DuraKapp™#8 Babbitt is a general purpose, low speed, Lead-based Babbitt that displays good tensile and compression strengths under shock, load, pounding, and vibration. Our unique Precision Microcasting™ process, combined with high purity virgin raw materials, results in the world’s strongest, most ductile Lead-based Babbitt.
DuraKapp™#8 Babbitt meets or exceeds the specifications for ASTM #8 Babbitt —also known as Royal, Grade 8, or QQ-T-390A No. 6 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 8 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
