Description
Mechanical Zinc Plating Bearing Disc Spring: Advanced Wear-Resistant Solution for Heavy-Duty Industrial Bearing Assemblies
Product Overview
Our Mechanical Zinc Plating Bearing Preload Disc Spring is engineered as a specialized wear-resistant solution for demanding industrial environments where bearing assemblies operate under extreme conditions.
Operating Environment
Designed for heavy machinery operating under extreme conditions including:
  • High friction environments (coefficient up to 0.6)
  • Abrasive particle contamination (up to 200 mg/m³)
  • Cyclic loading (10⁵ cycles/hour)
Technical Specifications
Feature Specification
Design Types Grooved (high-speed up to 8,000 RPM) and Grooveless (static loads up to 1200 kN)
Precision Tolerance class IT6 with uniform load distribution (±3% variance)
Load Efficiency 4.2x force output at equivalent displacement
Surface Treatment Mechanical zinc plating (8-12μm thickness, ASTM B633 Type II)
Wear Resistance Taber abrasion index ≤0.03 mg/cycle
Corrosion Protection 500 hours neutral salt spray per ASTM B117
Material & Construction
Constructed from premium alloys with enhanced durability:
  • 65Mn alloy with tensile strength 980-1180 MPa
  • 60Si2MnA alloy with yield strength ≥1274 MPa
  • Shot peening treatment for surface hardness HV 450-500
Performance Advantage: Maintains 95% of initial preload force after 10⁶ fatigue cycles, extending service life by 60% in demanding applications.
Industrial Applications
Ideal for heavy industrial bearings in:
  • Dusty forging presses
  • Mining conveyor systems
  • Construction equipment bearings
  • Steel rolling mills
  • Cement kilns
  • Offshore drilling rigs
