Self-Lubricating Bearings Engineered for Dusty, High-Moisture, and Demanding Farm Environments
MTWB Solid Lubrication Bearings for Agricultural Machinery are purpose-engineered self-lubricating bearing solutions designed to withstand the harshest operating conditions found in modern farming equipment. From combine harvesters and tractors to balers, sprayers, and tillage implements, agricultural machinery operates in environments saturated with dust, soil particles, crop debris, moisture, and extreme temperature variations—conditions that rapidly degrade conventional grease-lubricated bearings.
MTWB's solid lubrication technology addresses these challenges head-on. By embedding solid lubricants directly into the bearing structure, these bearings deliver reliable self-lubricating performance without the need for external oil supply systems or frequent regreasing.The result is extended service life, reduced maintenance downtime, and significantly improved equipment reliability during critical planting and harvesting seasons.
MTWB Solid Lubrication Bearings utilize an advanced polymer matrix technology. Polymer material is injected into the bearing in a specialized process, where it adsorbs saturated lubricating oil. The lubricating oil is "stored" in the micropores within the polymer based on surface tension. During operation, a small portion of the lubricating oil slowly migrates to the material surface through capillary action, ensuring tight and continuous contact with the raceways and rollers. When operation stops, the lubricating oil re-adheres to the polymer for "storage," creating a self-sustaining lubrication cycle that effectively prevents contaminants from entering the bearing interior.

With polymer matrix adsorption saturated lubricant technology, lubricant seamlessly adheres to the raceway and rolling elements without the need for an external oil supply system—eliminating regreasing completely. The embedded sealing design effectively prevents invasion of pollutants and improves water flushing resistance by 80%, significantly reducing downtime risk caused by lubrication failure.
Solid lubricant content is 2-4 times higher than traditional lubricants, enabling bearing service life to be extended by more than 3 times. This dramatically reduces the frequency of spare parts replacement—a critical advantage during peak agricultural seasons when equipment downtime is most costly.
The solid lubricant is in close contact with the raceway and rollers, almost filling the entire bearing interior.
The remaining space within the body effectively prevents dust, soil particles, crop residue, and other pollutants from entering the bearing, protecting it from contamination-related failure.
Lubricating oil is stored in the micropores inside the polymer based on surface tension. During operation, oil transfers to the material surface under capillary action; when operation stops, oil is reabsorbed into the polymer for "storage". This prevents environmental pollution caused by lubricating oil leakage—particularly important for environmentally sensitive agricultural operations.
Solid lubrication bearings perform exceptionally well in high ambient temperatures (up to 200°C), high humidity, dust-laden, and chemically corrosive environments. This makes them ideally suited for the extreme conditions encountered in agricultural machinery, from scorching summer harvests to wet spring planting.
Solid lubricants support integral seals and provide excellent anti-rinsing ability, ensuring reliable performance even when equipment is subjected to high-pressure washing or operates in wet field conditions.
MTWB Solid Lubrication Bearings are specifically engineered to reduce bearing failures caused by dust, particles, moisture, and other debris intrusion—dramatically improving equipment reliability in agricultural operations, Key applications include:
| Application Area | Specific Equipment | Key Challenge Addressed |
|---|---|---|
| Harvesting Equipment | Combine harvesters, forage harvesters, cotton pickers | Dust, crop debris, continuous operation |
| Tillage & Soil Preparation | Plows, harrows, cultivators, seedbed preparators | Soil particles, impact loads, moisture |
| Planting & Seeding | Seed drills, planters, air seeders | Dust, precision requirements, chemical exposure |
| Hay & Forage Equipment | Balers, mowers, tedders, rakes | Crop debris, moisture, dusty conditions |
| Spraying Equipment | Self-propelled sprayers, tow-behind sprayers | Chemical corrosion, moisture, dust |
| Material Handling | Grain augers, conveyors, elevators | Abrasive dust, continuous duty |
| Tractor Systems | PTO shafts, 3-point hitch components, steering systems | Variable loads, dirt, moisture |
| Irrigation Equipment | Center pivots, pumps, gearboxes | Water exposure, corrosion, continuous operation |
The application of solid lubrication bearings in agricultural machinery reduces the failure of bearings caused by dust, particles, and other debris intrusion, while improving the overall reliability of equipment
