MTWB Solid Lubrication Cylindrical Roller Bearings (CRB) are engineered for demanding industrial environments where conventional grease lubrication is difficult or impossible. Featuring advanced solid lubricant technology, these bearings provide maintenance-free operation, enhanced contamination resistance, and extended service life in mining, steel production, conveyors, food processing, and heavy-duty machinery. MTWB offers OEM and customized solid lubrication CRBs that deliver high radial load capacity, reduced downtime, and reliable performance under harsh operating conditions.
MTWB Solid Lubrication CRB Cylindrical Roller Bearing is a high-performance self-lubricating bearing solution engineered for applications where conventional lubrication is difficult, impossible, or uneconomical. Designed with embedded solid lubricant technology, this cylindrical roller bearing delivers reliable operation under high loads, low speeds, elevated temperatures, dusty environments, and heavy industrial conditions.
As a specialized solid lubrication bearing, the CRB cylindrical roller bearing eliminates the need for external oil supply systems, significantly reducing maintenance costs while extending equipment service life.MTWB helps OEM manufacturers improve equipment reliability and achieve maintenance-free operation through application-specific bearing solutions.

The Solid Lubrication CRB Cylindrical Roller Bearing utilizes an advanced polymer matrix adsorption technology. Polymer material is injected into the bearing through a specialized process, where it adsorbs saturated lubricating oil.The polymer ensures 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 oil slowly moves to the material surface through capillary action. When operation stops, the lubricating oil re-adheres to the polymer for “storage”.This self-regulating lubrication cycle ensures consistent performance throughout the bearing’s service life.
| Parameter | Specification |
|---|---|
| Bearing Type | Cylindrical Roller Bearing (CRB) with Solid Lubrication |
| Lubrication Type | Solid Lubricant (Polymer Matrix Adsorption) |
| Lubricant Content | 40–95% (customizable) |
| Operating Temperature Range | Up to 200°C (depending on lubricant grade) |
| Speed Capability | Up to 5,000 RPM (depending on design and lubricant grade) |
| Food Grade Option | Available |
With polymer matrix adsorption saturated lubricant technology, the lubricant seamlessly adheres to the raceway and rolling elements without requiring 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 the risk of downtime caused by lubrication failure.
Solid lubricant content is 2–4 times higher than traditional lubricants. 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 effectively prevents pollutants from entering the bearing, protecting it from contamination-related failures.
Lubricating oil is stored in the micro-pores 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 preservation.
√Excellent Anti-Rinsing Capability
Solid lubricants support integral seals and provide very good anti-rinsing ability.
