MTWB Solid Lubrication Bearings are engineered for applications where conventional lubrication is difficult, impossible, or uneconomical. Designed with embedded solid lubricants, these customized bearings provide reliable self-lubricating performance under high loads, low speeds, high temperatures, dusty environments, and heavy industrial operating conditions. MTWB helps OEM manufacturers improve equipment reliability while reducing maintenance costs and extending service life through application-specific bearing solutions.
Polymer material is injected into the bearing in a special way. The polymer material adsorb saturated lubricating oil, ensuring that the plastic oil is tightly and continuously in contact with the raceways and rollers, effectively preventing contaminants from entering the bearing interior; the lubricating oil is “stored” in the micro-pores within the polymer based on surface tension. During operation, a small portion of the lubricating oil slowly moves to the material surface due to capillary action, and when the operation stops, the lubricating oil re-adheres to the polymer for “storage”.

√ Lifetime maintenance free
With polymer matrix adsorption saturated lubricant technology, a lubricant seamlessly adheres to the raceway and rolling elements without the need of an external oil supply system, which means re-greasing is completely eliminated. The embedded sealing design effectively prevents invasion of pollutants, improves water flushing resistance by 80%, and reduces significantly the risk of downtime caused by lubrication failure.
√Long service life
Solid lubricant content is 2-4 times higher than traditional lubricants, baaring service life can be extended by more than 3 times, that significantly reducing the frequency of spare parts replacement.
√Prevent contamination
Solid lubricant is in close contact with the raceway and rollers, almost filling the whole bearing. The remaining space in the body can effectively prevent pollutants from entering the bearing, so as to protect the bearing from maintenance.
√Eliminate lubricant leakage
Lubricating oil is stored in the micropores inside the polymer based on surface tension. During operation, lubricating oil is transferred to the material surface under capillary action. When operation stops, lubricating oil is reabsorbed into the polymer for "storage", so as to prevent environmental pollution caused by lubricating oil leakage.
√Clean and less polluted
Solid lubricant is suitable for high ambient temperature (up to 200 ℃), high humidity, dust and chemical corrosion environment, and therefore has an excellent performance in metallurgy,mining, food processing, ships and other scenes. The solid lubrication bearing leaves the oil in the bearing and has an integral bearing seal Further improve the preservation of oil.
√Anti-rinsing
Solid lubricants can support integral seals and has very good anti-rinsing ability.
√Precaution
Solid lubricant cannot be used in organic solvents (acetone, petroleum benzene, white kerosene, etc.)
The end goal of structural optimization is to improve the bearing performance to the best application costing.
Low frictional composite materials are researched to improve the reliability and durability of solid lubricant.
The end goal of this process is to predict and extending solid lubricated bearing life.
Food and beverage machinery
The application in food machinery is to solve the pollution problem caused by the leakage of traditional bearing lubricating oil (grease), and improve the food safety level and pollution problem.
Elevator
The application in elevator traction and transmission parts is to prevent oil leakage.
Ferrous Metallurgy
The application in iron and steel metallurgical equipment is to prevent the failure of grease caused by iron oxide dust and water spray pollution hence reducing the consumption of grease.
Petrochemical Machinery
The application in petroleum machinery is to improve the production efficiency hence reducing the maintenance cost under harsh environment.
Construction, mining & ports machinery
The application in construction machinery, mining machinery and ports is to reduce intrusion of dust, particles, water vapor and other debris to the bearing that will lead to bearing failures hence equipment reliability is improved.
Agricultural machinery
The application in agricultural machinery is to reduce the failure of bearings caused by dust, particles and other debris intrusion and improve the reliability of equipment.
Papermaking equipment
The application in papermaking machinery to reduce intrusion of dust,particles and other debris to the bearing.
Cement machinery
The application in cement machinery is to reduce bearing failures due to high temperature, moisture and smoke in the working condition. There are other factors such as vibration that will affect the service life of bearing.
