Babbit Bearings: The Unsung Heroes of Industrial Machinery
Babbit Bearings: The Unsung Heroes of Industrial Machinery
In the realm of industrial machinery, where precision and reliability are paramount, babbit bearings stand as unsung heroes, quietly ensuring the smooth operation of countless systems. Whether it's in automotive engines, heavy-duty machinery, or marine applications, babbit bearings play a critical role in reducing friction, minimizing wear, and extending equipment life.
What are Babbitt Bearings?
Babbitt bearings are a type of bearing made from a soft, white metal alloy composed primarily of tin, antimony, and copper. They are typically used in applications where low friction, high load capacity, and low-speed operation are required. The soft metal alloy conforms to the shape of the rotating shaft, providing excellent load distribution and reducing wear.
