Babbit B83 - Super Tough babbit
Characteristics of babbit B83
Babbit — antifriction bearing low-melting alloy of antimony with tin and copper, or — antimony with lead, copper and tin, or — an alloy based on aluminum and zinc. The antifriction property is given to them by the structure of heterogeneous solid particles, which serve as a support for bearings encased in a soft base of lead or tin. This will give uniform contact and wearability of bearings to the shafts, small friction and wear resistance. Manufacturing — pigs. Brands: B-88, B-16, BN, B-83.
Advantages of Babbit B83
- The most popular antifriction alloys;
- The index of wear resistance is higher than that of the lead alloy;
- Cheaper babbita B88;
- Coefficients of friction of lubricant 0,28 (without lubricant), 0,005 (with lubrication);
- Loads: 400 kgf / cm2 (static), 1000 kgf / cm2 * s (dynamic), 100 kgf / cm2 * s (percussion);
- The maximum rotational speed is 60 m / sec;
- Heating 110 ° C (above zero);
- Fill thickness ≥1 mm.
Disadvantages of Babbit B83
- Low strength (impact loads);
- Application in bearings subject to vibration and filled with a thin layer — is unacceptable.
