Leaf Chains-AL Series Product Introduction

Core Design & Construction

• Light - Duty Plate Design: Link plates and pins are dimensionally consistent with standard ANSI roller chains of the same pitch, with the same plate thickness and pin diameter as ANSI roller chains, balancing structural simplicity and basic load - bearing performance.

• Reliable Assembly: Outer links are press - fitted and riveted to pins to prevent rotation and ensure connection stability. Inner links are slip - fitted to pins for smooth articulation, and the number of link plates can be adjusted based on lacing configurations (e.g., 2×2, 4×4, 6×6).

• Material & Heat Treatment: Usually made of high - quality carbon steel (like 1045 steel) with appropriate heat treatment (quenching and tempering), guaranteeing sufficient tensile strength and wear resistance for light - duty working conditions.

Performance Advantages

1. Cost - Effective: Leveraging standard ANSI roller chain components for production, AL Series Leaf Chains reduce manufacturing costs, making them an economical choice for light - duty applications.

2. Space - Saving: The compact structure without rollers or bushings enables easy installation in limited - space equipment, such as small - size machine tools and compact lifting mechanisms.

3. Good Flexibility: The slip - fit design of inner links ensures smooth articulation, suitable for applications with frequent small - angle bending movements.

4. Easy Interchangeability: Consistent with ANSI roller chain dimensions, facilitating replacement and maintenance, and compatible with standard sprockets and sheaves designed for ANSI chains.

Applications

• Counterweight systems in small - and medium - sized machine tools

• Light - load lifting mechanisms in packaging and printing machinery

• Traction components in small - scale aerial work platforms and textile equipment

• Auxiliary lifting devices in small forklifts and material - handling carts

Accessories & Customization

• Standard Accessories: Various connecting links, end joints, and clevises are available to meet different installation and connection requirements, ensuring simple and rapid assembly.

• Custom Solutions: Customizable lacing configurations (e.g., 2×3, 3×4) and surface treatments (black oxide, zinc plating) to adapt to specific environmental and load needs.

Installation & Maintenance Tips

1. Ensure proper alignment of sprockets/sheaves to avoid uneven wear of link plates and pins.

2. Use suitable lubricants to minimize friction and extend the service life of the chain.

3. Regularly inspect the chain for signs of wear, deformation, or loose pins, and replace worn components promptly.

4. Do not use AL Series Leaf Chains in heavy - duty or shock - load scenarios beyond their load - bearing capacity to prevent chain failure.
