Manufacturing Process Flow of Industrial Sliding Rollers

The manufacturing of high-performance industrial rollers is a complex, multi-stage process demanding precision engineering and rigorous quality control. Our process ensures that each roller meets stringent technical specifications for durability, load capacity, and operational smoothness.

1. Material Selection & Preparation:
   • High-grade alloy steels (e.g., 42CrMo4, 34CrNiMo6) or stainless steels (e.g., 304, 316) are selected based on application-specific requirements for strength, wear, and corrosion resistance.
   • Raw materials are sourced from certified suppliers, undergoing initial metallurgical inspection to verify composition and structural integrity.
2. Forging or Casting (Dependent on Design):
   • For high-stress applications, forging is employed to enhance grain structure, eliminating porosity and improving mechanical properties (tensile strength, fatigue resistance).
   • For complex geometries or larger rollers, precision casting might be used, followed by stress relief annealing.
3. Rough Machining:
   • Initial turning, boring, and milling operations shape the roller to near-net dimensions, removing excess material.
4. Heat Treatment:
   • Processes like hardening, tempering, and carburizing are applied to achieve target surface hardness (e.g., HRC 58-62) and core toughness, significantly extending service life and wear resistance.
   • Stress relief is also performed to prevent distortion during subsequent machining.
5. Precision CNC Machining & Grinding:
   • Utilizing advanced CNC lathes and grinding machines, critical dimensions, bearing seats, and track profiles (U-groove, V-groove, flat) are machined to micron-level tolerances.
   • This ensures optimal fit with sliding door track rollers and minimal friction during operation.
6. Surface Treatment (Optional/Application-Specific):
   • For enhanced corrosion protection or wear resistance, surface treatments like chrome plating, nickel plating, nitriding, or specialized polymer coatings (e.g., PTFE) may be applied.
