HP400 Upper Thrust Bearing 1057605169 | Bronze Crusher Part

Technical Specifications: Upper Thrust Bearing 1057605169

The upper thrust bearing is a critical component in the Metso HP400 cone crusher, responsible for supporting the vertical crushing force and ensuring smooth rotation of the head assembly. Manufactured using advanced metallurgy, this replacement part provides the necessary anti-friction properties required for high-capacity mining operations.

Core Advantages: Engineered for Extreme Loads

Our aftermarket crusher spares are developed to withstand the rigorous demands of secondary and tertiary crushing. By utilizing superior bronze alloys, we ensure that each upper thrust bearing offers maximum resistance to galling and wear.

• Enhanced Metallurgy: We use high-leaded tin bronze (C93700), which contains 7-11% lead. This creates a self-lubricating matrix that prevents catastrophic failure during short-term oil starvation or high-temperature surges.
• High-Density Casting: Through centrifugal casting, we achieve a grain structure that is 15% denser than traditional sand casting, effectively eliminating subsurface porosity and improving fatigue strength.
• Precision Parallelism: Using 5-axis CNC machining, we maintain strict tolerances on the bearing’s flatness and parallelism, ensuring a uniform distribution of the crushing load across the entire surface area.

Performance Comparison: Newreg vs Standard Spares

Field testing within aggregate plants processing abrasive basalt demonstrates that our wear parts deliver superior economic value:

• Operational Longevity: 20% increase in service life compared to standard bronze replacements.
• Heat Management: Improved thermal conductivity reduces the average return oil temperature by 4-6°C.
• Maintenance Savings: Precision fit reduces the risk of scoring the companion steel thrust plates, extending the replacement cycle of the entire bearing assembly.

Field Diagnosis: Wear Patterns and Maintenance

As experienced crusher part suppliers, we recommend monitoring these indicators to prevent unplanned downtime:

1. Babbitt/Bronze Accumulation: During oil changes, check the magnetic plug and filter for bronze slivers. Significant quantities indicate that the upper thrust bearing is undergoing excessive friction.
2. Lubrication Oil Color: If the oil turns dark or “burnt” quickly, it may be due to localized overheating at the thrust bearing surface caused by uneven wear or improper clearance.
3. Physical Thickness Check: Measure the thickness of the bearing during major overhauls. If the wear exceeds the OEM-recommended limit (typically 10-15% of original thickness), replace the part immediately to avoid damaging the head ball.

Frequently Asked Questions (FAQ)

Q1: Is this 1057605169 bearing compatible with HP300 or HP500 models?
No, this specific part number is sized exclusively for the HP400 cone crusher. Using the wrong size thrust bearing will lead to immediate machine failure due to improper load distribution.

Q2: How does the lead content in your bronze benefit my crusher?
Lead acts as a dry lubricant. In the event of a lubrication system failure, the lead smears across the surface to prevent the bronze and steel from welding together, providing a vital window for emergency shutdown.

Q3: Does Newreg provide material certificates for these wear parts?
Yes. Every shipment includes a chemical composition report (Spectrometer analysis) and a dimensional inspection report to ensure full compliance with mining conglomerate standards.

Expert Tip regarding Installation: When replacing the 1057605169 Upper Thrust Bearing, always inspect the condition of the lower thrust bearing and the head ball. Lubricate the bearing surfaces generously with the specified crusher oil before assembly. Ensure the anti-rotation pins are correctly seated; a loose pin can cause the bearing to spin, resulting in rapid catastrophic failure of the thrust assembly.
