ASTM-B23 4X Nickel Babbitt
DuraKapp™#4X Nickel Babbitt adds Nickel to the #2 Babbitt matrix to increase tensile and compression strength in high-temperature bearings. Kapp Alloy uses special high-grade virgin raw materials and our proprietary Precision Microcasting™ process to produce the most consistent superior strength Babbitt available.
DuraKapp™#4X Nickel Babbitt lasts longer under severe service because it provides higher strength at higher temperatures without sacrificing ductility. In any bearing application, strength without this crucial ductility leads to bearing failure.
Nickel Babbitt Benefits & Features
- Holds the oil film
- Pours freely and fills all liner crevices
- Anti-frictional
- Cannot cut the shaft
- Resists high temperatures
- High thermal conductivity
Nickel Babbitt Applications
- Compressors and blowers
- Marine and locomotive diesel engines
- Marine bearings
- Reduction gears
- Dredges
- Lumber and cement mills
- Rock and gravel machinery
- Steel mills
- Mining machinery
- Sugar mills
- Paper mills
- Crushers
- Electric railroads
- Clay working machinery
- Paired with KappaTinning™ Compound and Kapp CopperBond™ Flux
