Babbit — an antifriction alloys based on lead or tin, low melting point, used to fill between the friction parts of the mobile nodes. Lagerbuchse antimony, copper, zinc, aluminium and other components. The sliding properties of the alloy gives a special heterogeneous structure — bearing solid granules are enclosed in a soft tin or lead based. This reduces the friction and wear of the contacting parts to a minimum, while the rotating parts quickly work to each other. Lead and tin babbit grades: B-88, B-83, B-16, bn are supplied in the form of ingots.
The most popular brand among the lead babbits — B83. It is wear-resistant and relatively inexpensive alloy remarkably reduces the wear of moving parts, increases the efficiency of the equipment. Brand B83 includes in lead-based solid grains, which relies on the rotating shaft. Fusible base has t° melting point not higher than 320 °C, retains sufficient plasticity to 100 °C. the Maximum speed is 60 km/h. Maximum load: static — 400 kgf/cm2, dynamic — 1000 kg/cm2 sec, shock — 100 kgf/cm2 sec. Maximum operating temperature: +110°C. the Optimum thickness of fill ≥ 1 mm.
Mechanical quality В83
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.
