Regal Rexnord
Roller Chain
Regal Rexnord roller chain is the globally standardized, roller - equipped power - transmission chain that drives mechanical systems in virtually every sector of industry — agricultural equipment, material - handling conveyors, packaging machinery, construction equipment, and general industrial drives.Under the Rexnord and Link - Belt brands, our roller chain line includes ANSI standard sizes(25 through 240), metric ISO chain(06B through 48B), heavy - series and super- heavy - series chain for high - load applications, and attachment chain with extended pins and special link plates for conveyor assembly.Plant maintenance teams, OEM engineers, and agricultural equipment dealers select Regal Rexnord roller chain for its consistent dimensional accuracy, precisely heat - treated pins and bushings that deliver predictable wear life, and the fatigue - resistant link plates that survive the pulsating loads and shock loads of industrial drives.Available in standard carbon steel, nickel - plated, stainless steel, and with solid bushings or split bushings as the application demands, our roller chain provides the balance of strength, wear life, and cost that has made it the predominant mechanical drive chain for over a century.

Trusted by Industry Leaders
ANSI & ISO Standard Interchangeability
Manufactured to ANSI B29.1 and ISO 606 dimensional standards, ensuring compatibility with sprockets and connecting links from all major manufacturers.
Precision Heat - Treated Pins & Bushings
Through - hardened and case -hardened components provide the core toughness and surface hardness that resist both shock - load fracture and abrasive wear in industrial environments.
Heavy & Super - Duty Series for High Loads
Thicker link plates and larger pin diameters in heavy - series chain increase fatigue strength and shock - load capacity — essential for construction equipment, mining conveyors, and agricultural combines.
Solid & Split Bushing Options
Solid bushings for maximum load capacity; split bushings where lubricant flow - through is required or where the chain must be assembled around a captive shaft.
Corrosion - Resistant Platings & Materials
Nickel - plated and stainless - steel roller chain for washdown, food - processing, chemical, and outdoor installations where carbon - steel chain life is limited by rust.
Attachment Link Configurations for Conveying
K1, K2, A - type, and custom attachment links that bolt directly to the chain, enabling the chain to serve as both the drive element and the conveying surface.
Roller Chain for Agricultural Equipment & Heavy Machinery
Agriculture and construction equipment operate roller chain in the most difficult conditions possible — exposure to dirt, sand, crop materials, and weather, combined with the high shock loads of engaging a rock in a combine feeder house or the start - up torque of a loaded construction elevator.Regal Rexnord heavy - series roller chain, with its thicker sidebars and larger pins, is engineered for these environments.The Rexnord and Link - Belt brands have been specified on John Deere, Case IH, Caterpillar, and other major equipment OEMs for decades, providing the reliability that minimizes in -field downtime during the narrow harvest and construction - season windows.Our distribution network across North America ensures that replacement chain is available locally during the peak - demand periods when equipment uptime directly determines revenue.
Roller Chain Lubrication & Installation Best Practices
Correct lubrication is the single greatest determinant of roller chain service life.The pin - bushing articulation requires an oil film to prevent metal - to - metal contact; the most common cause of premature roller - chain failure is inadequate or incorrect lubrication.Manual drip, oil - bath, and automatic spray - lubrication systems are available for different chain speeds and accessibility.Regal Rexnord provides lubrication recommendations, chain - length calculators, and sprocket - alignment guidelines that enable plant maintenance teams to install and maintain roller chain drives for maximum service life.For difficult - to - access lubrication points, our self - lubricating sintered - bushing chain eliminates the need for periodic relubrication — particularly valuable in conveying applications where chain lubrication could contaminate the product or the environment.
