What Is Metric Roller Chain?

Metric roller chain is roller chain built to ISO 606 (equivalent to DIN 8187 and British Standard) metric dimensions, identified by B-series trade sizes rather than ANSI numeric sizes. LILY Bearing stocks metric roller chain in trade sizes 04B through 28B, in single and double strand (-2) construction, in steel and stainless steel — stainless steel is available in 05B, 06B, 08B, 10B, 12B, and 16B only.

Repair & Connecting Links for Heavy-Duty B-Series Chain

LILY Bearing stocks individual repair links sized to match Heavy Duty metric roller chain, offered under two naming lines — Adding-and-Connecting Link and Connecting Link — across trade sizes 05B through 28B. Confirm the exact link type against your existing chain's specification sheet before ordering, since a functional distinction between the two naming lines isn't documented on the individual product pages.

Where Is Metric Roller Chain Used?

  • Metric and imported machinery — direct replacement chain on equipment built to ISO 606 / DIN 8187 dimensions
  • General industrial machinery — drives and low- to medium-speed power transmission
  • Conveying and material handling — using hollow-pin chain for easy attachment mounting
  • Marine, chemical processing, and outdoor equipment — using corrosion-resistant or high-strength corrosion-resistant chain
  • Hard-to-access installations — using maintenance-free chain to minimize downtime

 

Frequently Asked Questions

What is the difference between metric (B-series) and ANSI roller chain?

Metric roller chain follows ISO 606 (equivalent to DIN 8187 and British Standard) dimensions and uses B-series trade sizes such as 08B or 10B, while ANSI roller chain (ANSI B29.1) uses inch-based pitches and numeric trade sizes such as #40 or #60. The two are not interchangeable on the same sprocket, even at a similar pitch, because roller diameter, pin diameter, and link plate dimensions differ between the standards.

 

Which metric chain sizes are available in stainless steel?

Stainless steel is available in 05B, 06B, 08B, 10B, 12B, and 16B only. Sizes 04B, 081, 20B, 24B, and 28B are stocked in steel construction only.

 

What is hollow-pin metric roller chain used for?

Hollow-pin chain uses pins with a bore through the center, allowing brackets or other attachments to be bolted directly through the pin without disassembling the chain. It's commonly used in conveyor and material handling systems that need components mounted at fixed intervals.

 

What's the difference between an "Adding-and-Connecting Link" and a "Connecting Link" for heavy-duty B-series chain?

Both are individual repair links sized to match Heavy Duty metric roller chain in the same trade size, used to extend or repair an existing chain run. The specification pages don't document a functional distinction between the two naming lines, so confirm the exact link style needed against your existing chain before ordering.

 

Is double-pitch chain available in this category?

No — every product in this category is standard (single) pitch type. Double-pitch chain is offered separately under the attachment chain category for applications that need the wider link spacing.

 

Should I choose single-strand or double-strand metric roller chain?

Single-strand chain is the standard choice for most drives, while double-strand (-2) chain adds a parallel row of links on a common pin to increase load capacity within the same pitch. Choose double-strand chain when the application's load or horsepower requirement exceeds what the single-strand version of that trade size can carry.
