Top-selling excavator undercarriage rollers and bolts β proven performance in Brazil's demanding jobsite conditions.




Brazil is one of Latin America's largest heavy equipment markets. Understanding local conditions helps us deliver the right solutions.
Brazil's iron ore, bauxite, and gold mining sectors β especially in Minas Gerais and ParΓ‘ β deploy thousands of excavators and bulldozers daily. Harsh, abrasive terrain demands high-wear-resistance bottom rollers with reinforced seals and case-hardened steel construction to withstand continuous operation.
Brazil's ongoing urbanization and government infrastructure programs β including road expansion, port development, and hydropower projects in the Amazon basin β drive massive demand for excavator undercarriage parts. Track rollers and bottom rollers are among the highest-turnover replacement components on Brazilian job sites.
As the world's leading soybean and sugarcane producer, Brazil's agricultural sector relies heavily on tracked machinery for land clearing, drainage, and field preparation across the Cerrado and Mato Grosso regions. Reliable bottom rollers ensure uninterrupted operations across soft and waterlogged terrain.
Petrobras and offshore support industries require precision-built undercarriage components for pipeline laying, platform construction, and coastal engineering works. Corrosion-resistant, salt-spray-tested bottom rollers are essential for coastal and offshore construction environments in Brazil.
Brazil's forestry operations and reforestation initiatives β spanning millions of hectares β require robust excavator components capable of operating in remote jungle conditions with limited access to service centers. Long-lasting bottom rollers reduce downtime and transportation costs significantly.
Major port expansions at Santos, ParanaguΓ‘, and ItajaΓ involve heavy excavation, dredging, and civil engineering works. Precision undercarriage parts β including high-precision track rollers β support the excavators and cranes working in these critical coastal logistics hubs.
Our factory's main products include: track roller (bottom roller), carrier roller (top roller), sprocket, idler, track link assembly, track shoe, bushing & pin, Bucket teeth, high-strength bolts and nuts.

View MoreEngineered to withstand Brazil's toughest operational environments β from Amazon rainforests to Cerrado savannahs and coastal mining regions.
Precision-forged from medium-carbon alloy steel with induction hardening β delivering HRC 52β60 surface hardness for extended service life in abrasive Brazilian soils.
Advanced floating metal face seals prevent oil leakage and moisture ingress β critical for Brazil's tropical humidity, river crossings, and waterlogged agricultural terrain.
Manufactured to OEM specifications for Komatsu, Caterpillar, Hitachi, Volvo, Kobelco, and Doosan β the most widely used excavator brands across Brazil's construction and mining sectors.
Heat-treated steel with anti-corrosion surface treatment withstands Brazil's extreme temperature swings, coastal salt spray, and humid tropical conditions without premature wear.
Brazil's construction and heavy equipment landscape is evolving rapidly β here's what's shaping the market for undercarriage components.
Brazil's PAC (Programa de AceleraΓ§Γ£o do Crescimento) infrastructure program is injecting hundreds of billions into roads, railways, ports, and energy projects. This surge in civil engineering activity is directly fueling demand for excavator undercarriage replacement parts across the country.
Brazil is among the world's top producers of iron ore, niobium, manganese, and bauxite. As Vale, Anglo American, and other mining giants expand operations, fleets of large excavators and bulldozers require regular bottom roller replacements β making reliable suppliers essential.
Brazilian equipment operators are increasingly selecting high-quality aftermarket undercarriage parts over OEM pricing, seeking cost savings without sacrificing reliability. Hesen's OEM-equivalent quality at competitive pricing aligns perfectly with this market trend.
Brands such as XCMG, SANY, Liugong, and Zoomlion have gained significant market share in Brazil. As Chinese excavators become more prevalent, demand for compatible undercarriage parts β including bottom rollers manufactured in China β is growing rapidly among Brazilian dealers and operators.
Brazilian importers are increasingly sourcing undercarriage parts directly from Chinese manufacturers via digital platforms, bypassing intermediaries. This direct-sourcing trend reduces costs and improves supply chain flexibility for Brazilian equipment distributors and rental companies.
Driven by ESG commitments and cost pressures, Brazilian construction companies are extending equipment lifecycles through preventive maintenance. High-quality bottom rollers with extended wear life are central to this strategy, reducing total cost of ownership on long-duration projects.

Our bottom rollers and undercarriage parts are deployed across Brazil's most demanding operational environments β from northern Para state to southern Rio Grande do Sul.
The world's largest iron ore deposit relies on massive Caterpillar and Komatsu excavators. Our hardened-steel bottom rollers deliver 3,000β5,000+ operating hours in this highly abrasive environment.
Major highway expansion projects across the Amazon and Center-West regions require excavators working in dense forest, clay soils, and river crossings β conditions where sealed bottom rollers are essential for reliability.
Agricultural machinery in Mato Grosso works in soft, sandy soils during wet season and compacted hardpan during dry season. Our bottom rollers with dual-lip seals handle both extreme conditions without oil leakage or premature wear.
Rapid urban expansion in Brazil's major cities drives continuous excavation and foundation work. Compact and mid-size excavators in urban environments need precision-fit bottom rollers for maneuvering in tight spaces without damaging streets and structures.
Brazil's hydroelectric sector involves massive civil works in river valleys. Excavators operating in riverbed conditions β with constant water exposure β depend on our waterproof-sealed bottom rollers to maintain operational continuity.
Port expansion and coastal infrastructure projects expose undercarriage components to salt spray and high humidity. Our anti-corrosion-treated bottom rollers maintain dimensional integrity and oil seal performance in marine environments.
A bottom roller β also known as a track roller or lower roller β is a critical component of an excavator's undercarriage system. Positioned along the bottom of the track frame, bottom rollers support the machine's weight and guide the track chain, ensuring smooth travel across uneven terrain. Each excavator typically uses between 5 and 9 bottom rollers per side, depending on the machine's size and model.
In Brazil's diverse operational environments β ranging from the rocky terrain of Minas Gerais mining sites to the soft, waterlogged soils of Amazonian construction zones β bottom rollers face extreme stress from continuous load-bearing, abrasive soil particles, and temperature fluctuations. Selecting a high-quality bottom roller supplier is therefore critical for controlling maintenance costs and maximizing machine uptime.
Quanzhou Hesen Machinery Industry Co., Ltd has been manufacturing excavator bottom rollers and complete undercarriage parts for over 30 years. With compatibility coverage for the world's leading excavator brands β Komatsu, Caterpillar, Hitachi, Doosan, Hyundai, Volvo, and more β our product range meets the full spectrum of requirements from Brazilian dealers, rental companies, and end-users.
Our bottom rollers are produced using medium-carbon alloy steel, precision-machined on CNC equipment, and undergo induction hardening and tempering to achieve optimal hardness and toughness. Every unit is assembled with floating metal face seals for dust and oil protection, then filled with high-viscosity oil to ensure self-lubrication throughout the product's service life β typically 3,000β6,000 working hours depending on application conditions.
