Center Roller Conveyor Chain

What Is a Center Roller Conveyor Chain?

Our Center Roller Conveyor Chain is a specialized conveying chain featuring an additional free‑rotating roller positioned between the inner and outer link plates. This center roller is typically larger in diameter than the chain’s own bushings and provides a low‑friction product support surface while the chain engages with standard drive sprockets. Manufactured in accordance with ISO 606 and ANSI B29.1 standards, this design enables smooth accumulation, zero‑pressure conveying, and reduced product marking without the need for separate top roller attachments.

Key Features of Center Roller Conveyor Chain

• Free‑rotating center roller mounted between inner and outer plates for stable product support

• Roller materials available in hardened steel, acetal (POM), or nylon for application‑specific friction and wear performance

• Heat‑treated pins and bushings for extended chain life

• Standard chain rollers engage with sprockets while center rollers contact the product – independent rotation

• Pre‑stressed assembly to minimize initial elongation and maintain pitch accuracy

• Compact design – no increase in chain width compared to standard roller chain

Technical Specifications of Center Roller Conveyor Chain

• Standards: ISO 606, ANSI B29.1

• Chain pitches: Short pitch metric (08B, 10B, 12B, 16B) or inch (40, 50, 60)

• Center roller material options: Hardened steel (high load, wear resistance), acetal (low friction, quiet), nylon (non‑marking, FDA‑compliant available), anti‑static grades for electronics

• Center roller diameter: Larger than standard roller – varies by chain size (refer to data sheet per model)

• Center roller width: Determined by chain link plate spacing – standard or customized

• Roller spacing: Every link (standard) or custom intervals

• Tensile strength: Conforms to base chain specifications – refer to data sheet per model

• Operating temperature: Steel center rollers: -20°C to +200°C; plastic center rollers: -10°C to +80°C typical

Applications of Center Roller Conveyor Chain

• Assembly line accumulation zones requiring zero‑pressure product stop

• Packaging conveyors and bottling/canning lines

• Automated warehousing and pallet handling systems

• Electronics assembly and cleanroom environments (non‑lubricated plastic roller options)

• Any conveying operation where products must accumulate without backline pressure or scuffing

Customization Options for Center Roller Conveyor Chain

• Center roller materials: Hardened steel, acetal, nylon, anti‑static, FDA‑compliant plastic

• Roller spacing: Every pitch, every second pitch, or custom intervals to match product pitch

• Base chain: Carbon steel, stainless steel (304 or 316), or nickel‑plated finishes

• Attachments: Extended pins, A/K attachments, or side guides available

• Lubrication: Standard, food‑grade, or lubrication‑free (with plastic center rollers)

• Surface finishes: Black oxide, zinc plating, or passivation for stainless steel

Quality & Compliance of Center Roller Conveyor Chain

• Manufactured under ISO 9001 quality management

• Full material traceability and dimensional verification

• Stainless steel mill certificates and FDA certificates for plastic rollers available upon request

• Consistent quality ensuring reliable interchangeability with major global brands
