Sprockets and Gear

compatible with all standard ANSI and BS/DIN roller chains. Manufactured from premium carbon steel (C45), alloy steel, and stainless steel with induction-hardened teeth, our sprockets ensure maximum wear resistance, smooth meshing, and extended service life. We supply finished bore sprockets, taper-lock sprockets, idler sprockets, and fully customized gears tailored to your high-load industrial machinery.

Material Selection & Tooth HardeningOperating environments dictate material grade and heat-treatment specifications:
Carbon Steel (C45 / 1045): Standard robust material providing excellent structural strength and machining performance.
Induction-Hardened Teeth: Optional high-frequency hardening on sprocket teeth (HRC 38-52) to dramatically reduce tooth wear under high-torque, abrasive industrial operations.
Stainless Steel (SUS304 / SUS316): Corrosion-resistant sprockets built for food processing, washdown, and chemical plant applications.

Sprockets and gears are critical toothed machine elements designed to transmit rotary motion and torque between shafts without slippage. While gears mesh directly with one another, sprockets feature specialized tooth profiles designed to engage seamlessly with industrial roller chains, providing reliable, synchronous power transmission across heavy-duty mechanical drives.
Standard Sprocket Configurations AvailableYONGHANG manufactures a vast inventory of standard and custom sprockets to meet global engineering requirements:
ANSI Sprockets (American Standard): Engineered to match ANSI B29.1 roller chains (from ANSI 25 up to ANSI 160). Available in Simplex (single strand), Duplex (double strand), and Triplex (triple strand) execution.
BS / DIN Sprockets (European Standard): Designed in accordance with ISO 606 standards (from 04B up to 32B), widely used in European automated packaging and material handling machinery.
Type A, B, C & D Sprockets: Offering plate wheels (Type A - no hubs), single-hub sprockets (Type B), double-hub sprockets (Type C), and split sprockets for easy installation without dismantling drive shafts.
Taper-Lock & Finished Bore Sprockets: Sprockets pre-bored with standard keyways and set screws, or designed to accept taper bushings (QD / Taper-Lock bushings) for quick and secure shaft mounting.
