MTWB Solid Lubrication Bearings are engineered specifically for ferrous metallurgy applications where conventional lubrication is difficult, impossible, or uneconomical.Designed with embedded solid lubricants, these self-lubricating bearings deliver reliable performance under extreme operating conditions commonly found in steel mills and metal processing facilities—including high loads, low speeds, elevated temperatures, dusty environments, and heavy industrial operations.
MTWB helps OEM manufacturers and metallurgical plant operators improve equipment reliability while reducing maintenance costs and extending service life through application-specific bearing solutions.
The solid lubrication technology employs a polymer material injected into the bearing through a specialized process. This polymer adsorbs saturated lubricating oil, ensuring continuous contact with raceways and rollers while effectively preventing contaminants from entering the bearing interior.
The lubricating oil is "stored" in the micropores within the polymer based on surface tension. During operation, a small portion of the oil slowly migrates to the material surface through capillary action. When operation ceases, the oil re-adheres to the polymer for "storage," creating a self-sustaining lubrication cycle.
✓ Lifetime Maintenance Free
With
polymer matrix adsorption saturated lubricant technology, lubricant
seamlessly adheres to raceway and rolling elements without the need for
an external oil supply system—eliminating re-greasing entirely. The
embedded sealing design prevents pollutant invasion, improves water
flushing resistance by 80%, and significantly reduces downtime risks
caused by lubrication failure.
✓ Extended Service Life
Solid
lubricant content is 2–4 times higher than traditional lubricants,
extending bearing service life by more than 3 times and substantially
reducing spare parts replacement frequency.
✓ Contamination Prevention
Solid
lubricant remains in close contact with raceways and rollers, nearly
filling the entire bearing. The remaining internal space effectively
blocks pollutants from entering, protecting the bearing throughout its
service life.
✓ Zero Lubricant Leakage
Lubricating
oil is stored in micropores based on surface tension. During operation,
oil transfers to the surface via capillary action; when operation
stops, it is reabsorbed into the polymer—preventing environmental
pollution caused by lubricant leakage.
✓ Extreme Environment Performance
Suitable
for high ambient temperatures up to 200°C, high humidity, dust, and
chemically corrosive environments. The integral bearing seal further
improves oil retention.
✓ Excellent Anti-Rinsing Capability
Solid lubricants support integral seals with superior resistance to water flushing and washout.
Important Note: Solid lubricant bearings should not be used in organic solvents such as acetone, petroleum benzene, or white kerosene.

Solid lubrication bearings are used in selected steel mill and ferrous metallurgy equipment where conventional grease or oil lubrication is difficult to maintain. Typical applications include rolling mills, continuous casting machines, conveyors, material handling equipment, furnace-related machinery, and other industrial systems exposed to demanding operating conditions. They can help reduce relubrication requirements and maintain reliable bearing performance in environments with high loads, dust, water, and elevated temperatures.
Ferrous metallurgy equipment often operates under heavy loads, high temperatures, water spray, dust, scale particles, and other harsh conditions. Solid lubrication bearings are suitable for selected applications because they can provide continuous lubrication without relying solely on frequent external grease replenishment. Their design can also help reduce maintenance requirements and improve operational reliability where conventional lubrication systems may be difficult to access or maintain.
Yes. Solid lubrication bearings can be designed for selected high-temperature steel mill applications. However, the maximum operating temperature depends on the bearing material, solid lubricant, base material, clearance, load, speed, and surrounding environment. For high-temperature applications, engineers should evaluate continuous and peak temperatures and select suitable materials and lubrication systems. MTWB can provide customized solutions for applications requiring specific temperature and performance requirements.
Solid lubrication bearings are often described as maintenance-free or maintenance-reduced because they can significantly reduce or eliminate the need for regular relubrication under suitable operating conditions. However, maintenance requirements depend on the specific bearing design and application. Periodic inspection of the bearing, shaft, housing, seals, and surrounding equipment may still be recommended to ensure reliable long-term operation.
Yes. Solid lubrication bearings can be designed for applications exposed to water, dust, metal particles, and other contaminants. This makes them suitable for selected steel mill and metallurgical environments where water spray and airborne particles are common. The actual resistance depends on the bearing structure, sealing configuration, material selection, surface treatment, and operating conditions. Proper bearing selection and equipment design are essential for achieving reliable performance in highly contaminated environments.
Yes. MTWB can customize solid lubrication bearing solutions for steel mill and ferrous metallurgy equipment according to specific application requirements. Customization may include bearing dimensions, materials, solid lubricant formulation, internal clearance, load capacity, temperature requirements, sealing configurations, and other performance parameters. MTWB can work with OEMs and equipment manufacturers to develop customized bearing solutions for rolling mills, continuous casting equipment, conveyors, and other demanding industrial applications.
