Double Pitch K2 Attachment Chain

Double Pitch K2 Attachment Chain is designed for conveyor systems that require attachment points for supporting, positioning, or connecting conveying components. It combines a double-pitch roller chain with K2 attachments and is available in different chain sizes, roller configurations, and attachment arrangements.

Link Plates: Produced from precision-blanked alloy carbon steel to maintain tight pitch tolerances and superior fatigue resistance under cyclic loads.

Pins & Bushings: Carburized and case-hardened to a controlled depth, achieving an effective surface hardness of HRC 58 to 62 to minimize wear elongation.

Rollers: Heat-treated for high impact resistance, ensuring smooth, low-noise engagement with sprockets.

K2 Brackets: Integral-welded or solid-formed extended side plates with dual mounting holes, designed for secure bolted attachments.

 

 

Custom Link Spacing: Tailored attachment intervals configured to your exact conveying layout (e.g., every link, every 2nd link, or irregular spacing).

Specialized Dimensions: Custom hollow pins, special hole diameters, or extended pin configurations upon request.

Surface Treatments: Specialized finishes including protective zinc plating, nickel plating, or heavy-duty rust-preventive oil baths for corrosive or outdoor environments.

 

 

Core Function：
Provides a stable, robust mounting platform via a two-hole symmetric locking design, effectively eliminating structural deflection and loosening under heavy cyclic loads.

Typical Application Scenarios：
Automated logistics sorting and warehousing conveyor lines
Food packaging, carton transport, and pallet feeding machinery
Agricultural equipment and grain handling transport systems
Woodworking and panel manufacturing material feeding lines

Technical Integration Guidance: Attachment spacing can be fully tailored according to your engineering drawings or operational intervals (e.g., configured on every link or spaced across alternating links).

 

 

Load & Series Selection：
Avoid sizing by static weight alone. For applications with frequent start-stops or shock loads, specify Heavy Series models (e.g., C2060H-K2, C2080H-K2) to resist cyclic fatigue.

Attachment Spacing & Off-Center Loads:
K2 dual-hole brackets provide high torsional rigidity. For off-center loading, decrease the attachment interval (e.g., every link) to eliminate structural deflection and fastener loosening.

Environmental Protection:
For corrosive, humid, or food-processing environments, choose nickel-plated finishes or heavy-duty rust-preventive treatments to prevent binding and contamination.

Roller Type (Small vs. Large):
Small Roller: Ideal for standard, compact sliding conveyors.
Large Roller: Reduces friction by rolling instead of sliding. Recommended for long-distance, heavy-load automated logistics to lower energy use and extend wear life.

 

 

Traceable Raw Materials: Fabricated from certified MN40 and high-grade steel, backed by verifiable mill test reports.

Precision Dimensional Inspection: Production lines utilize optical comparators for rigorous pitch and hole diameter verification.

Performance Verification: Destructive tensile strength testing data is available upon request to guarantee compliance with international industry standards.
