Agricultural machinery operates under challenging conditions including dust, mud, moisture, fertilizer contamination and heavy shock loads.
MTWB solid agricultural bearings are designed for reliable operation in equipment such as seeders, planters, harvesters and tillage machinery.
With optimized sealing structures, robust materials and customized configurations, MTWB agricultural bearings help reduce maintenance frequency and improve machine uptime.
With polymer matrix adsorption saturated lubricant technology, the lubricant seamlessly adheres to the raceway and rolling elements without the need for an external oil supply system – re-greasing is completely eliminated.
The embedded sealing design effectively prevents pollutant invasion, improves water flushing resistance by 80%, and significantly reduces downtime risks caused by lubrication failure.
Solid lubricant content is 2–4 times higher than traditional lubricants, and bearing service life can be extended by more than 3 times, significantly reducing the frequency of spare parts replacement.
The solid lubricant remains in close contact with the raceway and rollers, almost filling the entire bearing. The remaining space inside the bearing effectively prevents pollutants (dust, particles, debris) from entering, protecting the bearing from contamination.
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," preventing environmental pollution caused by lubricant leakage.
Suitable for high ambient temperatures (up to 200°C), high humidity, dust, and chemical corrosion environments.The integral bearing seal further improves oil retention.
Solid lubricants support integral seals and provide outstanding resistance to water rinsing – ideal for wet agricultural conditions.
Solid lubricants cannot be used in organic solvents such as acetone, petroleum benzene, or white kerosene.

MTWB Solid Agricultural Bearings are specifically designed to reduce bearing failures caused by dust, particles, and debris intrusion in agricultural machinery, significantly improving equipment reliability.
Typical agricultural applications include:
Tractors & Harvesters – wheel hubs, drive shafts, and linkage systems
Combine Harvesters – threshing mechanisms and grain handling systems
Agricultural Implements – plows, seeders, and tillage equipment
Irrigation Systems – pump bearings and water-exposed components
Feed Processing Equipment – mixers, grinders, and conveyors
Grain Handling Systems – elevators, augers, and dryers
Sprayers & Crop Protection Equipment – high-moisture environments
Hay & Forage Equipment – balers, mowers, and conditioners
Beyond agriculture, these bearings also excel in: food and beverage machinery, elevators, ferrous metallurgy, petrochemical machinery, construction and mining equipment, ports machinery, papermaking equipment, and cement machinery.

A solid agricultural bearing is a specially designed bearing used in farming machinery, providing reliable performance under dust, moisture and heavy load conditions.
Agricultural bearings are commonly used in seeders, planters, harvesters, cultivators and other farming equipment.
Agricultural bearings usually require stronger sealing, better contamination resistance and higher durability compared with standard industrial bearings.
Yes. MTWB provides OEM agricultural bearing solutions including customized seals, lubrication, dimensions and performance requirements.
