Anti-Rust Surface Blackening Treatment Sprocket

Product Introduction

Main Specifications

• Base material: Medium carbon steel / alloy steel

• Surface craft: High-temperature blackening oxidation process

• Hardness: Teeth quenched for wear resistance

• Matching standard: ANSI, DIN, JIS roller chains

• Customizable: Tooth count, bore, keyway, simplex/duplex types

Core Advantages

1. Reliable Anti-Rust Barrier

   Uniform black oxide film tightly covers the whole sprocket surface, isolating air and moisture to avoid oxidation rust without thick coating affecting assembly precision.

2. No Interference With Meshing

   Thin and compact blackening layer won’t change tooth pitch size, ensuring tight, stable chain engagement without jumping or extra friction loss.

3. High Wear Resistance

   Combined tooth hardening and blackening double protection, slowing abrasion during long continuous conveying and drive operation.

4. Matte Anti-Glare Surface

   Dark matte finish avoids light reflection on production lines, also resisting fingerprint and minor oil stains for easy cleaning.

5. Cost-Effective Anti-Corrosion Solution

   Cheaper than galvanizing or stainless steel while meeting daily anti-rust demands of general industrial transmission machinery.
