Sprocket Detailed Product Introduction

1. Product Overview

2. Raw Material Options & Advantages

1. C45/45# Carbon Steel (Most Popular)

   High tensile strength, low cost, easy heat treatment. Tooth surface induction quenched to 45–55 HRC, outstanding wear resistance for general heavy-duty machinery, conveyors and agricultural machines.

2. 304/316 Stainless Steel

   Full rust & corrosion resistance, food-grade and acid-proof. Ideal for food processing, chemical plants, marine and humid workshop environments.

3. Alloy Steel (40Cr)

   Higher hardness and impact resistance, suitable for high-torque, high-speed and heavy-load working conditions like mining and construction machinery.

4. Cast Iron HT200/HT250

   Good shock absorption, low noise, low price, applied to low-speed light-load conveying equipment.

5. Nylon PA66+Glass Fiber Plastic Sprocket

   Light weight, self-lubricating, ultra-low noise, used for small office equipment and light automated lines.

3. Production & Processing Technology

1. CNC precision turning for inner bore, hub and keyway to guarantee concentricity, no shaking during operation.

2. Professional gear hobbing machine for tooth processing, smooth tooth profile, tight fit with chains to reduce abrasion and tooth skipping.

3. Heat treatment: Induction hardening only on tooth surface, retain hub toughness to avoid fracture under impact load.

4. Surface treatment options: Black oxide, zinc plating, sandblasting, polishing to prevent rust and extend service life.

5. Finished bore with standard keyway, set screw holes for direct installation; rough bore and taper lock bush types are customizable.

4. Main Product Classification
