BAA-0004

BAA-0004 Lubrication-Free Agricultural Hub Unit

High Load Capacity, Waterproof & Dustproof for Tractors/Harvesters

Product Overview

Jiangsu Wallong-Hsin Machinery Engineering Co., Ltd., a 30-year benchmark in China’s agricultural machinery core parts industry, proudly launches the BAA-0004 Agricultural Hub Unit. Specifically engineered for tractors, seeders, harvesters, rotary tillers, and other agricultural machinery, this hub unit integrates a lubrication-free design and advanced 5-lip sealing technology. It excels in harsh field conditions—muddy terrain, dusty environments, and low-temperature climates—effectively solving the pain points of traditional hubs: frequent relubrication, easy water/mud infiltration, and short service life. The BAA-0004 redefines agricultural machinery operations with enhanced efficiency, environmental friendliness, and cost-effectiveness.

JSW Agricultural Hub Unit Core Advantages

1.Lubrication-Free Design: Cost Reduction & Environmental Sustainability

The BAA-0004 eliminates the need for daily or monthly relubrication, completely cutting labor and material costs associated with lubrication. Compared to traditional hubs, it reduces lubricant consumption by 90%, slashing operational expenses (lubrication costs account for only 7.5% of total ownership costs). Its unique sealing technology prevents grease leakage, avoiding soil contamination and aligning with global sustainable agriculture development goals. This lubrication-free agricultural hub is the ideal choice for eco-conscious farmers and machinery manufacturers.

2.Superior Protection + Extended Service Life: Uninterrupted Operation

Equipped with a 5-lip oil seal and anti-contamination protective cover, the hub unit provides dual protection, effectively blocking straw, stones, sediment, chemical fertilizers, and other impurities from entering. It passed a 1000-hour harsh muddy environment test without failure and maintains stable performance in low-temperature tillage (-10℃). With a service life 3 times longer than traditional bearings, it reduces equipment replacement frequency, lowering the environmental impact of manufacturing and disposal by 2/3. Say goodbye to unexpected downtime—this long-lasting farm hub ensures continuous field productivity.

3.High Load-Bearing + Easy Installation: Boost Operational Efficiency

Featuring a double row bearing design, the BAA-0004 delivers exceptional radial and axial load-bearing capacity, perfectly matching the heavy-duty demands of agricultural machinery. Its pre-processed flanged outer ring allows quick adaptation to various agricultural implements—no professional tools required for installation or maintenance. The significantly reduced bearing failure rate increases field operation productivity by 150%, minimizing productivity losses caused by equipment breakdowns. This easy-to-install, high-load agricultural hub is designed for maximum efficiency.

Authoritative Performance Tests

The BAA-0004 Agricultural Hub Unit has undergone rigorous performance testing to meet international standards:

Fatigue Test: Passed 1 million revolutions of high-intensity fatigue testing; stable operation for ≥2 million revolutions under normal working conditions—far exceeding industry benchmarks.
Muddy Sealing Test: 1000-hour exposure to harsh muddy environments with zero water or sediment infiltration; 100% oil seal integrity.
Low-Temperature Adaptability Test: Smooth rotation and unattenuated load-bearing performance at -10℃, validated for cold-region tillage.
Environmental Certification: Complies with international agricultural machinery environmental standards; grease-free leakage design holds agricultural sustainable development certification.
