MTWB solid lubricant bearings are designed for applications where traditional grease or oil lubrication is difficult, unreliable or requires frequent maintenance.
By integrating solid lubrication materials into the bearing structure, these bearings provide continuous lubrication performance, reduced friction and extended service life under demanding operating conditions.
The solid lubrication design makes them suitable for rotary support systems operating in high temperature, dusty, vacuum, heavy load or maintenance-restricted environments.
Types of Solid Lubricant:

✓ 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, which means re-greasing is completely
eliminated.The embedded sealing design effectively prevents invasion of
pollutants, improves water flushing resistance by 80%, and significantly
reduces the risk of downtime caused by lubrication failure.
✓ Extended Service Life
Solid
lubricant content is 2-4 times higher than traditional lubricants, and
bearing service life can be extended by more than 3 times, significantly
reducing the frequency of spare parts replacement.
✓ Superior Contamination Prevention
Solid
lubricant is in close contact with the raceway and rollers, almost
filling the whole bearing. The remaining space in the body can
effectively prevent pollutants from entering the bearing, protecting the
bearing from maintenance-related issues.
✓ Zero Lubricant Leakage
Lubricating
oil is stored in the micropores inside the polymer based on surface
tension. During operation, lubricating oil is transferred to the
material surface under capillary action. When operation stops,
lubricating oil is reabsorbed into the polymer for "storage," preventing
environmental pollution caused by lubricating oil leakage.
✓ Clean & Pollution-Free Operation
Suitable
for high ambient temperatures (up to 200°C/392°F), high humidity, dust,
and chemical corrosion environments, and therefore has excellent
performance in metallurgy, mining, food processing, ships, and other
scenes.The solid lubrication rotary support leaves the oil in the bearing and
has an integral bearing seal to further improve the preservation of oil.
✓ Excellent Anti-Rinsing Capability
Solid lubricants can support integral seals and have very good anti-rinsing ability.
