Belzona 1131 (Bearing Metal)

Belzona 1131 (Bearing Metal) is a high-performance, two-part epoxy-based composite specifically designed for the repair and protection of worn or damaged bearing surfaces, particularly in heavy machinery and equipment. It is ideal for restoring bearings and shaft journals to their original dimensions, ensuring extended service life and reduced downtime.

Key Features

1. High Wear Resistance:
   • Excellent resistance to wear and abrasion, making it ideal for high-stress applications such as bearings and rotating equipment.
2. Good Adhesion:
   • Strong adhesion to metals, including cast iron, steel, and non-ferrous alloys, as well as other substrates.
3. Easy to Apply:
   • Simple to mix and apply, even for large and complex bearing surfaces.
4. Durability:
   • Resists corrosion, cavitation, and chemical attack, ensuring long-lasting protection.
5. Machinable:
   • Once cured, the material can be machined to the desired finish, allowing for precise dimensional restoration.
6. Temperature Resistance:
   • Can withstand operating temperatures up to 120°C (248°F), with intermittent exposure up to 150°C (302°F).

Applications

• Bearing Repairs:
  • Ideal for repairing worn or damaged bearing surfaces in motors, pumps, compressors, and other machinery.
• Shaft Journal Repairs:
  • Used for rebuilding worn shaft journals and restoring them to their original dimensions.
• Bushing and Sleeves:
  • Rebuilds and reconditions worn bushings and sleeves, restoring them to full functionality.
• Industrial Equipment:
  • Protects and restores critical equipment components exposed to heavy wear, pressure, and environmental factors.

How to Use

1. Surface Preparation:
   • Thoroughly clean and degrease the surface to remove contaminants such as oils, grease, and dirt. Abrade the surface for better bonding.
2. Mixing:
   • Mix the two components (Part A and Part B) in the specified ratio until a uniform color is achieved.
3. Application:
   • Apply the mixed compound directly to the bearing surface or shaft journal, ensuring full coverage. Smooth the material for an even finish.
4. Curing:
   • Allow the material to cure at room temperature. Full mechanical properties are typically reached within 24-48 hours.
5. Machining:
   • Once cured, the material can be machined to restore the original bearing dimensions.
