DuraKapp™#15 Babbitt is a general purpose, low speed, Lead-based Babbitt with good tensile and compression strengths under shock and load with little lubrication. Kapp Alloy’s unique Precision Microcasting™ process, combined with high purity virgin raw materials, results in the world’s strongest, most ductile Lead-based Babbitt.

 

DuraKapp™#15 Babbitt meets or exceeds the specifications for ASTM #15 Babbitt —also known as Durite, Grade 15, or QQ-T-390A No. 10 Babbitt. We back all of our products with a 100% satisfaction guarantee or your money back.

Applications

  • Slower speed, heavy load and pressure settings in small or large bearings
  • Especially useful in older equipment to conform to small consistent  imperfections in shafts and shells
  • Refurbishing Grade 15 bearings in heavy load and pressure applications in low speed shafts and drives
  • Found in drives and equipment with little lubrication or maintenance
  • Older slower speed shafts, drives, motors, and engines
  • Found in material handling and mixing equipment – pulverizers, mixers, screeners, grinders, and woodworking machinery (saw mills, tables, and shapers)
  • Paired with KappaTinning™ Compound and Kapp CopperBond™ Flux
