MTWB Solid Lubricated Tapered Roller Bearings are designed for applications where conventional grease lubrication is difficult, unreliable or requires frequent maintenance. By integrating solid lubrication technology into tapered roller bearing structures, these bearings provide stable friction performance, extended service intervals and reliable operation under harsh working conditions.
Designed with advanced polymer matrix embedded solid lubricant technology, this tapered roller bearing delivers 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.

The solid lubrication mechanism is based on a proprietary polymer material injected into the bearing through a specialized process. This polymer material adsorbs saturated lubricating oil, ensuring that the lubricant remains 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; when operation stops, the lubricating oil re-adheres to the polymer for “storage”.This unique circulation mechanism ensures consistent lubrication throughout the bearing service life.

Note: Lubricating oil (grease) content ranges from 40% to 95%
As a customized bearing manufacturer, MTWB offers tailored Solid Lubrication TRB solutions to meet specific application requirements.
Key customizable parameters include:
Bearing dimensions (inner diameter, outer diameter, width) – tailored to your equipment specifications
Load capacity – optimized for radial and axial load requirements
Solid lubricant type – selection from multiple polymer formulations based on operating temperature, speed, and environmental conditions
Lubricant content – adjustable from 40% to 95% based on application needs
Sealing design – integrated sealing for enhanced contamination protection
Speed rating – customizable with limit speeds ranging from 1,000 RPM to 5,000 RPM depending on lubricant type
With polymer matrix adsorption saturated lubricant technology, a lubricant seamlessly adheres to the raceway and rolling elements without the need for an external oil supply system – re-greasing is completely eliminated.
Solid lubricant content is 2–4 times higher than traditional lubricants, extending bearing service life by more than 3 times and 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 within the body effectively prevents pollutants from entering, protecting the bearing from contamination-related failures.
Lubricating oil is stored in the micropores inside the polymer. During operation, oil is transferred to the material surface under capillary action; when operation stops, oil is reabsorbed into the polymer for “storage” – eliminating environmental pollution caused by lubricating oil leakage.
Suitable for ambient temperatures up to 200℃, as well as high humidity, dust, and chemical corrosion environments.The solid lubrication bearing retains oil within the bearing and features an integral bearing seal to further improve oil retention.
Solid lubricants support integral seals and provide very good anti-rinsing ability, making them ideal for washdown and high-moisture environments.
Ideal for applications where lubricant contamination is a critical concern, including food processing and clean manufacturing environments.
