Wear-resistant material & stable heat treatment
High-carbon chromium bearing steel with optimized heat treatment to enhance wear and fatigue resistance under continuous impact loads.
Agricultural equipment
Agricultural machinery operates continuously in harsh outdoor conditions with heavy dust, mud, high humidity and strong vibration, requiring bearings with excellent sealing, dirt resistance, impact resistance and low-maintenance performance. Agricultural bearings are widely applied in tractors, harvesters, seeders, tillers, balers and agricultural sprayers, covering wheel hubs, PTO drive shafts, threshing drums, tiller shafts, seeding discs, steering and suspension hinge parts. Difu provides professional agricultural bearing solutions featuring superior sealing, mud and dust resistance, vibration resistance and long service life. With reinforced multi-lip sealing design, optimized self-aligning structure, heavy-load wear-resistant materials and long-life lubrication, our bearings effectively prevent dirt intrusion, sticking noise and premature failure. We offer maintenance-free bearing units and custom solutions for various harsh farm working conditions, reducing downtime and maintenance costs for agricultural equipment.

Industry Solutions
Tractor wheel hub
Tractor wheel hub bearings are core load-bearing components of agricultural walking systems, operating continuously in harsh farm environments with mud, dust, humidity and bumpy roads. They withstand heavy loads, compound impacts and high-frequency vibration, which easily cause seal failure, dirt intrusion, abnormal noise and premature wear. Difu delivers professional tractor hub bearing solutions featured with heavy load capacity, reinforced sealing, vibration resistance and maintenance-free performance. Adopting multi-lip reinforced sealing and optimized self-aligning structure, our bearings effectively block mud and dust infiltration and compensate for shaft misalignment in complex field conditions. Upgraded wear-resistant materials and long-life anti-fouling lubrication ensure excellent fatigue and impact resistance. Suitable for front and rear wheel hubs of various tractors, we support custom parameter matching and mass supply, minimizing equipment downtime and maintenance costs for all-weather agricultural operations.
Harvester drum
Combine harvester drum bearings undertake continuous high-speed operation during harvest seasons, subject to alternating compound loads, intense vibration, crop debris accumulation and field moisture erosion. Conventional bearings often suffer from thermal expansion jamming, lubrication failure, raceway fatigue peeling and stalling noise, causing costly harvest downtime. Difu provides customized heavy-duty bearing solutions for harvester drum operation, featuring anti-clogging, thermal deformation resistance, high-speed stability and long fatigue life. Optimized C3/C4 internal clearance compensates for thermal expansion under continuous high-speed rotation to avoid jamming. Multi-layer anti-dust and debris-proof sealing structure prevents crop residue and fine dirt infiltration. High-temperature durable grease adapts non-stop seasonal operation and slows lubrication degradation. With hardened material treatment for enhanced fatigue resistance, our bearings extend service life under high-intensity working conditions. We support custom parameter matching and stable mass supply, minimizing maintenance downtime and ensuring efficient and continuous harvesting operations.
Baler Spindle
Baler main shaft bearings are core load-bearing and transmission components for forage compression, operating with frequent start-stop cycles, periodic alternating impact loads and dense crop dust invasion, which easily cause abrasive wear, lubrication failure, seal clogging and shaft deflection jamming. Difu launches exclusive baler bearing solutions featuring impact resistance, anti-clog performance, stable load capacity and long-term durability. We enhance overall rigidity and raceway wear resistance to withstand cyclic impact loads, and adopt dedicated anti-winding sealing structures to block fine straw and forage dust infiltration. The anti-precipitation long-life lubrication formula adapts intermittent working conditions, preventing lubrication drying and abrasive wear caused by alternating wet and dry environments. Customized for various straw and hay baler equipment, our bearings support parameter optimization and mass supply, reducing equipment shutdown frequency and replacement costs to ensure stable and efficient baling operations.
