Regal Rexnord
Chain Components
Regal Rexnord chain components are the individual precision - manufactured elements — links, pins, bushings, rollers, and attachment plates — that assembly into the welded - steel, engineered - steel, and forged chain lengths that power the world’s most demanding bulk - material elevators, conveyors, and heavy - duty mechanical drives.Designed for the abrasion, shock loads, and corrosive environments of cement, aggregate, lumber, and grain - handling industries under the Rexnord and Link - Belt brands, these components provide plant maintenance teams and chain - assembly houses with the genuine replacement parts that extend chain service life and maintain the dimensional precision that prevents sprocket mismatch and premature joint failure.Ordering individual chain components instead of complete chain lengths allows targeted replacement of the highest - wear elements — pins and bushings at the chain joints — reducing material cost while restoring chain pitch to specification.With heat - treated alloy steels, induction - hardened wear surfaces, and stainless - steel and zinc - plated options for corrosive service, Regal Rexnord chain components deliver the metallurgical integrity and geometric tolerances required for drop -in interchangeability with original chain assemblies.

Trusted by Industry Leaders
Induction - Hardened Pin & Bushing Surfaces
Pin outside diameters and bushing inside diameters selectively hardened for maximum wear resistance while retaining core ductility for shock - load survival.
Precision Interchangeability
Components manufactured to the original chain series dimensional tolerances, ensuring proper fit and joint articulation without the tight spots that accelerate wear.
Material Traceability & Certified Chemistry
Alloy steel components with documented heat numbers and mechanical properties, providing the quality assurance required by critical - elevator and conveyor applications.
Welded - Steel Chain Component Stocking
Standard components for the most common welded - steel chain series(WH, WHD, C - type) stocked for immediate shipment, minimizing outage duration on critical conveying lines.
Attachment Link Configurations
K1, K2, A - type, and custom attachment plates available as separate components for field modification of chain configurations without replacing full chain lengths.
Stainless & Plated Corrosion Protection
304 / 316 stainless - steel components for food - processing and chemical environments; zinc - plated and other coating options for mildly corrosive outdoor duty.
Pin & Bushing Replacement: Extending Welded - Steel Chain Life
In welded - steel and engineered - steel chain applications, the chain joints wear at the pin / bushing interface long before the sidebars lose structural strength.Replacing the pins and bushings while retaining the original sidebars and attachments can restore the chain’s pitch to within new- chain tolerances at a fraction of new chain cost.This partial - rebuild approach is standard practice in cement, lime, and aggregate plants, where chain lengths on bucket elevators and drag conveyors can be hundreds of feet long and represent a significant capital investment.Regal Rexnord’s stocking of standard component sizes enables maintenance teams to perform these partial rebuilds on planned shutdown schedules, maintaining chain reliability while optimizing total lifecycle cost.Our application guidelines provide the wear - measurement methods and replacement criteria that define when partial rebuild is appropriate versus when full chain replacement is the more economical long - term decision.
Chain Component Quality & The Cost of Non - OEM Parts
Premature chain failure is often traceable to non - OEM replacement components with incorrect material hardness, surface finish, or dimensional tolerances.Pins that are too soft wear rapidly, causing chain elongation that sprockets cannot tolerate.Pins that are too hard or not properly case -controlled can fracture under the bending loads at the joint.Regal Rexnord chain components are manufactured in our ISO - certified facilities with the specific material specifications, heat - treat cycles, and dimensional controls that the chain was designed for.For operations experiencing chronic chain - life issues, our metallurgical lab offers failed - component analysis that identifies the failure mode — abrasive wear, corrosion pitting, or fatigue — enabling the corrective actions that restore expected chain life.
