Shangshui Tin-based Babbitt Co., Ltd. Bearing Babbitt can be divided into two types according to standards: tin-based bearing alloy and lead-based bearing alloy. Bearing Babbitt has good anti-friction properties. This is because during the initial operation of the machine, after the rotating shaft wears away the extremely thin layer of the soft-phase matrix inside the bearing, the unworn hard-phase particles still play a role in supporting the shaft. As operation continues, interconnected micro-gaps form between the shaft and the bearing. These micro-gaps serve as channels for lubricating oil, maintaining good lubrication between the shaft and the bearing and providing anti-friction effects. This microstructure of Babbitt is quite typical. The composition of most bearing Babbitt alloys is designed to achieve such a microstructure with a soft-phase matrix and uniformly distributed hard-phase particles. Lead-based bearing alloys have lower strength and hardness compared to tin-based bearing alloys and also exhibit poorer corrosion resistance. When customers use Babbitt alloys, they usually choose tin-based bearing alloys. Common grades include ZCHSnSb11-6 (suitable for high-speed steam engines, high-horsepower turbines, compressors, turbine pumps, high-speed internal combustion engines, ball mills, and mineral processing equipment bearings), ZCHSnSb8-4 (suitable for casting high-speed bearings in internal combustion engines), ZCHSnSb4-4 (suitable for turbines, internal combustion engines, and high-speed bearing bushings), ZCHSnSb8-8 (suitable for large machinery bearings and bushings), etc. Lead-based bearing alloys have lower hardness, strength, and toughness compared to tin-based bearing alloys. Common grades include ZCHPbSb16-16-2, ZCHPbSb1-16-1, ZCHPbSb10-6, etc. (suitable for medium-load, light-load, low-speed machinery bushings). Bearing Babbitt is a well-known bearing material, also called white metal due to its white appearance, and it possesses anti-friction characteristics. Bearing Babbitt is suitable for use with relatively low-hardness rotating shafts and is widely used in large marine diesel engines, turbines, alternators, and other mining machinery and large rotating equipment.
