oilless thrust washer

Industrial Axial Force Management

Zero-maintenance load support

Extreme Load Architecture

The graphite-embedded 650# alloy withstands 950MPa axial stress in this thrust bearing washer, outperforming traditional roller thrust bearing units prone to brinelling. Documented outcomes in steel coilers:

• Stable μ=0.08 friction under 1,100°C radiant heat
• 0.005mm wear after 5M cycles at 65rpm
• Eliminates ball thrust bearing failures in 8,000-ton press ram systems
  Foundry crane installations report 19-year lifespans with this solution versus 3-year greased thrust bearing washer alternatives.

Thermal Neutrality Control

Coefficient-matched graphite maintains ±0.02mm flatness from -55°C to 380°C. Glass tempering line validations confirm:

• Zero thermal warp during 700°C→40°C quenching cycles
• 38% lower startup torque versus oil-lubricated roller thrust bearing assemblies
• No outgassing in vacuum chamber applications
  Aerospace flap actuators achieve FAA-compliant operation using this ball thrust bearing replacement for hypersonic thermal regimes.
