Regal Rexnord
Conveyor Sprockets and Wheels
Regal Rexnord conveyor sprockets and wheels are precision - machined, application - engineered drive components that engage and power modular plastic belts, TableTop chains, and engineered steel chains across the full range of conveying applications.Under the Rexnord, Link - Belt, and Browning brands, our sprocket portfolio spans split and solid - hub drive sprockets, idler sprockets, return wheels, and custom - engineered sprocket configurations in materials ranging from hardened carbon steel and stainless steel to engineered polymers and cast iron.Maintenance engineers and conveyor system designers specify Regal Rexnord sprockets to achieve positive, slip - free belt or chain engagement that maintains precise product timing, minimizes pulsation - induced vibration, and distributes wear evenly across belt or chain contact surfaces.With manufacturing capabilities supporting sprocket diameters from under 2 inches to over 48 inches, bore configurations covering every bushing system — QD, Taper - Lock, split - taper — and tooth profiles optimized for each specific chain or belt series, our conveyor sprockets deliver the geometric precision and material durability that maximize the service life of both the sprocket and the conveying medium it drives.

Application - Specific Tooth Profile Engineering
Sprocket tooth geometry optimized for the exact pitch, roller diameter, and flight configuration of each Rexnord chain or belt series, ensuring smooth, quiet engagement and even wear distribution.
Hardened Wear Surfaces for Extended Life
Induction - hardened or case -hardened tooth surfaces resist abrasive wear on high - speed and high - load conveyor drives, extending replacement intervals by 3x to 5x over unhardened sprockets.
Split - Hub Design for In - Situ Replacement
Two - piece sprockets that can be removed and replaced without dismounting the shaft or disturbing adjacent components, slashing maintenance downtime on long - line conveyors.
Multi - Material Selection
Hardened steel for heavy - load aggregate conveyors, stainless steel for washdown food environments, engineered polymers for low - noise, lubrication - free operation in cleanroom and packaging applications.
Universal Bushing Compatibility
Bore configurations accept QD, Taper - Lock, and split - taper bushings from all major manufacturers, simplifying interchange and enabling bore - size changes without replacing the sprocket body.
Idler & Return Wheel Packages
Complete idler sprocket and return wheel assemblies with integrated bearing mounts, pre - greased and sealed, ready for bolt -in installation on conveyor return ways and tensioning stations.
Why Sprocket Quality Directly Impacts Conveyor Performance
The sprocket is often overlooked as a commodity component, yet sprocket quality — particularly tooth - profile accuracy and surface hardness — directly determines chain and belt service life, system vibration levels, and product - handling precision.Sprockets with inaccurate pitch or tooth - profile errors cause chordal action: a cyclic speed variation that produces vibration, accelerates chain - joint wear, and degrades product - transfer timing between conveyors.Worn sprocket teeth create a "pocketing" effect where chain rollers no longer seat correctly, concentrating load on fewer teeth and dramatically accelerating chain elongation.Regal Rexnord conveyor sprockets are manufactured using CNC hobbing and grinding processes that hold tooth-profile tolerances to AGMA Class 8 or better, ensuring that every tooth carries its designed share of the load.Our proprietary induction - hardening patterns produce wear - resistant case depths without through - hardening that could cause brittle fracture under shock loading.The result is a sprocket that maintains its original tooth profile for the full service life of the chain or belt it drives.
Sprocket Selection, Inspection & Replacement Best Practices
Effective sprocket management extends conveyor - system life and minimizes unplanned downtime.As a best practice, maintenance teams should replace sprockets every second or third chain replacement — or whenever tooth wear exceeds 10 % of the original profile dimension.Visual inspection indicators include hooked or shark - finned tooth shapes, polished wear steps at the chain - roller contact line, and measurable pitch increase that causes chain rollers to ride higher on the tooth flank.When replacing sprockets in multi - strand chain drives, all sprockets on a common shaft should be replaced simultaneously to ensure even load sharing between strands.Regal Rexnord offers sprocket condition - assessment training, on - site inspection services, and pre - kitted replacement packages that include sprockets, bushings, keys, and fasteners for scheduled conveyor maintenance outages.Our Edge selection tool allows maintenance planners to identify the correct sprocket part number from chain or belt series, tooth count, and bushing type, generating CAD models and interchange data within minutes.
