Technical characteristics
Babbit — an antifriction bearing fusible alloy of antimony with tin and copper, or of antimony, lead, copper and tin, or an alloy based on aluminum and zinc. Antifriction property of the babbit gives structure heterogenous — solid particles which serve as supports for bearings, enclosed in a soft core of lead or tin. This will give a uniform fit and pererabatyvaemogo bearings to shafts, small friction and wear resistance. Manufacturer — pig. Brand: B-88, B-16, bn, B-83.
Dignity B83
- the most popular of the antifriction alloy;
- higher than lead alloy, abrasion resistance;
- cheaper babbit B88;
- the coefficients of friction of 0.28 lubricant (no lubricant) 0,005 (with lubrication);
- load: 400 kgf/cm2 (static), 1000 kgf/cm2*sec (dynamic), 100 kgf/cm2*sec (drums);
- speeds the maximum is 60 km/h;
- heating of 110 °C (above zero);
- fills thickness ≥1 mm.
Disadvantages
- low strength (a shock load);
- use in bearings subject to vibration and filled with a thin layer is unacceptable.
