ZHZBearing New Arrival: OEM Replacement Bearings for Komatsu D155A Series Bulldozers OEM replacement bearings exclusively for Komatsu bulldozers, tailored for heavy-duty and harsh working conditions Bulldozers consistently operate under severe construction conditions featuring heavy load impacts, sand and dust. Bearings in the travel system are highly prone to wear and damage, making them core replacement parts for equipment maintenance. ZHZBearing has newly launched two models of bearings for Komatsu bulldozers. Developed specifically for the travel system of Komatsu D155A series bulldozers, these bearings are made of premium GCr15 bearing steel with P0/P6/P5 precision grades available. Manufactured in strict compliance with original equipment standards, they serve as direct OEM replacements and adapt to harsh engineering machinery operating environments, effectively solving common issues such as inflexible traveling, rapid bearing wear and short service life. 1. Komatsu D155A Bulldozer Bearing 17A-15-29321 Model 17A-15-29321 fits Komatsu D155A bulldozers, installed in the equipment’s travel and working device system as a core replacement component for bulldozer travel transmission.Forged from high-quality GCr15 bearing steel, this product delivers high hardness, excellent wear resistance, compression resistance and fatigue resistance. It can withstand construction site dust, sand erosion and frequent heavy-load impacts. With customizable precision grades and precise original dimensions, it enables easy direct replacement, stabilizes equipment traveling performance and greatly reduces equipment failure rates and maintenance costs. 2. Komatsu D155A-6R Bulldozer Bearing 17A-13-39320 Model 17A-13-39320 is specially designed for Komatsu D155A-6R bulldozers and installed in the travel system. It belongs to the same heavy-duty specialized Komatsu bearing series as 17A-15-29321.Adopting premium GCr15 bearing steel, it adapts to long-term high-intensity and high-load operation of bulldozers with outstanding anti-impact, wear-resistant and anti-aging properties. Fully benchmarking original manufacturing specifications and available in multiple precision options, it is ideal for daily maintenance, fault repair and equipment refurbishment, boasting strong compatibility and operational stability.
