property of babbitts is given by the structure of heterogeneous hard particles, which serve as bearing supports encased in a soft lead or tin base. This will give the bearings a uniform fit and run-in to the shafts, low friction and wear resistance. Production - ingots. Marks: B-88, B-16, BN, B-83.
Advantages of B83
- the most popular antifriction alloy;
- higher wear resistance than lead alloy;
- cheaper than babbitt B88;
- Grease friction coefficients 0.28 (without grease), 0.005 (with grease)
- loads: 400 kgf/cm2 (static), 1000 kgf/cm2*s (dynamic), 100 kgf/cm2*s (impact)
- rotation speeds maximum - 60 m/sec;
- 110°C (above zero) heating;
- pouring thicknesses ≥1 mm.
Disadvantages
- low strength (impact loads);
- use in bearings subject to vibration and thinly poured - inadmissible.
