In selecting the proper type of Babbitt for a particular job and application there are many factors to take into consideration, the most important of which are as follows:
- Surface speed of the SHAFT (RPM)
- Load bearing is required to carry
The following points must also be taken into consideration:
- Continuity of service
- Bonding possibilities
- Cooling facilities
- Lubrication
- Cleanliness
- Attention is given to the bearings in question

FAQs
Tin-based Babbitts typically contain ~80–92% tin, 7–11% antimony, and 3–6% copper; lead-based ones replace tin with ~70–80% lead plus similar antimony and copper levels .
Their structure embeds hard intermetallic crystals within a softer metal matrix; as it wears, the soft alloy creates lubricant channels and protects shaft surfaces.
Use tin-heavy Babbitt (high-tin) for high-speed, heavy-duty environments like turbines. Choose lead-based alloys for lower-load, cost-effective uses and enhanced corrosion resistance .
They produce Babbitt alloys to client specs or international standards (ASTM B23), provide metallurgical lab reports, and export grade‑specific ingots globally
Yes, worn Babbitt bearings can be rebound and cast in place; RA Power’s alloy expertise supports efficient rebabbitting and onsite repairs across industries.
