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
1. What composition ranges do lead‑ and tin-based Babbitt alloys have?
A: 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.
2. How do Babbitt alloys reduce friction and wear?
A: Their structure embeds hard intermetallic crystals within a softer metal matrix; as it wears, the soft alloy creates lubricant channels and protects shaft surfaces.
3. Which alloy type suits different applications?
A: 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.
4. How does RA Power Solutions ensure quality and consistency?
A: They produce Babbitt alloys to client specs or international standards (ASTM B23), provide metallurgical lab reports, and export grade‑specific ingots globally.
5. Can these bearings be reconditioned (rebabbitted)?
A: Yes, worn Babbitt bearings can be rebound and cast in place; RA Power’s alloy expertise supports efficient rebabbitting and onsite repairs across industries.
