Against this backdrop of intensifying global demand for extra heavy duty bearings, MTWB's solid lubrication bearing solutions are gaining recognition among OEM manufacturers and equipment operators seeking reliable, maintenance-free performance under extreme operating conditions.
MTWB Solid Lubrication Bearings are engineered specifically for applications where conventional lubrication is difficult, impossible, or uneconomical. Designed with embedded solid lubricants utilizing advanced polymer matrix adsorption technology, these self-lubricating bearings deliver reliable performance under high loads, low speeds, high temperatures (up to 200°C), dusty environments, and heavy industrial operating conditions.
The polymer material is injected into the bearing through a specialized process, where it adsorbs saturated lubricating oil. 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.
MTWB Solid Lubrication Bearings are deployed across a wide range of heavy-duty sectors:
Construction Machinery: Excavator booms, crane pivot points, slewing rings, earthmoving equipment
Mining Equipment: Crushers, conveyors, metallurgical equipment, ore processing machinery
