At YF Gear, we specialize in precision sprocket wheels for chain drive systems.
Our catalog covers Drive Sprocket Wheels and Roller Sprocket Wheels, engineered for durability, accurate meshing, and long service life.
Used broadly in conveyors, motorcycles, industrial machinery, and material handling systems, our sprockets support various chain types and environmental demands.
We combine CNC machining, heat treatment, and strict quality control to ensure every sprocket meets performance requirements for strength, wear resistance, and alignment precision.
| Parameter | Typical Range / Option | Engineering Detail |
|---|---|---|
| Pitch / Chain Type | ANSI 35 – 80, ISO / DIN standard | Compatible with most roller chains |
| Tooth Count | 10 – 60+ teeth (custom) | Supports different reduction ratios |
| Material | Carbon Steel, Alloy Steel, Stainless Steel | Tailored for load & environment |
| Hardness / Treatment | Carburized, Induction Hardened (HRC 45–55) | Superior tooth wear life |
| Bore Type | Keyed, Splined, Taper, Bossed | Ease of mounting on various shafts |
| Precision Grade | DIN 6, ISO 7 | Low backlash and precise runout |
| Coating / Finish | Black oxide, Zinc, Nickel, PSC plating | Anti-rust, aesthetic, longevity |
| Application Temp. | −20 °C to +200 °C | Works in extreme environments |
| Feature | Drive Sprocket Wheel | Roller Sprocket Wheel |
|---|---|---|
| Function | Transmits drive torque from motor / shaft | Guides or supports chain (idler / return) |
| Load Stress | High – directly drives load | Lower – no drive torque |
| Wear Concern | High wear – needs hardened teeth | Moderate wear – secondary function |
| Design Focus | Torque capacity, tooth strength | Smooth chain run, low friction |
| Use Case | Motor output, drive shaft | Tensioner, return idler in chain loop |
Choose Drive Sprocket when needing primary power transmission.
Use Roller Sprocket in return or support locations to guide chain or reduce sag.
CNC Tooth Profiling for correct chain engagement and reduced fatigue
Heat Treatment ensures durability under repeated cycles
Balancing & Precision Runout Control ≤ 0.05 mm
Surface Enhancement for corrosion, abrasion resistance
Full Material Traceability & QA Testing — fatigue, hardness, dimensional
Conveyor Systems & Material Handling — drive & idler sprockets
Motorcycles / Bicycles — drive sprocket custom parts
Industrial Machinery / Automation — drive chains in presses, cam drives
Agriculture & Heavy Equipment — sprockets exposed to dust, mud
Mining & Construction Equipment — large diameter, robust drive sprockets
Example: In a packaging line, the drive sprocket transmits motor torque to the chain driving frames, while the roller sprocket in the return loop guides the chain and reduces sag, improving life and stability.
| Concern | Customer Question | YF Gear Solution |
|---|---|---|
| Chain Wear | “How long will sprocket last under heavy duty?” | Hardened teeth & wear-resistant coatings extend life >2× baseline. |
| Noise & Vibration | “Will the chain run smoothly in high speed?” | Tooth profiling and tight tolerances reduce chatter. |
| Backlash / Tolerance | “Can I get precise engagement without slop?” | Precision grade DIN6 / ISO tolerance control. |
| Corrosion / Harsh Environments | “Can sprocket resist rust / chemicals?” | Stainless or coated options for corrosive use. |
| Compatibility | “Will it fit my chain / shaft?” | Support for standard chain pitches + custom bore configurations. |
Q1: What is a sprocket wheel used for?
It connects to a chain to transmit motion or guide the chain in drive systems.
Q2: How to choose drive vs roller sprocket?
Drive sprocket transfers torque; roller sprocket acts as guide or idler in a chain loop.
Q3: What chain pitches do you support?
Standard ANSI sizes (35, 40, 50, 60, 80) and ISO / DIN metric chains.
Q4: Can sprockets be customized by tooth count or bore?
Yes – we support full customization including tooth number, bore design, keyways, etc.
Q5: What hardness is appropriate for high load?
Teeth typically hardened to HRC 45–55 for durability under heavy load cycles.
Q6: Are these sprockets RoHS / ISO certified?
Yes — we provide certifications and material reports on request.
ISO 9001:2015 quality management system
Material certificates and heat treatment reports
Precision inspection (tooth profile, runout, hardness)
Coating & corrosion resistance testing
