Scarifier Teeth: Shank Diameter 25-40 mm, Length 150-300 mm

Component Specifications

Definition

Scarifier teeth are hardened steel components mounted on rotating drums or fixed frames of scarifying machinery. They penetrate and fracture compacted materials through mechanical force, creating grooves or removing surface layers. These teeth are engineered for high impact resistance and wear tolerance in abrasive environments.

Working Principle

Scarifier teeth operate on the principle of concentrated mechanical force application. As the scarifier machine moves forward, the teeth penetrate the surface material. Their tapered geometry creates wedging action that fractures compacted layers, while their arrangement ensures consistent depth and pattern across the working width.

Materials

Medium-carbon alloy steel (typically 4140 or 4340 grade, about 0.40% C), heat-treated to 45-55 HRC hardness. Some premium versions use tungsten carbide inserts or overlay welding on cutting edges for enhanced wear resistance.

Frequently Asked Questions

How often should scarifier teeth be replaced?

Replacement frequency depends on material hardness and operating hours. Typically every 50-100 hours in abrasive conditions. Regular inspection for wear and damage is recommended.

Are scarifier teeth interchangeable between different machine brands?

Compatibility varies by mounting system and dimensions. While some universal patterns exist, most teeth are brand-specific. Always verify mounting specifications before purchasing replacements.
