6Y3222RCU

The 6Y3222RCU is a Caterpillar-compatible standard bucket tooth from the J225 series — a light-duty CAT tooth system for small excavators and backhoe loaders working in utility and residential construction. Manufactured as a premium aftermarket replacement by AzuLong Wear Parts, it is designed for small-to-mid excavators and backhoe loaders.

Standard Profile — Application & Performance

The standard profile provides optimal balance between penetration and wear resistance. It is the most versatile tooth design for everyday excavation work, handling mixed soil conditions including topsoil, clay, and loose gravel. The profile geometry is optimized for self-sharpening wear — as the tooth wears down, it maintains a relatively sharp digging edge rather than going blunt.

Material & Durability

At 2.66 kg, this tooth is built for 10-14 ton class equipment. This compact tooth is manufactured from heat-treated alloy steel with a target hardness of HRC 48-52. The lighter weight makes field changes fast and reduces bucket drag, improving fuel efficiency during extended digging cycles. The alloy steel composition provides balanced resistance to both abrasive wear from sandy soils and impact damage from occasional rock contact.
