Babbitt Bearings

We repair and rebuild all types of Thrust, Sliding, and Radial Babbitt Bearings:

Babbitt Bearing reverse engineered scanned using laser scanner technology then modeled using specialized software to create surfaces and three dimensionally modeled for casting and machining.

turbine babbitt bearing spun cast and machined. fully inspected three dimensionally with laser measurement. Babbitted bearing thrust pads cast and machined.

 Centrifugally casting babbitt bearings & Ultrasonic testing of bond.

Large babbitt bearing being centrifugally cast. Centrifugally casting of hydroelectric turbine babbitt bearing with 54″ journal.

Ultrasonic testing of thrust bearing out of large raw mill gear box.

Full in house Pouring, Machining, and Inspection means rapid turn around.

Mill babbitt bearing rebuild. Bearings are measured on arrival and housing fits verified. Bearing cast to provided maximum bond strength and no proisity. Machined to size, inspected, and packaged for shipping.

Types Of Babbitt Commonly used

Babbitt has good load carrying capacity between 800 PSI and 1500 PSI

Maximum operating temperature for Babbitt is 300º F. In motors 180º F to 190º F 
is considered running hot. Some turbine applications run as high as 225° F.
Many technicians however, will set the alarm at 185º F and trip at 205º F.

Melting temperature for common Babbitt varies from 350º F to 475º F
bullet Special bonding techniques are required to metallurgically bond Babbitt
to metal.

Tin based Babbitt (#2) is approximately 89% tin with the remainder 
being antimony and copper. 

The hardness of this alloy gives excellent load-carrying characteristics. 
Lead based Babbitt (#7) is 75% or more lead. Conventional lead- base Babbitt
contains antimony and tin, which greatly increase the strength and hardness 
of lead. This alloy is fully adequate for lower loads and moderate temperatures.
