195-78-21331

The 195-78-21331 is an aftermarket replacement bulldozer tooth compatible with Komatsu D355/D375 excavators — an aftermarket ripper point for Komatsu D355/D375 mining-class bulldozers. Manufactured by AzuLong Wear Parts to match OEM specifications, it provides reliable digging performance for Komatsu mining-class bulldozers performing deep ripping.

Bulldozer Profile — Application & Performance

Purpose-built for bulldozer blade applications including pushing, grading, slot dozing, and land clearing. The reinforced shank design withstands the lateral forces common in dozer operations, where teeth encounter loads from multiple angles as the blade pushes material forward and to the sides.

Material & Durability

At 15.5 kg, this tooth is built for mining bulldozer class equipment. This heavy-duty tooth is forged from heat-treated alloy steel and finished to HRC 48-58, with the higher hardness range available for demanding rock and mining applications. The increased cross-section provides greater resistance to the bending loads that occur during heavy ripping and prying operations. The heat treatment process is tightly controlled to prevent internal stresses that could cause premature failure under shock loading.
