MTWB Solid Lubrication NRB Needle Roller Bearing
The solid lubrication technology employs polymer material injected into the bearing through a specialized process. The 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.
This self-regulating lubrication cycle ensures consistent performance throughout the bearing's service life.
| Parameter | Details |
|---|---|
| Bearing Type | Needle Roller Bearing (NRB) with Solid Lubrication |
| Lubrication Technology | Polymer matrix adsorption with saturated lubricant |
| Operating Temperature | Up to 200°C (392°F) |
| Customization | Available in various sizes and configurations upon request |
✓ Lifetime Maintenance-Free
With
polymer matrix adsorption saturated lubricant technology, lubricant
seamlessly adheres to the raceway and rolling elements without the need
for an external oil supply system. Re-greasing is completely eliminated,
and the embedded sealing design effectively prevents the invasion of
pollutants.
✓ Extended Service Life
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.
✓ Superior Contamination Prevention
Solid
lubricant maintains 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 failure.
✓ Zero Lubricant Leakage
Lubricating
oil is stored in micropores inside the polymer. 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.
✓ Clean & Pollution-Resistant Operation
Suitable
for high ambient temperatures (up to 200°C), high humidity, dust, and
chemical corrosion environments. Excellent performance in metallurgy,
mining, food processing, marine, and other demanding scenes.
✓ Excellent Anti-Rinsing Capability
Solid
lubricants support integral seals and provide outstanding anti-rinsing
ability, ensuring reliable operation even in washdown environments.
✓ Application-Specific Customization
MTWB
understands that structural optimization improves bearing performance
for specific applications. Low-frictional composite materials are
continuously researched to improve the reliability and durability of
solid lubricants.
