Regal Rexnord
Sprockets & Wheels
Regal Rexnord industrial chain sprockets and wheels are precision - machined drive components that engage and transmit power to roller chain, silent chain, engineered steel chain, and drop forged chain across every industrial, agricultural, and material - handling application.Unlike the molded or stamped sprockets found in light - duty applications, our industrial sprockets — manufactured under the Browning, Rexnord, and Link - Belt brands — are machined from steel plate, forgings, or castings to the tooth - profile accuracy that ensures smooth chain engagement, minimal vibration, and even load distribution across the sprocket teeth.Plant engineers specify Regal Rexnord sprockets for the dimensional accuracy that maintains chain life, the material hardness that resists tooth wear in abrasive and high - cycle applications, and the extensive bore, keyway, and bushing options that provide drop -in interchangeability with existing equipment.With stock sprockets available for ANSI, ISO, and specialty chain series, flame - hardened tooth surfaces that extend service life on high - horsepower drives, and engineered split - sprocket designs that enable replacement without shaft disassembly, our sprocket line supports the reliable operation of chain drives from fractional - horsepower conveyors to multi - thousand - horsepower bulk - material elevators.

Trusted by Industry Leaders
AGMA & ISO Standard Tooth - Profile Accuracy
Tooth profiles machined to the geometric tolerances that ensure proper chain - roller seating and smooth hand - off between teeth — the foundation of long chain and sprocket life.
Flame - Hardened Tooth Surfaces for Wear Resistance
Induction or flame - hardened tooth contact surfaces resist the abrasive and high - cycle wear that causes tooth - profile degradation and chain elongation on high - horsepower drives.
Split - Sprocket Designs for Easy Replacement
Two - piece split sprockets that can be removed and replaced without removing the shaft, bearings, or adjacent machinery — cutting sprocket - replacement time by 50 % or more.
QD, Taper - Lock & Fixed - Bore Mounting
Complete compatibility with all major bushing systems, plus fixed - bore and keyseated configurations for direct shaft mounting — one sprocket source for every drive specification.
Custom Tooth Counts & Pitch Diameters
Beyond stock sizes, our manufacturing capabilities produce sprockets with any tooth count and bore configuration required for special - ratio and retrofit applications.
Material & Hardness Options for Every Environment
Carbon steel for general use, through - hardened alloy steel for high - load / high - cycle drives, stainless steel for food and chemical environments, and engineered polymers for clean, low - noise applications.
How Sprocket Wear Accelerates Chain Elongation
Worn sprockets are a primary cause of reduced chain life, often overlooked because attention focuses on the chain itself.As sprocket teeth wear — developing a hooked or “shark - fin” profile — the chain rollers no longer seat correctly in the tooth root, concentrating load on fewer teeth and creating uneven link - plate loading that accelerates pin and bushing wear.A chain replaced on worn sprockets will elongate at two to three times the normal rate, effectively wasting the new chain investment.Best practice is to replace sprockets at every second or third chain change, or whenever tooth wear exceeds 5 % to 10 % of the original profile.Regal Rexnord provides sprocket - wear gauges and inspection training to help maintenance teams make objective replacement decisions that maximize chain - and - sprocket system life.
Selecting Sprockets for Roller, Engineered & Silent Chain
Each chain type requires sprockets with specific tooth geometry, hardness, and hub configuration.Roller chain sprockets follow ANSI / ISO tooth profiles; engineered steel chain sprockets require custom tooth shapes matched to the specific chain series(WH, WHD) and are typically supplied as part of the original conveyor system.Silent chain sprockets are essentially involute gears, requiring high tooth - profile accuracy for the progressive engagement that defines silent chain performance.Regal Rexnord’s sprocket engineering team ensures that the sprocket specified for each chain type correctly matches the chain’s pitch, roller or tooth geometry, and operating speed, providing a sprocket - and - chain system optimized for reliability.
