MTWB Solid Lubrication Bearings are engineered specifically for heavy-duty equipment operating in construction, mining, and port machinery applications where conventional lubrication is difficult, impossible, or uneconomical.Designed with embedded solid lubricants using advanced polymer matrix technology, these self-lubricating bearings deliver reliable performance under high loads, low speeds, high temperatures, dusty environments, and other severe industrial operating conditions. MTWB helps OEM manufacturers and equipment operators improve reliability while reducing maintenance costs and extending service life through application-specific bearing solutions.
MTWB Solid Lubrication Bearings utilize 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 while 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 through capillary action; when operation stops, the lubricating oil re-adheres to the polymer for "storage".This innovative mechanism ensures consistent lubrication throughout the bearing's service life without external intervention.
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
| Harsh Environment Compatibility | Suitable for high ambient temperatures (up to 200°C), high humidity, dust, and chemical corrosion environments |
The integral bearing seal further improves oil retention
| Excellent Anti-Rinsing Capability | Solid lubricants support integral seals with very good anti-rinsing ability, making them ideal for wash-down environments common in port and mining operations. |
| Clean & Environmentally Friendly | Leaves oil contained within the bearing, eliminating grease leakage and run-off that can contaminate waterways and work sites |
| Parameter | Specification |
|---|---|
| Lubrication Type | Solid lubrication with polymer matrix adsorption technology |
| Operating Temperature Range | Up to 200°C (392°F) |
Note: Solid lubricant cannot be used in organic solvents such as acetone, petroleum benzene, or white kerosene.
