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 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.

Solid lubrication bearings can significantly reduce or eliminate routine relubrication requirements under suitable operating conditions, helping minimize maintenance downtime in agricultural machinery.
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.
How to Select Solid Lubrication Bearings for Agricultural Machinery
When selecting a solid lubrication bearing for agricultural machinery, engineers should consider operating load, rotational speed, temperature, dust exposure, water contamination, washing conditions, required precision and available installation space. MTWB can customize bearing dimensions, materials, solid lubricant formulations, sealing configurations and precision grades according to specific application requirements.
Agricultural machinery often operates in harsh and unpredictable environments where conventional grease-lubricated bearings may require frequent maintenance. Dust, soil particles, crop debris, water, moisture and high-pressure washing can accelerate lubricant contamination and bearing wear. Solid lubrication bearings provide a self-lubricating solution that can help reduce relubrication requirements and improve bearing reliability in demanding agricultural applications.
Agricultural equipment frequently operates in dry and dusty environments, especially during harvesting, planting and tillage operations. Fine dust can enter bearing assemblies and contaminate conventional grease, increasing friction and accelerating wear. Solid lubrication bearings use a solid lubricant integrated into the bearing structure, helping provide continuous lubrication without relying on frequent grease replenishment. This makes them suitable for agricultural machinery exposed to high levels of airborne dust.
Tractors, cultivators, plows and other farm equipment often work directly in soil and muddy conditions. Soil particles can contaminate conventional lubricants and contribute to abrasive wear on bearing surfaces. Solid lubrication bearings can reduce dependence on external grease lubrication and are suitable for applications where exposure to soil and contaminants makes regular relubrication difficult.
Harvesters, balers, seeders and other agricultural machines are commonly exposed to crop residues such as straw, husks, leaves and chaff. These materials can accumulate around bearing housings and contribute to contamination and maintenance challenges. Solid lubrication bearings can provide reliable lubrication performance while helping reduce routine greasing requirements in agricultural equipment exposed to crop debris.
Agricultural machinery may operate in rain, irrigation areas, wet fields and humid environments. Water and moisture can affect conventional lubricants and may contribute to corrosion and premature bearing failure. Depending on the bearing design and sealing configuration, solid lubrication bearings can offer a suitable solution for applications where resistance to moisture and reduced relubrication requirements are important.
Agricultural machinery is often cleaned with high-pressure water after operation to remove soil, mud and plant residues. Conventional grease can be displaced or washed out during intensive cleaning, potentially increasing the need for frequent relubrication. Solid lubrication bearings can help reduce dependence on external grease and may be advantageous in equipment exposed to frequent washing, provided that the overall bearing sealing and housing design are properly matched to the application.
Many agricultural machines contain bearings located in areas that are difficult or time-consuming to access. Regular greasing in these locations can increase maintenance workload and equipment downtime. Solid lubrication bearings can reduce the need for routine relubrication, making them a practical option for hard-to-reach bearing positions and equipment designed to minimize scheduled maintenance.
Agricultural machinery is often used intensively during critical planting and harvesting seasons, when unexpected bearing maintenance can cause significant downtime. By reducing routine lubrication requirements and supporting reliable operation under demanding conditions, solid lubrication bearings can help improve equipment availability during busy agricultural seasons. For OEMs and agricultural machinery manufacturers, selecting the appropriate solid lubrication bearing design can contribute to lower maintenance requirements and more reliable equipment operation.
