ANSI attachment chain is standard ANSI roller chain with attachment plates or extended pins in place of certain link plates, used to carry buckets, slats, crossrods, or other conveyed components at fixed intervals. LILY Bearing stocks attachment chain and individual attachment links in trade sizes #35 through #80 (plus double-pitch equivalents C2040–C2080H), in steel construction, single-strand only, in tab-style (A-1, K-1, SA-1, SK-1) and pin-style (D-1, D-3) attachment configurations.

Shop ANSI Attachment Chain by Type

This category covers three distinct product forms: individual attachment links you add into your own existing standard chain, complete pre-built attachment chain, and single connecting links used to extend or repair an existing attachment chain run.

Attachment Links (Add to Your Existing Chain)

These are individual links, not full chain — they replace a standard link at set intervals in a chain you already own, to create attachment points without buying a whole new chain.

ANSI Roller Chain Attachment Links — integrate into standard ANSI roller chain to add mounting points for fixtures, slats, or crossrods
Corrosion-Resistant ANSI Roller Chain Attachment Links — steel construction with corrosion-resistant protection for moisture, chemical, or outdoor exposure in food processing, marine, or outdoor applications
Double-Pitch ANSI Roller Chain Attachment Links — sized for double-pitch roller chains, commonly used in conveyor systems and light-duty power transmission

Complete Attachment Chain

These are full chain assemblies with attachment plates already built in, ready to install without sourcing separate links.

ANSI Attachment Chains — complete chain for conveyor systems, material handling, and packaging applications
Double-Pitch Attachment Chain — extended-pitch chain with built-in attachment points for mounting components
High-Strength Corrosion-Resistant Attachment Chain — steel construction with a corrosion-resistant coating for durability in humid or corrosive environments

Adding Links (Extend or Repair an Existing Run)

These are single connecting links sized to match a specific existing attachment chain, used to lengthen a run or replace a damaged section without disassembling the whole chain.

Adding Link for ANSI Number C2050 Double-Pitch Roller Chain — matches C2050 double-pitch chain for conveyors and material handling systems
Adding Link for ANSI Number 40 Single Strand High-Strength Corrosion-Resistant Roller Chain — matches #40 corrosion-resistant chain for marine, food-processing, or chemical-industry equipment

Attachment Types: Tab vs. Pin

Attachment chain in this category comes in two mounting styles. Tab attachments (designated A-1, K-1, SA-1, or SK-1) use flat plates riveted to the link for bolting on slats, buckets, or fixtures. Pin attachments (designated D-1 or D-3) use an extended pin protruding from the link as a mounting stud or pivot point instead of a flat plate. Check the specific product's spec sheet for exact hole spacing and pin length before ordering, since these details vary by trade size.

Where Is ANSI Attachment Chain Used?

Conveyor systems — carrying buckets, slats, or crossrods for bulk material transfer
Material handling — customized transport of parts, packages, or bulk goods
Packaging equipment — mounting fixtures or pushers at fixed intervals along the line
Food processing, marine, and outdoor equipment — using corrosion-resistant attachment chain and links

Frequently Asked Questions

What is the difference between an attachment "link" and an attachment "chain"?

An attachment link is a single component that you install into a standard chain you already own, replacing a plain link at set intervals. Attachment chain is a complete, pre-assembled chain that already has the attachment plates or pins built in, ready to install as a whole unit.

What's the difference between tab and pin attachments?

Tab attachments use a flat plate riveted to the link, with holes for bolting on slats, buckets, or other fixtures. Pin attachments use an extended pin that protrudes from the link itself, used as a mounting stud or pivot point where a flat bolt-on plate isn't practical.

Is ANSI attachment chain available in stainless steel?

No — the attachment chain and links in this category are steel construction, including the corrosion-resistant options, which use a protective coating on steel rather than stainless steel material. If a project requires stainless steel roller chain specifically, check the Metric or standard ANSI roller chain categories, which do include stainless steel options.

What is an "adding link" used for?

An adding link is a single connecting link sized to match a specific existing chain, used to lengthen a chain run or replace a damaged link without disassembling or replacing the entire chain.

What is double-pitch attachment chain used for?

Double-pitch attachment chain spaces the links at twice the standard pitch, reducing weight and part count for a given length. It's used in conveyor systems and light-duty power transmission where slower speeds and lighter loads make the wider spacing practical.

Is attachment chain available in double-strand construction?

No — attachment chain and links in this category are single-strand only. If a conveying application needs the higher load capacity of double-strand chain, standard ANSI roller chain (without attachments) is available in double-strand construction instead.
