DuraKapp™#13 Babbitt is a general purpose, low speed, Lead-based Babbitt with good tensile and compression strengths under shock, load, pounding, and vibration. Kapp Alloy’s unique Precision Microcasting™ process, combined with high purity virgin raw materials, results in the world’s strongest, most ductile Lead-based Babbitts.

 

DuraKapp™#13 meets or exceeds the specifications for ASTM #13 Babbitt —also known as Grade 13. 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 13 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 elevators, hoists, conveyors, hydraulic presses and pumps, mixers, and grinders
  • Paired with KappaTinning™ Compound and Kapp CopperBond™ Flux
