-Application: Heavy-Duty Conveyor Systems for Automotive Manufacturing (EV Transfer)

-Compatibility: Interchangeable with ISO 12B-2/12B-3 Roller Chains

2. Key Performance Parameters

Mechanical Properties

-Pitch: 19.05 mm (12B Standard)

-Breaking Load: ≥86.79 kN

-Working Load:

12B-2 Configuration: 1,000 kg (Standard Automotive)

12B-3 Configuration: 1,800 kg (EV Application)

-Elongation Tolerance: ≤0.5% over 16 links (Measured at 304.8mm per 16 links)

-Lateral Movement: ≤0.1mm (Superior rigidity vs. competitors)

Material Composition

-Rollers: Precision-ground nickel plated alloy steel, hardened to 55-60 HRC

-Bushings: High-density sintered bronze with embedded lubricant (Maintenance-free)

-Pins: Chemically nickel-plated, wear-resistant coating

-Side Plates: Cold-forged carbon steel, heat-treated for fatigue resistance

3. Performance Advantages

Lubrication & Wear Resistance

-Self-Lubricating Design: Embedded lubricant in sinter bushings ensures consistent oil film (No external lubrication required).

-Low Friction: 15-20% lower Newton-meter force vs. competitors (Tested under 1,800 kg load).

-Wear Life:

35x longer lifespan vs. standard chains (ISO 12B baseline).

Zero measurable stretch after 3-day continuous 2.4-ton load test.

Operational Efficiency

-Noise Reduction: ≤65 dB (Tested on Nylon/IRP wear strips; 30% quieter than competitors).

-Compatibility: Optimized for high-density polyethylene (HDPE) and nylon wear strips.

-Energy Savings: Reduced drive motor power demand due to low friction.

Durability

-Corrosion Resistance: Nickel-plated pins and sealed joints for harsh environments.

-Lateral Stability: Minimal play between side plates (≤0.05mm deviation under load).

5. Recommended Applications

-Automotive Assembly: EV transfer systems, robotic skid conveyors.

-Heavy Industry: Material handling, palletized load conveyors (≤2.5 tons).

-Critical Environments: Cleanrooms, food processing (Dry lubrication eliminates contamination).

6. Maintenance Guidelines

-Inspection Interval: Biweekly elongation checks (Tsubaki gauge recommended).

-Lubrication: None required (Embedded lubricant lifespan matches chain wear life).

7. Certifications & Compliance

-Quality Standards: ISO 9001, ISO 14001, ISO 45001.

-Safety Compliance: DIN 8187/8188 (12B Roller Chain Standards).
